High-resolution, gridded daily rainfall over India from the India Meteorology Department To fulfill the demand from the research community, a high resolution (10 X 10 Lat/Long) gridded daily rainfall data set for the Indian region was developed. For the analysis, daily rainfall data of 6329 stations were considered. However, there were only 1803 stations with a minimum 90% data availability during the analysis period (1951-2003). We have used only those 1803 stations for interpolation in order to minimize the risk of generating temporal inhomogeneities in the data set due to varying station densities. The geographical area, 6.50 N to 37.50 N, 66.50E to 101.50 E was considered for interpolating the station rainfall data. For the analysis, we have followed the interpolation method proposed by Shepard (1968). This method is based on the weights calculated from the distance between the station and the grid point and also the directional effects. Standard quality controls were performed before carrying out the interpolation analysis.
