00:00:00:00 – 00:00:14:10
Speaker 1
Chat. And, I just want to make sure, we have, everybody that I think is on the line here. We have Pendleton office, and we have, Jim Gurkha is there anybody else we have on the line?
00:00:14:12 – 00:00:15:28
Speaker 2
Today?
00:00:16:00 – 00:00:43:03
Speaker 1
Okay. Jim, are you on the go to meeting? I’m unable I, I need to get my i.t. Person here because I don’t have administrative privileges. Apparently is try to download some new software. Oh, okay. Okay. Okay. Well, let’s go ahead and begin. And before we show, some examples and, and loops here that, we have, packaged and ready to go.
00:00:43:06 – 00:00:55:16
Speaker 1
Let me just ask Pendleton if you have any, anything you’d like to share or discuss or have questions about, maybe something that’s occurred recently and particularly satellite related.
00:00:55:18 – 00:00:58:01
Speaker 3
No, nothing to pass on. Really.
00:00:58:03 – 00:01:26:00
Speaker 1
Okay. Okay. Well, then let’s go ahead and lead off with, Scott Lindstrom, from Simms in Wisconsin. Okay. I have a bunch of different things to talk about today. That I’ve loaded up here. And the first thing I want to start with is goes 12. It goes 12 was launched in 2001, and it is being shut off.
00:01:26:03 – 00:01:50:06
Speaker 1
The good the ghost 12 cylinder has been shut off. The ghost 12 imager will be shut off tomorrow. So ghost 12 has been operating as a, provider of data for South America. So it’s called Goes-r now for South America. And when that shuts off, a big data source is going to be gone then. And that’s actually going to impact the ISO.
00:01:50:08 – 00:02:16:26
Speaker 1
The ISO schedule for goes east. So maybe not that important for Pendleton because I don’t think you’re calling our ISO for Ghost East. But what’s going to happen is, there are going to be two different scans, two different sectors that are scanned during our ISO that give. So this this is the ghost South America, a sector that is scanned over the Amazon at the top of the hour.
00:02:16:28 – 00:02:45:03
Speaker 1
And then there’s also a B sector that’s scanned at the bottom of the hour. So it’s zero and 30. Here’s the B sector. And these are just to provide some data to South America at times, when otherwise it wouldn’t happen. So during an hour during the past hour. So as for goes east, there was what was called the South Hemisphere short sector, which just gave you some information off the coast of South America.
00:02:45:25 – 00:03:06:19
Speaker 1
My opinion, it wasn’t very useful because it’s just looking over the ocean. So maybe for El Nino, it was interesting, but, for people who lived on land and then lots of people in South America, and now it just wants to provide them with some information. So they changed it. So these are two minute sectors that I showed you as both A sector and the B sector.
00:03:06:19 – 00:03:29:24
Speaker 1
So take two minutes out of the hour. So schedule just at the top at the bottom of the hour. That’s it’s giving a little more dated South America now that goes 12 is being shut off. Another thing I wanted to talk about today, is there have been this is for the tropics. So again, sorry, Pendleton, we’re focusing a little bit on the eastern part of the U.S, but we’ll go to the western part in just a bit.
00:03:30:05 – 00:03:56:12
Speaker 1
There has been a there have been some tremendous Saharan air layer outbreaks over the Atlantic Ocean. I’m going to click this. I’m not sure how well this is going to show up on your go to meeting. But you can see the haze, the hazy signature of this of the Saharan dust out over the Atlantic Ocean. And that’s important because when you have this, these Saharan air layer outbreaks, it really suppresses tropical convection.
00:03:56:12 – 00:04:23:18
Speaker 1
So we’re into August now, mid August when you really have the peak, we’re entering the peak of the tropical the eastern. We’re entering the peak of the tropical Atlantic. Tropical season to talk to tropical there. Let’s ignore that. So when you have these big Saharan arrow breaks at last, this big one lasted more than a week.
00:04:23:27 – 00:04:54:24
Speaker 1
That suppresses the possibility of convection for quite some time. So, I wanted to show you some current imagery of that, but the, server for the Sims Tropical website has, crashed, so I can not show that. Show that to you. Did I have it? See, I guess I didn’t have it. No, I guess I didn’t have it loaded as a page.
00:04:54:24 – 00:05:20:09
Speaker 1
But if you if you go to the Sims satellite blog. There is, there are some, blog entries on the Saharan Air, outbreak that, can give you some information. My next topic is going to be Goes 14, Goes 14 is out of storage for the next two weeks. Two wings, one minute imagery. This is I’m going to play this again.
00:05:20:09 – 00:05:44:04
Speaker 1
This is might not be animating very clearly on your, over the go to meeting. But if you go to the Sims satellite blog, you’ll be able to see this. And, I really like this image because it shows, up over central Montana just how, dynamic the cirrus canopy is above convection. So goes 14 is up on top, goes 15 is on the bottom.
00:05:44:04 – 00:06:07:29
Speaker 1
The routine scanning scheduled for Goes 15. And this is going from 2345 to a little bit after one Z. And of course, between 0 and 1 Z, you have half hourly imagery because at zero three you’re scanning full disk. That takes 22 minutes. You get an image at 30 and C at oh 30, and then at oh 45 they’re doing some housekeeping on goes West.
00:06:07:29 – 00:06:49:03
Speaker 1
So there’s no scanning being done. So it really drives home the point that the routine scanning strategy for the operational goes west. You really miss a whole lot of interesting information that’s going on both at the cloud top, as shown in this satellite imagery. And at the, you know, at the surface as well. So I’m sure there are things going on over Pendleton that are, occurring on a time scale that you really can’t get good information at the operational 15 minute imagery of like 15 to 30 minute imagery from from Goes West.
00:06:49:06 – 00:07:26:02
Speaker 1
And the same thing is happening. That’s that’s the visible imagery. You can you can do the same thing with the infrared and up on top with the goes 14 a whole lot of, overshooting tops, temperatures changing on very short timescales that you just don’t see as the routine, scanning strategy. So this is a kind of an advertisement for Goes-r when Goes-r comes online, that those big gaps that occur now when we, when there are, full disks being scanned every three hours.
00:07:26:04 – 00:07:55:12
Speaker 1
So at the top of every three hours for goes west, those will occur anymore because goes higher will have the upper will have the ability to scan every five minutes that the Conus scale and every minute or 30s at the mesoscale simultaneously with the full disk scanning. So something to look forward to. In the next, let’s call it in the next five years goes our launches, in two or so years.
00:07:55:15 – 00:08:29:03
Speaker 1
And then it will come online. Goes-r will be it goes west and then goes s will become goes east if everything goes according to plan. Right now. One other thing that has been very interesting lately, are the fires that have been occurring in Idaho, and we have some imagery of that as well. So this is the, 3.9 micron from not last night, but from the night before.
00:08:29:05 – 00:09:02:04
Speaker 1
And again, this is the, one minute imagery just showing you the quick evolution of the fires over southwest Idaho. This is in the 3.9. So you’re seeing the hot the hot spots that develop and the also nice imagery of, nice visible imagery as well, showing, the development especially of pyro, cumulus. There have been some excellent examples of pyro cumulus so very strong cumulus nimbus development above the heat source of the fire.
00:09:02:12 – 00:09:33:12
Speaker 1
That’s an a new area of study here where they’re looking to see how that, how that, effect for, putting aerosols into the atmosphere and how that affects, How that affects the transport of aerosols, aerosols downstream. And you can see some nice pyro cumulus developing, over southwestern Idaho in this particular animation. And again, if you can’t see this through the go to meeting, go to meetings sometimes doesn’t do animations very well.
00:09:33:24 – 00:09:58:25
Speaker 1
You can certainly go to the Sims blog. So that’s just send us a C whiskey edu slash co slash blog. And look at that. And that’s, talked for a little over ten minutes and that’s, I think that’s, it for what I wanted to talk about. So goes 12 goes 14. And the Saharan air layer, are the topics for today.
00:09:58:25 – 00:10:04:14
Speaker 1
And if you have any questions, I’d be happy to entertain them.
00:10:04:16 – 00:10:17:13
Speaker 3
No, there’s really no questions. It’s just, you know, you know, some of the things that, you know, been informative and I think it’s kind of nice to get something that’s outside, you know, our forecast area just to see something that sounds fairly new. So that was very interesting. Thank you.
00:10:17:17 – 00:10:39:07
Speaker 1
And there is this, web page that I’m showing right now. If you go to the Sims blog, you can click through the different blog posts to this, and this will show you, the schedule. So here we have and today is 37, 85. Tomorrow is a little bit to the north. There’s some Gulf of Mexico convection.
00:10:39:07 – 00:10:59:23
Speaker 1
So it’s moving around. If you have, a reason for it being over your state. So if you want to go back over Idaho or back over Pendleton, you would email Tim Schmidt at NOAA or Steve Goodman at NOAA and make your case. And, maybe you’ll get one minute imagery and you can come to this website to look at the one minute imagery.
00:10:59:23 – 00:11:13:14
Speaker 1
So it’s it’s really hypnotizing. I could look at it all day. And the real problem is there’s just too much data. And, you know, you look at it for ten minutes and suddenly there’s ten more images to look at.
00:11:13:24 – 00:11:15:19
Speaker 3
This is great. Appreciate that. Thank you.
00:11:15:21 – 00:11:42:13
Speaker 1
Okay, Dan, I will hand it back to you. Okay. And I see, Jason Duncan has also joined us. Welcome. Jason. What office are you at? I work with the Hurricane Research Division. Oh, okay. Great. Out of Miami. Okay. Fantastic. All right. At this point, I’ll go ahead and turn it over to Bernie Connell here at, Sarah Bacon.
00:11:42:13 – 00:11:49:16
Speaker 1
I’ll just tell you that they are working on the survey here. I agree, we cannot wait to see it back up and running.
00:11:49:18 – 00:11:50:13
Speaker 2
And now.
00:11:52:13 – 00:11:59:11
Speaker 1
To the visit page. Okay.
00:11:59:13 – 00:12:10:18
Speaker 2
This will give me back to this is Bernie. And actually, with the dust, I had forgotten to send Dan a link, so I’m going to see if I can get to.
00:12:10:21 – 00:12:37:09
Speaker 2
A link that will show an example of the RGB of the dust. The one that chews for you. Matt sent. In. Because I know I put one up on our page. Last week. So let me see if I can pull this up now.
00:12:37:12 – 00:12:41:28
Speaker 2
So sorry about the slight delay. And then yesterday, do you have the. Can you.
00:12:42:00 – 00:12:42:19
Speaker 1
Get the one.
00:12:42:19 – 00:12:57:12
Speaker 2
There? Let’s see what. Otherwise, because this had, Okay.
00:12:57:15 – 00:13:44:11
Speaker 2
Well, why, that’s the one from yesterday. The PowerPoint points that right. While that’s coming up, hopefully it will come up. I thought I’d do a, Last month, we, reviewed a little bit about why you can see the hot fire is on the 3.9 micron. And today I saw it’s got back. Minor was going to show a little bit of some modest imagery and the hot spots he was saying, if you recall, on our goes, because in a WIPs we can only put eight bits worth of data in there, usually see the fire spots, trade at 330 K, with the ten bit data, we can see that go up to
00:13:44:17 – 00:14:11:26
Speaker 2
335 K. And if you can remember your conversions, 330 K is around 56 C. So when you’re looking at the fire hotspots in the 3.9 in the Gos imagery, you’ll see him saturate and they’ll say no data when it gets above like 54 C. This is hyperspectral data. Actually, once I grabbed it just to see what it would look like.
00:14:11:29 – 00:14:36:28
Speaker 2
And, the blue line here is just the background pixel. This is during the daytime. And this was back in May of 2007. So you can see actually what I have plotted here along the line that would be a plane curve. So this is in the ten micron region up here on the top. And then down here towards the left, you can see around four micron.
00:14:36:28 – 00:15:01:19
Speaker 2
You can see where the you have the background pixel. The blue here is real close to the plane. Curve for during the day. And but the fire pixel, the reason why we see it in the 3.9 is because we’re the satellite is sensing both the Earth emitted and the heat of the fire, and because it’s in a shorter wavelength than the instrument is more sensitive, it’s able to detect that.
00:15:01:19 – 00:15:25:09
Speaker 2
So that’s one of the reasons why we can just detect the hotspots. And this graph shows a little bit more of what we’re seeing. We see the Earth emitted curve here on the right, and the solar curve and the 3.9 sensors right down the center of the two of them. And so if we use the Planck curve and we convert them to a brightness temperature, these are what those two points would look like.
00:15:25:09 – 00:15:45:08
Speaker 2
The purple is the background pixel and the circle is the fire. And so just to to give you some reference, the satellite is up and colder temperatures is up as if you were looking at it, in the atmosphere are degrees C is warmer, is down near the bottom here on the Y axis, and colder is up near the top.
00:15:45:10 – 00:16:08:22
Speaker 2
So you can see that this for errors, which is hyperspectral, which has a 13 kilometer pixel for this particular fire. It was sensing like close to 80 degrees C, which is well above what we’re sensing with goes. And so I bring this up because when we go into the goes-r error will be able to sense pixels that are as warm as I think it was.
00:16:09:09 – 00:16:35:17
Speaker 2
400 K. And so, that will be an improvement on fire detection. The other thing I was going to bring up that, Dan had the link or did you bring that up here? This one. Okay. On that one. Okay. I don’t know if our other one came up, so I don’t know if I’ll be able to show picture of the RGV, but this was from when some of the big fire started in Idaho.
00:16:35:17 – 00:17:00:28
Speaker 2
And this is an, imagery, each hour. And Scott was showing some nice things. But here with the, rams are so be able to zoom in here. So because this has our 3.9, color table on it, if you’re not familiar with it, the white means it’s hot. And then as you get to the darker black colors, it’s cold.
00:17:00:28 – 00:17:32:26
Speaker 2
And then the, the greens are when it’s getting even colder and then, saturating on the cold in. So when oops, somehow I got it to go backwards. Let’s see if I can. Oh, I guess it’s rocking somehow I hit the wrong button. Okay, let’s just do that. Okay, now, if I started at the beginning of the loop at eight, it’s 18 UTC on the eighth when a lot of these fires in Idaho started.
00:17:33:08 – 00:17:49:28
Speaker 2
You can actually see a few here hot spots here and there. So I think some of these other fires are ones I wasn’t totally aware of that might have started a day or two earlier. And then as we get to later in the day in the ground around, it cools off. And I’d have to pull the time up here.
00:17:49:28 – 00:18:17:19
Speaker 2
We’re seeing this is at zero three UTC, so that’s, sunset or a little past sunset. And the important thing if you’re, and I’m at, one of the things you or you’re a firefighter, you want the fire to settle down at night with the cooler temperatures and the inversions. But as you can see, these pixels are pretty bright, and they continue to be, pretty bright through the night.
00:18:17:20 – 00:18:41:02
Speaker 2
And so, just from the satellite perspective, that’s not a good thing because these fires are not settling down. They’re pretty big. I don’t have a color table here that shows if it’s, saturating in the goes, but it is, pretty bright here. So, these fires are actually pretty hot. I had I don’t have it here, but I had looked at a motus imagery from nine UTC.
00:18:41:02 – 00:19:06:27
Speaker 2
That was Motus. Terra. So that was let me see. That would have been at about, what did I calculate 5 a.m. there time or something like that? And one of the motus pixels in 3.9 was 411 K, so that is about 138 C and 280°F. So that’s actually pretty hot fire for the middle of the night.
00:19:06:27 – 00:19:31:21
Speaker 2
So if you’re, even if you’re not a firefighter, I know when we had our fires close by last year, there were times when you woke up in the middle of the night and you could smell the smoke, and you’d look out your window, and it was just so clogged you couldn’t see anything. And I remember, one of the times we had a fire incident and I, we hadn’t been noticed that notified that there was a fire earlier in the day.
00:19:31:24 – 00:19:57:26
Speaker 2
And so being the geek I am as well, I pulled up my 3.9 imagery in the middle of the night and looked at it to see how close the fire was so that, so that I could have a heads up. It turned out that it was far enough away and we didn’t need to do anything in our homestead, but, but, that’s just some background information for, the general public too, as well.
00:19:57:28 – 00:19:59:17
Speaker 2
So.
00:19:59:20 – 00:20:08:28
Speaker 1
So can I ask Pendleton, do you get Motus data there, or are you limited to, just goes.
00:20:09:08 – 00:20:11:19
Speaker 3
Yeah. We usually use the internet for Motus data.
00:20:11:21 – 00:20:26:06
Speaker 1
Okay. Do you have a particular favorite website to, I mean, because you’re you’re you’re looking at multiple channels over the internet or just the visible.
00:20:26:08 – 00:20:52:03
Speaker 3
Yeah. Okay. Oh, yeah. One of our for Kansas is that he has it kind of set up on Google Earth to, to click on a website. I know there was one of them. I cannot think of exactly who it comes from, but I actually saw it came from, website of the Forest Service and it has active fire imagery, and it also has an archive date of Motus and I hope I had I cannot remember exactly who it is, but, that’s one I usually like to look at.
00:20:52:06 – 00:20:55:29
Speaker 1
Okay. I’m going to do a little googling, see if I can find it. I just fire.
00:20:55:29 – 00:21:01:27
Speaker 3
Imagery. I believe it is from the U.S. Forest Service.
00:21:02:00 – 00:21:38:16
Speaker 2
Yeah. And I do understand that they do do some, flight over, airplane flights with, infrared imagery that get a lot of the detailed information, too. But, this is something when that’s, not available and a fire is nearby. So helpful information. And then, of course, with the the visible imagery, you can look at it, early in the day or late in the day, depending upon where the, which satellite you’re looking at to get to help with, finding out where smoke plumes are so.
00:21:38:19 – 00:21:47:27
Speaker 1
Okay, I did find the U.S. Forest Service, and it looks like true color. I’m not seeing a lot of I’m not seeing 3.7.
00:21:48:00 – 00:21:50:28
Speaker 3
Yeah, I think that’s right. It is, true color on that. So,
00:21:51:00 – 00:22:13:27
Speaker 1
So not not that useful for nighttime. Okay. Oh, and I just wanted to mention, I’m not sure if you’re aware there is a Twitter feed for this. I’ve been tweeting, so if you follow that chat that, I’ve been putting up some links there for stuff we’ve talked about this morning.
00:22:14:00 – 00:22:16:26
Speaker 3
Oh, great. Well, let’s check it out. Okay.
00:22:16:28 – 00:22:26:24
Speaker 2
Yeah. And here it’s also listed at the top of the visit satellite chat page.
00:22:26:26 – 00:22:39:28
Speaker 2
Okay. And I don’t know, I guess this one didn’t come up here, but I could maybe try and do this if anybody is interested. And let me see if I can get a different link.
00:22:40:00 – 00:22:46:18
Speaker 2
It’s.
00:22:46:20 – 00:22:51:00
Speaker 2
Or we could end here and I could try this for the afternoon.
00:22:51:03 – 00:23:22:28
Speaker 1
I think maybe, just saying when the next one is the next satellite chart, which we haven’t talked about. Well, I’ll just propose. It’s, the 18th, I guess. Next. And if there are unusual weather events, we still do plan to have, satellite charts, kind of, on demand. So, the thinking was, if there’s a big tropical system, maybe we’ll have a satellite chart during that.
00:23:22:28 – 00:23:51:03
Speaker 1
And I did notice if you look in the northwest Caribbean right now, there is something there. So an area of disturbed weather, as they call it. So maybe late next week something will be in the Gulf of Mexico that would warrant a little bit of satellite chatting.
00:23:51:06 – 00:23:57:06
Speaker 1
But, that’s all. That’s all I have here. Dan, Bernie, do you have anything else to add?
00:23:57:19 – 00:24:08:03
Speaker 2
Nope. I got this running. Can you see it? Oops. Wait wait wait.
00:24:08:06 – 00:24:10:00
Speaker 1
So you’re looking at the South America?
00:24:10:02 – 00:24:13:23
Speaker 2
Well, yeah. I’m trying to get my list.
00:24:13:25 – 00:24:14:15
Speaker 1
Drag. Okay.
00:24:14:20 – 00:24:23:15
Speaker 2
Yeah. Okay, I’ll drag it over the other side. Yep.
00:24:23:17 – 00:24:30:24
Speaker 2
Well, I could try and do it this other way. It’s just that our list is so long. Hair.
00:24:33:27 – 00:24:48:29
Speaker 1
Why are you doing that? This is Jason. We have to plan some hurricane place possibly coming up for this this election. So thanks for, for interesting slide on effects. Okay. Thanks.
00:24:49:01 – 00:24:58:01
Speaker 2
Okay, this was some of the dust, and we can wait until later. If Pendleton need still to leave, we can do this this afternoon.
00:24:58:04 – 00:25:15:09
Speaker 3
Okay. Oh, No, I one of the things that happened is we did actually lose our network connection for a brief period of time. So, do you have something on the screen? It is, what I see. Is this your main website? Is there something that we, should be on the screen that we should be looking at, or do we miss connection?
00:25:16:11 – 00:25:17:09
Speaker 1
Sounds like they lost.
00:25:17:10 – 00:25:30:09
Speaker 2
Let’s see. I think you let me see the attendee list. You might have lost connection, because we do have. I stopped the loop, and right now we do have, an RGB image.
00:25:30:11 – 00:25:32:23
Speaker 3
Yeah, but, I mean, we’ve lost.
00:25:32:23 – 00:25:35:05
Speaker 2
Okay, so you can’t see it anyway. That’s fine. Thank you for.
00:25:35:05 – 00:25:43:11
Speaker 3
Everything. It was very informative. And, and so we’ll have to take on that Twitter page on the weather satellite chat. That’s pretty cool. Thank you very much.
00:25:43:14 – 00:25:46:05
Speaker 2
Okay. Thanks. Bye. Thank you for joining in.
