Summary
Abstract: An all-India summer monsoon rainfall series for the instrumental
period of 1844-1991 has been constructed using a progressively
increasing station density to 1870, and one that is fixed thereafter
at a uniformly distributed 36 stations. The statistical scheme
accounts for the increasing variance contributed to the all-India
series by the increasing number of stations during the period
1844-1870. An interesting outcome of this study is that a reliable
estimate of summer monsoon rainfall over India can be obtained using
only 36 observations.
