Air temperatures are scorching hot, with temperatures in the high 90&#8217;s and low 100&#8217;s. An amplified upper-level ridge has been quite persistent over the PNW, bringing the high temperatures and dry air to the area.<\/p>\n<p>Due to the <a href=\"http:\/\/droughtmonitor.unl.edu\/Home\/RegionalDroughtMonitor.aspx?west\">abnormally dry conditions<\/a>, fires have been initiated and are scattered within the PNW. Fires can be seen below via two polar products: the Day\/Night Band (DNB, 0.7um) and the Imagery Band 4 (I-4, 3.74um). The two products work in complement with one another. The DNB assists in utilizing a sun\/moon reflectance model that illuminates atmospheric features, senses emitted lights, and assists with cloud monitoring during the nighttime, while the I-4 band senses the &#8216;fire hotspots&#8217;, areas that exude high brightness temperatures in comparison to the nearby environment. The I-4 band also assists the DNB in differentiating between what emitted lights are city lights, and what lights are the emitted lights from the fires.<\/p>\n<p>It is important to note that the DNB and I-4 band are at two different spatial resolutions; DNB at 750 meters an the I-4 band at 375 meters. The static images can be seen below at 0924Z (0224 local time), 3 August 2017.<\/p>\n<p><span style=\"text-decoration: underline\">DNB<\/span><\/p>\n<p><span style=\"text-decoration: underline\"><a href=\"https:\/\/rammb2.cira.colostate.edu\/visit-blog\/wp-content\/uploads\/sites\/5\/2017\/08\/DNB_modified.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1759\" src=\"http:\/\/rammb.cira.colostate.edu\/training\/visit\/blog\/wp-content\/uploads\/2017\/08\/DNB_modified-1024x623.png\" alt=\"DNB_modified\" width=\"640\" height=\"389\" \/><\/a><\/span><\/p>\n<p><span style=\"text-decoration: underline\">I-4 Band<\/span><\/p>\n<p><a href=\"https:\/\/rammb2.cira.colostate.edu\/visit-blog\/wp-content\/uploads\/sites\/5\/2017\/08\/I4_modified.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1760\" src=\"http:\/\/rammb.cira.colostate.edu\/training\/visit\/blog\/wp-content\/uploads\/2017\/08\/I4_modified-1024x623.png\" alt=\"I4_modified\" width=\"640\" height=\"389\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Pacific Northwest (PNW), that is, the states of Washington, Oregon, Idaho and Western Montana are experiencing a significant heat wave right now.
