The blue and green colour small areas suggest this is a false color image that maps colours to a value and coincidentally looks like a fire.
Presumably it's measuring heat or something vaguely relevant but I don't trust my immediate visceral reaction to it.

- mturmon 2y agoThe image filename contains SWIR which is a clue. Several instruments can sense emissions in short-wave IR which light up for fires (and hot smoke plumes, and some industrial plants). E.g., VIIRS which is a successor to MODIS (https://www.earthdata.nasa.gov/data/instruments/viirs/viirs-i-band-375-m-active-fire-data https://www.earthdata.nasa.gov/data/instruments/viirs/viirs-...). The resolution in the posted image is much better than satellite, however. This implies that it's an airborne platform like FIRIS (https://wifire.ucsd.edu/firis-in-depth https://wifire.ucsd.edu/firis-in-depth). It also uses IR.
- martinpw 2y agoThe image has the label MAXAR at top right. I believe that company only does satellite imagery? Also articles that link to the image call it satellite data, eg: https://www.cnn.com/2025/01/08/us/video/images-fire-before-after-lcl-digvid https://www.cnn.com/2025/01/08/us/video/images-fire-before-a...
