WRF-Chem simulations of CO2, CH4 and CO around Xianghe, China

This data set contains the hourly WRF-Chem v4.1.5 model output over three nested domains centered around the Xianghe site in China (39.75° N, 116.96° E).

The simulation period is from 16 August 2018 until 1 September 2019. The model output files are in NetCDF format and contain a wide range of meteorological variables as well as concentration fields for CO2, CH4 and CO split in different tracers depending on the source sector. A complete list of all the variables is given in the model variables text file. The corresponding namelist.input text file is also provided.

This data set is presented in
