This is a parameter set for the stochastic weather generator, CLIGEN, for Mainland China. The dataset is modified from the original Creative Commons dataset described in the Wang et al. (2021) publication, CLIGEN Parameter Regionalization for Mainland China. The gridded dataset has a 10 km spatial resolution and consists of 96,676 individual parameter sets. Modifications include addition of two missing parameter types, dew point temperature and wind, that were not part of the original dataset and were later added for completeness. Dew point temperature was taken from the coarser ERA5 dataset at 0.25 arc degree resolution, resulting in repeat values in neighboring grid points in the 10 km grid. Surrogate wind parameters were found using the "International Conversions Program", which is a CLIGEN tool that assists in finding appropriate values for missing parameters. In this approach, wind parameters are taken from ground stations in the 2015 US CLIGEN network that were found to have similar parameter values to those of the original grid. The surrogate wind stations are indicated at the bottom of each parameter file. The file labeling convention was also modified to embed the latitude and longitude coordinates of each grid point into the file name. The grid numbers associated with the original file labels are shown at the top of each parameter file.
