Which products are being derived from operational Indian Geostationary Meteorological Satellites?
A. The following products are being derived from INSAT satellites Outgoing Longwave radiation (OLR) Sea surface temperature (SST) Quantitative precipitation estimate (QPE) Cloud Motion vectors (CMV) Water Vapour Wind (WVW) Cloud Top Temperature (CTT) Visible Channel Image Infrared Channel Image Colour Composite Channel Image Water vapour Channel Image Outgoing long wave radiation (OLR) Majority of meteorological sensors operate in long wave range of radiation so that: 1. They operate day and night 2. The problem of low albedo is not encountered 3. The earth radiation is maximum and thermal IR and ocean emissive is nearly unity. Keeping the above into mind the outgoing flux of long wave radiation at the top of atmosphere is an important parameter in the earth atmosphere radiation budget. This parameter can be derived by physical/statistical algorithm from the narrow band. Sea Surface Temperature (SST): As we know oceans are the major storage of heat in the earth climate systems.
