| Summary: | A High spatial and temporal Resolution (5×5 km, 1 hour) land-atmospherical Assimilation Dataset of Qinghai-Tibetan Plateau (QTP-HRAD)from 2010 to 2020is generated and produced by the Weather Research and Forecasting (WRF) model version 4.2.2 and the three-dimensional variation (3DVAR) module. The NCEP_ADP data are assimilated in the WRF model, which include radiosonde and aircraft reports from the Global Telecommunications System (GTS), as well as satellite cloud trail wind data. These reports include air pressure, geopotential height, air temperature, dew point temperature, wind direction and wind speed. The latitude and longitude of the simulation area range from 72.3 °E to 103.2°E and 25.9°N to 40.3°N. This dataset began at 00:00 (UTC) January 1 2010 and ended at 23:00 (UTC) December 31, 2020, which includes 2-m temperature (K), land surface temperature (K), relative humidity (%), surface pressure (Pa), 2-m water vapor mixing ratio (kg/kg), 10-m U and V wind components (m/s), 10m wind speed (m/s), and wind direction (°), precipitation (mm), and dew point temperature (℃).For long simulations, the model provides an alternative to read-in the time-varying data and to update these fields. In order to use this option, one must have access to time-varying Sea Surface Temperature (SST) and sea ice fields. Twelve monthly values of vegetation fraction and albedo are available from the geogrid program. As this data is generated by WRF mode using the warm start method, the precipitation value at time 00:00, 06:00, 12:00, and 18:00 is 0. So the precipitation value is the accumulated precipitation value every 6 hours.
