Wait, so at 28k/km the temp goes up to 15C?

This is all very cool but this temperature reading caught my eye as unexpected.

I found that surprising too! This probably isn't a completely accurate number, as the sensor is black and likely experienced some heating from the sun. Something also worth noting is that different layers of the atmosphere experience different temperatures www.noaa.gov/jetstream/atmosphere/layers-of-atmosphere

Amazing. I love that i didn't know this. When i was studying weather as part of my pilots license i noted the basic mental math that i'd lose ~2 degrees celsius per 1000ft, but never did i take a second to ask, what happens when i go up 28,000 km.

the article says 28.42 km. where are you seeing 28000 km ?

yeah i have no idea why my brain decided to type that (twice...), its clearly 28km
