This data set contains the raw simulation data for an evaluation of a WRF model physics ensemble over the Arabian Peninsula. The data set contains five different experiments (CONTROL, AERO, AERO_YSU, N_AERO_YSU, WDM6) with varying planetary boundary layer (PBL) parametrizations and cloud microphysics. All simulations are performed on a convection permitting horizontal resolution using the WRF-NOAHMP model version 3.8.1 for a single day case study. Additionally, the CF-Conformal NetCDF files used for evaluating diurnal cycles of surface variables are also provided.
