Description |
Aqua AMSR-E derived soil moisture data (L3- product) over India available during the period 2002-2005 were analysed along with limited ground truth data in terms of soil moisture and rainfall. It has been observed that AMSR-E derived soil moisture in arid region (desert area) over estimates by 4%. About 2% underestimation of soil moisture was obtained at another test site with agriculture practices. By comparing estimated soil moisture and rainfall data, we found that estimated soil moisture varies well with rainfall for uniform bare fields. The heavy rainfall events in several parts of India that lead to flooding were clearly seen through soil moisture maps of 4 years. Drought situation in 2002 was also observed through soil moisture maps. The soil moisture retrieval accuracy depends on inhomogeneity in a resolution cell. |
