摘要：
In this study, the potential of Kalpana-1 derived rainfall product is assessed for drought monitoring over India at the meteorological sub-division scale. A preliminary analysis is done for the anomalous south-west monsoon season of 2009 using two drought indices: percent of normal and Standardized Precipitation Index. A considerable difference between these two indices is observed even from the same rainfall data. The severe drought condition over most parts of India during June is not well captured by Kalpana-1 derived rainfall data. Additionally, due to underestimation of orographic rainfall by Kalpana-1 derived product, the meteorological sub-divisions located over these regions showed extreme drought condition throughout the season.
