The drought study is mainly based on the observation of precipitation, temperature and soil moisture, such as various drought index and moisture index. The satellite products have not been widely used because of lack of capacity building in many Asian countries. Under the support of Japan Aerospace Exploration Agency (JAXA) and Tokyo University, the retrieved soil moisture dataset from satellite remote sensing products will be used in this project, and the respective collaborators will validate this data set by using the in-situ observation of soil moisture, precipitation and temperature. The AWCI/GEOSS will coordinate this regional activity, along with the flood and water quality groups.
