In this repository, we include the source codes used in the WAF publication "Effects of ice-crystal-related parameters in cloud microphysics parameterization to simulated winter precipitation over the Korean Peninsula" There are WDM6 codes and parameter sets in "Model_codes" for WRF simulation and "Figures" has a scripts for the figure of the manuscript. In "Model_codes", the text file starting with LHS is 50 parameters sets generated by the Latin hypercube sampling method, and the text files starting with the case are the set of parameters used for the SEN experiment for each case. There are two WDM6 codes, the CTL code uses the parameter set in Table 1 as CTL, and the LHS code uses the 50 parameters set in the text file. In "Figures", there is a script corresponding to each figure of the paper.
