EARTH SCIENCE > LAND SURFACE > SURFACE THERMAL PROPERTIES > LAND SURFACE TEMPERATURE
Refers to how hot the ?surface? of the Earth would feel to the touch in a particular location. From a satellite?s point of view, the ?surface? is whatever it sees when it looks through the atmosphere to the ground. It could be snow and ice, the grass on a lawn, the roof of a building, or the leaves in the canopy of a forest. Thus, land surface temperature is not the same as the air temperature that is included in the daily weather report.
