- The network density for the estimation of areal rainfall is determined by the method of optimum estimation. This method considers local variations as well as inter-station characteristics of rainfall over an area while assigning weights to gauges for the estimation of areal rainfall. The network density required for different tolerable errors in the estimation of areal rainfall for the months June-September, for the monsoon season, and for the year, was determined for different sized areas over Vidarbha, a meteorological subdivision of India. The errors in estimations of areal rainfall obtained by the method of optimum estimation are smaller than those obtained by the arithmetic mean.
