TRMM MICROWAVE IMAGER (TMI) WENTZ OCEAN PRODUCTS V3

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Catalog Last Checked: May 18, 2026 at 02:59 PM | Dataset Last Updated: May 11, 2026
The TRMM Microwave Imager (TMI) Wentz Ocean Products dataset used the TRMM Microwave Imager (TMI), which is a 5-channel, dual-polarized, passive microwave radiometer. The TMI is used to measure several important meteorological parameters over sea surfaces, such as precipitation rate, wind speed, wapter vapor, and sea surface temperature. The TMI, a successor to the SSM/I, measures radiation at frequencies of 10.7, 19.4, 21.3, 37, 85.5 GHz. It orbits at an altitude of 218 miles, much lower than the SSM/I, thus providing better resolution.
