The IMD gridded rainfall data is available from 1901-2022 https://www.imdpune.gov.in/cmpg/Griddata/Rainfall_25_NetCDF.html <https://mailtrack.io/trace/link/b238ccfa64f789701a1ca7af3b54a5e3e24d7dcd?url=https%3A%2F%2Fwww.imdpune.gov.in%2Fcmpg%2FGriddata%2FRainfall_25_NetCDF.html&userId=8747767&signature=ce9e45137af369df>
There's a python package 'imdlib' to read and convert this data to XArray. I have used this in the past to process the data. https://github.com/spatialthoughts/projects/blob/master/imd/imd_annual_average.ipynb <https://mailtrack.io/trace/link/ac0912ca419d6e7594c567ca44e4d94d2efdf8a5?url=https%3A%2F%2Fgithub.com%2Fspatialthoughts%2Fprojects%2Fblob%2Fmaster%2Fimd%2Fimd_annual_average.ipynb&userId=8747767&signature=b02d82c756801e30> You can use this to easily compute LPA and anomalies.
