High Resolution Precipitation Index - MSG - Indian Ocean

The High Resolution Precipitation Index (HPI) generation is based on the relationship between the channel top-of-atmosphere (TOA) radiance equivalent black body temperature (EBBT) of clouds and convective rainfall. The idea of this relationship is that clouds with cold tops are convective rain-bearing clouds. The scheme is a cloud indexing method based on the pixel values of an IR channel. It estimates an hourly accumulated precipitation. The final HPI product is sent to the UMARF once a day and stored. Applications and Users: Climate research by the WMO's Global Precipitation Climatology Project (GPCP). 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).
