Multi-Source Hydrological Data Products to Monitor High Asian River Basins and Regional Water Security

This project explored the integrated use of satellite, ground observations and hydrological distributed models to support water resources assessment monitoring in High Mountain Asia (HMA). Hydrological data products were generated taking advantage synergies European Chinese assets space-borne observation systems. Energy-budget-based glacier mass balance driven by satellite developed. These can be applied describe glacier-melt contribution river flow. Satellite used for forcing, calibration, validation assimilation basin models. A pilot study was carried out on Red River basin. Multiple using collected satellites. new Evapo-Transpiration (ET) dataset from 2000 2018 generated, including plant transpiration, soil evaporation, rainfall interception loss, snow/ice sublimation open evaporation. Higher resolution characterize glaciers their response environmental forcing. studies focused Parlung Zangbo Basin, where facies mapped with GaoFeng (GF), Sentinal-2/Multi-Spectral Imager (S2/MSI) Landsat8/Operational Land (L8/OLI) data. The geodetic estimated between 2017 Zi-Yuan (ZY)-3 Stereo Images SRTM DEM. Surface velocity studied Landsat5/Thematic Mapper (L5/TM), L8/OLI S2/MSI over period 2013–2019. An updated method developed improve retrieval albedo correcting reflectance anisotropy, a 2001–2020. detailed energy model field experiments at No. 4 Glacier 24 K Glacier, both Tibetan Plateau. Besides meteorological measurements, included glaciological measurements. formulated terms enthalpy easier treatment phase transitions. assess spatial variability melt. In accumulated melt 1.5 2.5 m w.e. accumulation zone 4.5 6.0 ablation zone, reaching 6.5 terminus. seasonality observed combining intensive campaigns continuous automatic observations. linkage snowpack analyzed Chiese (Italy) Heihe (China) basins developing applying retrievals multiple ways. FEST-WEB calibrated Temperature (LST) map properties. watershed coupling ecohydrological socioeconomic Integrated modeling is supported an parallelized system. latter exploits brightness temperature (Advanced Microwave Scanning Radiometer, AMSR), LST (Moderate Resolution Imaging Spectroradiometer, MODIS), precipitation (Tropical Rainfall Measuring Mission (TRMM) FengYun (FY)-2D) in-situ case algorithm has been disaggregate SMOS (Soil Moisture Ocean Salinity) moisture making correlation evaporative fraction moisture.
