Observed climate data for South Asian region Jayashree Revadekar Centre for Climate Change Research Indian Institute of Tropical Meteorology Pashan, PUNE
It is most important that any model simulated data be used only after prior evaluation of the model’s skills and reliability based on comparisons with the observations.

Southern Asia Daily Rainfall Estimate
ftp://ftp.cpc.ncep.noaa.gov/fews/S.Asia/
Daily rainfall estimation for southern Asia domain (70-110E;5-35N) beginning May 01, 2001.
High Resolution 0.1 by 0.1 degree This product is updated three times daily at around 9am, 1pm, and 9pm Eastern Local Time and covers a 24 hour period of accumulated precipitation. Inputs include Global Telecommunication System (GTS) station data, as well as geostationary infrared cloud top temperature fields and polar orbiting satellite precipitation estimate data from SSM/I and AMSU-B microwave sensors.
