Cloud Motion Vector Imd
Altitude is assigned based on a temperaturepressure derived from radiative transfer calculations in the environment of the target.
Cloud motion vector imd. Presently goes cloud motion vector heights are assigned by any of three techniques when the appropriate spectral radiance measurements are available. Cloud motion vectors cmv are derived for three layers namely lower middle and upper troposphere using three half hourly images 2330 utc 0000 utc and 0030 utc for the 0000 utc observation through a detailed pattern matching technique. In opaque clouds infrared window irw brightness temperatures are compared to forecast temperature profiles to infer the level of best agreement that is taken to be the level of the cloud. Imd cloud management tool.
These include source programs for rainfall estimation sea surface temperature retrieval vegetation index retrieval clouds classification cloud motion vector visible and infra red water vapor winds. Operational in the month of october 2002 imd began deriving cloud motion vectors cmv from the infrared data twice a day from the triplets at 2330 0000 and 0030 utc and 0700 0730 and 0800 utc. Centre of the tropical cyclone. Confidence in the centre position.
From kalpana 1 satellite at imd ak mitra ak sharma rc bhatia rk giri and vr rao satmet division india meteorological department new delhiindia abstract the cloud motion vector cmv is one of important meteorological products derived from satellite data and is known that it has a positive or neutral impact on global or middle scale. The centre of the cloud eye or if not discernible of the wind pressure centre. Noaanesdis intends to provide noaa goes versions of scientific algorithms and programs for operational implementation at imd.
