What is the difference between “surface/land temperature” and uh temperature?

309 views

While I’ve wondered about it before with the temps in Siberia, right now I’m specifically talking about [this heat map](https://i.imgur.com/8dxxZ57.png) of India.

The grey parts are over 140 F but it’s land temp. It can’t really be a “feels like” temp of 140F there, can it? What does that mean for air temp? I assume it might affect farming (if seeds are in dirt hotter than they want I imagine that will be a problem).

I also imagine surface/land temp is different than air(?) temp. But most people understand air(?) temp, what’s the point of these land temp heat maps? I see them a lot lately but I never really see any explanation of the difference.

(or maybe I really am the only person who doesn’t understand the difference. I also wasn’t sure which flair to choose.)

Thanks!

The temperature you see reported in weather reports is taken in the air, at a standardized height off the ground, in the shade. In general, the ground on a hot, sunny day can be considerably hotter than that temperature, but in a way that is much harder to standardize for record-keeping and reporting purposes (because it depends on things like how the surface is oriented and what color it is).
