The atmospheric forcing data in the Heihe River Basin (2000-2018)

The atmospheric forcing data in the Heihe River Basin (2000-2018)


Near surface atmospheric forcing data were produced by using Wether Research and Forecasting (WRF) model over the Heihe River Basin at hourly 0.05 * 0.05 DEG resolution, including the following variables: 2m temperature, surface pressure, water vapor mixing ratio, downward shortwave & upward longwave radiation, 10m wind field and the accumulated precipitation. The forcing data were validated by observational data collected by 15 daily Chinese Meteorological Bureau conventional automatic weather station (CMA), a few of Heihe River eco-hydrological process comprehensive remote sensing observation (WATER and HiWATER) site hourly observations were verified in different time scales, draws the following conclusion: 2m surface temperature, surface pressure and 2m relative humidity are more reliable, especially 2m surface temperature and surface pressure, the average errors are very small and the correlation coefficients are above 0.96; correlation between downward shortwave radiation and WATER site observation data is more than 0.9; The precipitation agreed well with observational data by being verified based on rain and snow precipitation two phases at yearly, monthly, daily time scales . the correlation coefficient between rainfall and the observation data at monthly and yearly time scales were up to 0.94 and 0.84; the correlation between snowfall and observation data at monthly scale reached 0.78, the spatial distribution of snowfall agreed well with the snow fractional coverage rate of MODIS remote sensing product. Verification of liquid and solid precipitation shows that WRF model can be used for downscaling analysis in complex and arid terrain of Heihe River Basin, and the simulated data can meet the requirements of watershed scale hydrological modeling and water resources balance.

The data for 2000-2012 was provided in 2013.

The data for 2013-2015 was updated in 2016.

The data for 2016-2018 was updated in 2019.


File naming and required software

Each file contains hourly simulation for a whole month, with UTC time system in netcdf data format. Each file is named as: wrfout_heihe_yyyy_mm_01, where "wrfout_heihe_" is a fixed format, representing the result of nesting in the second layer for Heihe region, yyyy is the year, mm is the month, and "01" is the representative of every month starting from 1st day.
