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 sea surface temperature maps are based on observations by the MODIS sensors on NASA's Terra and Aqua satellites. The satellites measure the temperature of the top millimeter of the ocean surface. In this map, the coolest waters appear in blue (approximately -2 degrees Celsius), and the warmest temperatures appear in pink-yellow (35 degrees Celsius). Landmasses and the large area of sea ice around Antarctica appear in shades of gray, indicating no data were collected.
