The atmospheric forcing data in the Heihe River basin (2000-2015)


The WRF model was used to prepare the near-surface atmospheric driving data of 2m air temperature, surface pressure, 2m water vapor mixing ratio, radiation, 10m wind field and cumulative precipitation at 0.05 degrees per hour from 2000 to 2015 in heihe river basin.The coordinate system is the longitude and latitude projection.Data is stored month by month, UTC time system, data format is netcdf, naming method: wrfout_heihe_yyyy_mm_01, where "wrfout_heihe_" is a fixed format, representing the result of the second layer of nesting, yyyy is the year, mm is the month, "01" represents every month from the 1st.

Through daily and hourly verification with the observation data of 15 CMA sites and 7 WATER sites, the following conclusions are drawn: 2m surface temperature, surface pressure and relative humidity are relatively reliable, especially 2m surface temperature and surface pressure, the mean error is small and the correlation coefficient is above 0.96;The correlation between the downward short-wave radiation and the observed data at the WATER station was more than 0.9, and the correlation between the downward long-wave radiation was also 0.6.The wind speed of 10m differs greatly from the observed data, and the correlation is weak.The above verification results are for reference only, for specific reference, reference 1 and reference 2.

The data of 2014-2015 were updated in April 2016.

Data for 2016-2018 were updated in October 2019.


Data file naming and use method

File name: data is stored in a grid netcdf format, named: wrfout_heihe_yyyy_mm_01, where "wrfout_heihe_" is a fixed format, representing the result of the second layer of nesting, yyyy is the year, mm is the month, "01" represents each month starting from the 1st.
Data reading: Arcgis or code program can be used to open reading, display as a graphics file.
