All India rainfall is an areal average of 29 subdivisional rainfalls. Subdivisonal rainfalls are from areally averaged district rainfalls. The district rainfall is computed from averaging all stations in the district. Rainfall amounts (in millimeters) are totals for June, July, August, and September.

The data is consistent from 1871 - 1990 in that it is constructed from a 306 station network, with no missing data. The number and distribution of stations for 1991 - 2000 is unknown.
