1981-2020年青藏高原标准大气数据集

基于WRF模式，以ERA5再分析资料为初始和边界场，通过动力降尺度的方法，初步获得了青藏高原高分辨率低层大气典型年数据集（青藏高原标准大气）数据集。该数据集时间范围为1993年1月1日－12月31日，时间分辨率1小时，空间覆盖率，水平：整个青藏高原，垂直：高原地面至对流层顶（约海拔18公里），范围25°N-40°N，70°E-105°E，水平分辨率为0.05°，垂直方向共分40层。数据格式为NetCDF，每一小时数据输出一个文件，文件以日期命名。低层大气结构数据包含温度、相对湿度、水汽混合比、位势高度、经向风、纬向风气象要素；地气交换数据集包含地表接收的向上/向下短波辐射、向上/向下长波辐射、地表感热和潜热通量、2米气温和水汽混合比、10米风等。

Based on the WRF (Weather Research and Forecasting) model, using ERA5 reanalysis data as initial and boundary conditions, a high-resolution typical-year dataset of the lower atmosphere over the Tibetan Plateau (dubbed the Tibetan Plateau Standard Atmosphere) was preliminarily constructed via dynamical downscaling. The temporal coverage of this dataset spans from January 1 to December 31, 1993, with a temporal resolution of 1 hour. Spatially, it covers the entire Tibetan Plateau horizontally, and vertically extends from the plateau surface to the tropopause (approximately 18 km above sea level), within the geographic bounds of 25°N–40°N and 70°E–105°E. The horizontal resolution is 0.05°, and a total of 40 vertical layers are included. All data are stored in NetCDF format, with one file output per hour, and each file is named after its corresponding date. The lower atmospheric structure dataset includes meteorological variables such as temperature, relative humidity, water vapor mixing ratio, geopotential height, meridional wind, and zonal wind. The land-atmosphere exchange dataset contains upward/downward shortwave radiation received by the surface, upward/downward longwave radiation, surface sensible and latent heat fluxes, 2-meter air temperature and water vapor mixing ratio, and 10-meter wind.
