Smoky skies over Canada and the U.S.

Over the past few weeks, fires have erupted and spewed high concentrations of smoke over western Canada and the United States. To exacerbate the situation, more fires initiated recently in the western U.S. National Weather Service (NWS) Weather Forecast Offices (WFO) highlighted the High-Resolution Rapid Refresh (HRRR) – Smoke products on social media to warn Continue Reading

Tropical Activity in the East Pacific

It is that time of year again! The time of year where tropical storms, hurricanes initiate and permeate through the Atlantic and the East Pacific Oceans. Currently, a few to note are tropical depression Greg, Tropical Storm Irwin and Hurricane Hilary. A screenshot of the National Hurricane Center’s  (NHC) ‘Active Storm’ Map showing the relative Continue Reading

MODIS Longwave channel difference of Gulf Stream and Labrador currents

Jeff Braun and Louie Grasso Figures 1-4 show Modis images at 3.9, 8.53, 11.02, and 12.03 µm, respectively at 1825 UTC on 6 April 2010. Off the east coast of the United States, two ocean currents are evident in the imagery: The cool, southward flowing, Labrador current and the warm, northerly flowing, Gulf Stream. All Continue Reading

GOES-R Proving Ground At the Great Lakes

Louie Grasso, Dan Lindsey, J. Braun GOES-R ABI will have several channels in the window region from which channel difference products can be produced. Three of the channels, 8.53, 11.02, and 12.03 µm are available from MODIS. From these three channels, three channel differences can be produced. In this example, one of the channel differences Continue Reading

“California Burnin’ on Such a Summers Day”

(Courtesy NASA/MODIS/TERRA – July 26, 2008) Jeff Braun Currently, California has 26 fire incidents…mostly across the northern half of the state.  Fourteen of these fires are considered large at the moment (= or > 100 acres…see following map). To date (this fire season – through July 30, 2008), over 750,000 acres of California have burned. Continue Reading

Fires in Russia = Smoke in Minnesota

Jeff Braun Many large fires in southern/southeastern Russia have choked the skies with smoke. This image (first image) of the fires (locations outlined in red) was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite late last week (April 17, 2008). Most of these fires are  agricultural fires set by people, much as we do Continue Reading
