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.
These maps show net primary productivity, which is how much carbon dioxide vegetation takes in during photosynthesis minus how much carbon dioxide the plants release during respiration (metabolizing sugars and starches for energy) or decay. The data come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Values range from near 0 grams of carbon per square meter per day (tan) to 6.5 grams per square meter per day (dark green). A negative value means decomposition or respiration overpowered carbon absorption; more carbon was released to the atmosphere than the plants took in.
