Abstract

This paper reviews the Indian geostationary meteorological satellite program - INSAT, which started in 1982. Successive improvements in meteorological payloads onboard the INSAT-series satellites, and their spatial and temporal resolutions are also highlighted. Currently, third generation of INSAT satellites - INSAT-3D and INSAT-3DR are in orbit and providing huge volume of data from their meteorological payloads. Imager payloads of both satellites are kept in staggered mode to provide new dataset at 15-minutes interval. Sounder payload onboard the INSAT-3D is declared its end of life in September 2020, and currently INSAT-3DR sounder provides useful data at hourly interval. In order to complete processing of these enormous data from INSAT-3D and INSAT-3DR satellites and their timely dissemination to users, Multi-mission Meteorological Data Receiving and Processing System (MMDRPS) was installed at the India Meteorological Department (IMD), New Delhi. Different imageries and geophysical products generated from the imagers and sounder along with their potential applications are also briefly discussed.
