This data set contains the results of two WRF simulations for July and August 2013. The model domain encompasses a latitude-belt between 20° N and 65° N and WRF version 3.7.1 was applied. One simulation was carried out on a horizontal resolution of 12 km while the second simulation has been carried out on a convection permitting resolution of 0.03°. The data set contains surface and pressure level data for both experiments. The corresponding publication of Schwitalla et al. (2017) can be found here: https://doi.org/10.5194/gmd-10-2031-2017
