Land surface temperature (LST) is a measure of the heating of the land surface and is distinct from air temperature. It is typically measured using remote sensing techniques such as thermal sensors on satellites. While LST can be affected by vegetation cover, it is not necessarily cooler than air temperature. Areas with high albedo and dense cloud cover may have lower LST due to reduced absorption of solar radiation, but this is not always the case. LST is typically higher than air temperature during the daytime, but may be lower at night.
