Key Eco-Hydrological Parameters Retrieval and Land Data Assimilation System Development in a Typical Inland River Basin of China's Arid Region- Final Results
During Dragon 2 period, fruitful results have been achieved with regard to the estimation of land surface parameters and the development of a catchment scale land data assimilation system in the Heihe River Basin (HRB), China. By using multi-platforms (satellite, aircraft, crane-based, ground station etc.), various observation results have been obtained, paving the way for carrying out a variety of dedicated and novel retrieval investigations related to eco-hydrological parameters, e.g. precipitation, snow properties, soil moisture (SM), land surface temperature (LST), evapotranspiration (ET), canopy resistance, leaf chlorophyll content, bi-directional reflectance, albedo. In addition, the Heihe data assimilation system has been developed to make use of these multi-source observations at the catchment scale, in order to improve the estimation of SM, soil temperature, ET, snow and streamflow at 1 km spatial resolution with a temporal resolution of 1 hour.
