The National Centre for Medium Range Weather Forecasting (NCMRWF), India - Reanalysis Data Service (RDS) portal contains (1) IMDAA Data - high resolution (12km, 1-hourly) regional reanalysis over India, from 1979 to 2018 and (2) NGFS Data - high resolution (25km, 6-hourly) Global reanalysis (1999 to 2018).
A reanalysis is a high-quality climate-data product produced by assimilating long time series of observations with a consistent and state-of-the-art numerical weather prediction (NWP) model and data assimilation (DA) system to represent the best estimate of the state of the atmosphere.
The reanalysis will produce a consistent data set of high‐resolution fields for a wide range of atmospheric variables available from 1979 to 2018 (satellite era). Data Web Portal website release Version (0.2), we welcome users to register and access the IMDAA & NGFS reanalysis datasets.
25 Μαρ 2018 · The IMDAA reanalysis will be a useful tool for increasing our understanding of the monsoon, how it has changed over the past four decades and provides scientists with a better framework to understand future monsoon trends.
• Reanalyses provide comprehensive snapshots of atmospheric conditions at regular grids and intervals over long time periods; whereas observation alone can provide only a limited understanding of the past weather and climate. Aims and uses of Reanalysis.
