General Overview

GMS-5 satellite images are taken over the Tropical Western Pacific (TWP), over each of the TWP sites. The raw data are downlinked to the SeaSpace Corp. receiving station at the University of Hawaii. The GMS-5 was launched in March 1995 into a geostationary orbit above 0°N, 140°E. It carries a Visible and Infrared Spin Scan Radiometer (VISSR) with four channels, one in the visible part of the spectrum and three in the infrared. The ground resolution at the subsatellite point is 1.25 km in the visible channel and 5 km in the infrared.
