CEOP_AP Mongolia Reference Site BTS Station

To develop and verify algorithms for satellite remotesensing of soil moisture by microwave radiometers "AMSR" and "AMSR-E", soil moisture conditions and related meteorological/hydrological factors are being monitored by automatic stations spread in the Mongolian Plateau, where high quality data are expected to be obtained because of relatively uniform ground-surface-conditions.

Station Operator:

These data are obtained under the framework of JAXA-JRA "Ground Truth for Evaluation of Soil Moisture and Geophysical/Vegetation parameters Related to Ground Surface Conditions with AMSR and GLI in the Mongolian Plateau" (PI : Prof. I. Kaihotsu, Hiroshima Univ.) and is partnership with Institute of Meteorology and Hydrology, Ministry of Nature and Environment, Mongolia.
