Climatological and Historical Information
Regional or Subdivisional Rainfall Climatologies
Based on subdivisional data from the Indian Institute of Tropical Meteorology (IITM).
These are spatial maps showing annual, seasonal, and monthly climatologies of total rainfall amounts for each region/subdivision.
Regional or Subdivisional Rainfall Anomalies
Based on subdivisional data from the Indian Institute of Tropical Meteorology (IITM).
These are spatial maps showing rainfall anomalies for each region/subdivision, expressed as a percentage difference from normal. Choose from annual or seasonal anomalies for individual years between 1871 and 2000.

Regional or Subdivisional Rainfall Anomaly Timeseries
Based on subdivisional data from the Indian Institute of Tropical Meteorology (IITM).
These are time series of annual and seasonal rainfall anomalies (expressed as a percentage difference from normal) for each region/subdivision.

Daily Rainfall Climatology
Based on station data from 1901-1970. Daily climatologies of total rainfall (mm/day) are presented for stations with more than 25 years of data. See animations showing the evolution of the climatological monsoon season!

Single Season Animations of Daily Rainfall
Based on station data from 1901-1970. Animations of daily total rainfall (mm/day) for the May-September period
are presented for each year in the dataset. A great way to visualize the evolution of a particular monsoon season.
