Sample Information The TRMM Microwave Imager (TMI) detects the distribution and variability of sea surface temperature (SST) that occurs in tropical regions. It is the first microwave spacecraft sensor capable of accurately measuring SSTs through clouds. The orbit of the TRMM Observatory has an inclination of 35 degrees. As a result, the TMI instrument observes SST between 35 degrees South latitude and 35 degrees North latitude. The TRMM orbit causes the local overpass time to drift over the entire 24 hours of a day approximately once each month, enabling observation of regional diurnal SST variations.
The provided products show the Monthly SST measurements that result from seasonal and either El Niño- or La Niña-influenced storm/weather conditions. The El Niño sample shows warmer than normal waters of the eastern equatorial Pacific Ocean, and cooler than normal in the western equatorial Pacific Ocean. but the La Niña sample shows considerable rainfall over Ceylon, Indonesia, the Phillipines, and Australia.
"TRMM satellite products, Version 5, represent the second publicly-released dataset from the TRMM mission. They are NOT perfect, but were judged good enough to be of value to the general user community. Some products have known deficiencies, while others may not yet have been tested as thoroughly as one would wish. In order to effectively communicate the known problems at the time of the initial data release (Sept. 1, 1998), as well as future problems that may still be uncovered, the TRMM project will make this information available via the TRMM Web site at http://trmm.gsfc.nasa.gov/data_dir/ProductStatus.html."
