It sounds like they (LE units headed for Tahoe Basin) just got turned around trying to go up 50 and were rerouted out 80 and around.

1630 IR flight, east end of the fire. This footprint is noticeably smaller in a few places than the 3pm VIIRS flight, suggesting significant plume-related errors with the VIIRS pass:

@mjacobs and for all of you looking at VIIRS, MODIS, GOES please take a moment to learn/understand the spatial resolution of these sensors.

And also realize that these satellites wobble a little tiny bit. But the lever arm from a satellite is gigantic. I don’t know the exact numbers they differ based on the optics but it is like 1/100 of degree error in measurement of the attitude of a satellite can put a pixel a mile off.
It’s a whole bunch of hard work (not a miracle) that make the spots come even close to where they belong. And don’t forget that you need a good earth surface model to project the spots on.

That should help you be cautious in your interpretation of satellite hot spots.

Satellite hot spots are interpretational. They are good indicative tools. Anyone who works with these mapping sources should know that. Having said that…anyone who reads them should know that as well.

For import into CalTopo, Google Earth, etc. Can’t vouch for how accurate they keep the data vs what’s really on the ground.
