The data are made available as part of the paper "Sensitivity of precipitation in the highlands and lowlands of Peru to physics parameterization options in WRFV3.8.1", submitted to Geoscientific Model Development. This data set incorporates selected postprocessed files needed to reproduce the results presented in the paper. The files are named following the same structure: RR-D02-Kenya-EXPERIMENTNAME-25km3Doms-2008_monthly.nc These are the options available in each case: - EXPERIMENTNAME: Europe, SouthAmerica, Kenya, Micro13 or NoCumulus. These are the names included in Table 1 from the paper. A .txt file including the information about the 175 stations considered for the validation of the WRF experiments is also included. The data is separated with white spaces. The structure of the columns is the following one: STATION LATITUDE LONGITUDE ELEVATION COUNTRY PROVIDER REGION Finally, two .zip files are provided. Scripts.zip includes all the scripts used to read, process and plot the data from the model, and Namelist_files.zip includes all the namelist files used to run the WRF simulations.
