  1. Observed climate data for South Asian region Jayashree Revadekar Centre for Climate Change Research Indian Institute of Tropical Meteorology Pashan, PUNE

  2. 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.

  3. Meteorological Parameters Precipitation Maximum Temperature Minimum Temperature Mean Temperature Relative Humidity Wind Pressure Sunshine SST and indices......................etc....

  4. Temporal Scale Annual Seasonal Monthly Weekly Pentad Daily Sub-daily

  5. Spatial Scale Station/grid Region Country Monsoon Asia Global ...etc

  6. Data Sources IITM IMD APHRODITE CPC CMAC CRU TRMM NCEP/NCAR NCDC
