Land surface temperature is 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, or the roof of a building. These maps compare daytime land surface temperatures in a particular month to the average temperatures for that month from 2000-2008. Places that were warmer than average are red, places that were near normal are white, and places that were cooler than average are blue. The observations were collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.
The rainfall maps show total monthly rainfall in millimeters as recorded by NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite. High rain totals are represented in dark blue, while small rainfall totals are shown in white. TRMM measures rainfall in the tropics. High-latitude regions, where TRMM does not record rainfall, are gray.
