New Satellite Section in OK-FIRE Announced

The "Satellite Maps" section in "Current Maps" (the second left-hand menu item) has been recently redesigned with new maps and links to animations over the past four hours.  Only the most useful maps to wildland fire managers are included in this section.  With the new GOES-16 satellite, we now have the luxury of 5-minute updates of satellite imagery utilizing various wavelength bands. The organization of this new satellite map section is described below.

Each row in the first four rows has a statewide ("Oklahoma") map first, followed by a zoomed-in map called "Oklahoma West" and another zoomed-in map called "Oklahoma East".  After the fourth row are "Regional" maps for each of the four different wavelength bands.

The first row contains the maps which use the 3.9 micron wavelength, which is the most useful wavelength to detect hot spots such as wildfires.  These maps have 2-km resolution.  We also, for easy access, have a direct link to this map in the left menu section of OK-FIRE. 

In the second row are the "Visible (Blue)" maps which are good at detecting smoke plumes (much better than in the red wavelength band).  These maps have 1-km resolution. 

In the third row are the traditional visible maps, "Visible (Red)", with their greater 0.5 km resolution and ability to clearly show surface features and clouds. 

In the fourth row are "Water Vapor" maps using the lower-level water vapor channel (about 10,000 feet elevation) at 2 km resolution. 

Under each map is an educational text description (also found in the "Learn More"
links) in which we describe the utility of each map to wildland fire managers as well as list its spatial resolution and central wavelength.  There is also a link to an animation of that map over the past four hours from the College of DuPage (COD) website.  This animation comes up in a separate tab in your browser.  This COD website is incredibly useful: you can select a past animation period in the "Choose Number of Frames" left menu area (up to 200 frames or 16.7 hours), the wavelength band of the map you wish to see ("Select a Product"), and any number of different geographical sectors ("Select a Sector Category").  Also within the explanatory text under each map in Satellite Maps is a link to a fact sheet describing the particular uses of the wavelength band being used in that specific map.


Useful Note:  When you initially click on any map in the Satellite Maps section, you can make it full screen (on most browsers) by right clicking on the map and selecting "View Image" (in Firefox) or "Open image in new tab" (in Chrome).  After that, you can use the magnifying glass icon which appears on the map to zoom in even further.
