Global Instability Lifted-Index - MSG - Indian Ocean

Description

The GII product consists of a set of indices which describe atmospheric air mass instability in cloud free areas. These indices are highly empirical in nature and might even be only relevant in certain geographic regions or under certain circumstances. The algorithm is a physical retrieval scheme developed at EUMETSAT. Applications and Users: Nowcasting and short term forecasting (up to 12 hours). Resolution is 3x3 pixels. Lifted-Index is one of the four common instability indices included in GII, and it is defined as follows: Lifted-Index = T(ambient at 500hPa) – T(parcel lifted to 500hPa)” Where T is the air temperature at the indicated levels From 1 June 2022, Meteosat-9 at 45.5° E is the prime satellite for the IODC service, replacing Meteosat-8 (located at 41.5° E while in operation).
