MODIS Surface Reflectance. This true color image over North America was produced from the MODIS Land Surface Reflectance data product.

Sea Surface Temperature and Vegetation Index from MODIS. This is a composite MODIS image showing the "green wave" of spring in North America and sea surface temperature in the ocean.

Night lights. This is a low light image capture of the United States cities at night. It is actually a composite of over 200 images made by satellites orbiting the Earth. Scans were made by the USAF Defense Meteorological Satellite Program (DMSP) Operational Linescan System. The DMSP satellites continue to help in the understanding and prediction of weather phenomena as well as provide key information about population patterns, city light levels, and even rural forest fires.
