The program, Hydro-4M, "Hydro-Meteorological studies with Multi-satellite sensors and Multidimensional approaches at Mongolian Grassland," aims to obtain better understandings of hydrometeorology of grassland in northeastern Asia by using satellite remote sensing, land-surface models, and land data assimilation.

In order to obtain necessary data for this goal, 6 automatic weather stations (AWS) and 12 automatic soil moisture & temperature measurement systems are placed in Mongolian grassland. The data obtained at these AWS are used to validate and calibrate satellite soil moisture products such as that of AMSR2 (Advanced Microwave Scanning Radiometer 2) on board GCOM-W (Global Change Observation Mission-Water) and L-band Synthetic Aperture Radar on board of ALOS2 (Advanced Land Observing Satellite-2), and also to force land surface models to predict land surface state of the Mongolian grassland.

The project Hydro-4M is led by Dr. Jun Asanuma at Center for Research in Isotopes and Environmental Dynamics, University of Tsukuba, Japan, and funded by Japan Aerospace Exploration Agency (JAXA) and Japan Science Promotion Society (JSPS).
