Abstract :
Aqua AMSR-E L3-daily soil moisture data of 7 years (2002-2008) were analyzed to know the soil moisture pattern over entire India and also some specific areas with limited ground-truth. The data were also used for observing change in daily soil moisture over some parts of Gujarat and Rajasthan. By comparing estimated soil moisture and rainfall data we found that the estimated soil moisture varies well with rainfall for uniform bare fields. The results indicate that the soil moisture can be used for drought monitoring and flood area estimation with less accuracy.
