Observed Rainfall And CMIP6 Data

The gridded rainfall datasets used in this analysis were sourced from the Indian Meteorological Department (IMD). These datasets were collected on a daily basis from 1951 to 2021 and were obtained from the National Climate Centre (NCC) of IMD from the following URL: https://www.imdpune.gov.in/lrfindex.php. The dataset covers the Indian River Basins (IRBs) and has been generated at high resolution by assimilating data from 6955 rain gauge stations spread across the IRBs. For the simulated daily precipitation spanning the years 2021 to 2100, four different Shared Socioeconomic Pathways (SSPs) were considered: SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5. The simulated precipitation outputs were derived from the Coupled Model Intercomparison Project-6 (CMIP6) and were obtained from the following URL: https://esgf-node.llnl.gov/search/cmip6/. All 12 models of CMIP6 were downloaded, specifically using the variant label r1i1p1f1 as an initial condition.
