其他变量3个：经度、纬度和行星边界层高度。

A near-surface atmospheric forcing and land surface state dataset over the Tibetan Plateau was developed using the Weather Research and Forecasting (WRF) model. The dataset has a temporal coverage of 2000–2010, spans the geographic region of 25–40°N, 75–105°E, features an hourly temporal resolution and 10 km spatial resolution, with a total grid count of 150 × 300.

In total, this dataset contains 33 variables, which are divided into three categories:
1. 11 near-surface atmospheric variables: 2-meter air temperature above the ground, 2-meter specific humidity above the ground, surface air pressure, zonal component of 10-meter wind field, meridional component of 10-meter wind field, fraction of solid precipitation, accumulated convective precipitation, accumulated grid-scale precipitation, downward shortwave radiation flux at the surface, downward longwave radiation flux at the surface, and accumulated potential evaporation.
2. 19 land surface state variables: soil temperatures at multiple depths, soil moisture contents at multiple depths, liquid water contents in soils at multiple depths, heat flux associated with snow phase change, bottom soil temperature, surface runoff, subsurface runoff, vegetation fraction, ground heat flux, snow water equivalent, actual snow depth, snow density, canopy water, surface skin temperature, albedo, background albedo, soil temperature at the lower boundary, upward heat flux (sensible heat flux) at the surface, and upward water flux (sensible heat flux) at the surface.
3. 3 auxiliary variables: longitude, latitude, and planetary boundary layer height.
