[edit] Summary
http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=3332
NASA’s new Moderate-resolution Imaging Spectroradiometer (MODIS) allows scientists to gauge our planet's metabolism on an almost daily basis. GPP, gross primary production, is the technical term for plant photosynthesis. This composite image over the continental United States, acquired during the period March 26–April 10, 2000, shows regions where plants were more or less productive—i.e., where they “inhaled” carbon dioxide and then used the carbon from photosynthesis to build new plant structures.
