摘要：

Available climatic observation data are very limited in Qinghai-Tibetan Plateau (QTP) because of its severe physical environment. Great efforts have been made to assimilate remote sensing data and in situ observation data to produce qualified datasets. This study has verified the applicability of a ground meteorological forcing dataset named CMFD in a typical site (TGL) and a typical region (XKL) in QTP by the simulation of water-heat processes with land surface model (LSM). Results show that Noah LSM simulation with CMFD-derived forcing data can accurately present the water-heat conditions of individual site as well as typical region on QTP with an NSE of 0.818 for TGL site and mean annual ground temperature discrepancy less than 1 degree compared with observation data of 8 boreholes in the total 10 boreholes in XKL. It is proved that CMFD dataset can be used as reliable data source for simulation applications on QTP.
