The National Centre for Medium Range Weather Forecasting (NCMRWF) is a Centre of Excellence in Weather and Climate Modelling under the Ministry of Earth Sciences. The mission of the Centre is to continuously develop advanced numerical weather prediction systems, with increased reliability and accuracy over India and neighboring regions through research, development and demonstration of new and novel applications, maintaining the highest level of knowledge, skills and technical bases. This data web portal contains (1) IMDAA Data - high resolution (12km, 1-hourly) regional reanalysis over India, from 1979 to 2018 (Extended upto December 2020) and (2) NGFS Data - high resolution (25km, 6-hourly) Global reanalysis, from 1999 to 2018. For the continuity of the IMDAA regional reanalysis dataset beyond 31 December 2020, NCMRWF is releasing IMDAA-Like products derived from the operational NCMRWF Unified Model (NCUM) global NWP system of 12 km resolution. Unlike IMDAA reanalysis products, a few of the IMDAA-Like products are only available at 3 hourly intervals. Multi-level IMDAA-Like products are available only at 18 pressure levels.
