The microwave radiometer TROWARA measures integrated water vapour ( IWV ) and integrated cloud liquid water ( ILW ) at Bern since 1994 with a time resolution of 7 s. In this study, we compare TROWARA measurements with a simulation of summer 2012 in Switzerland performed with the Weather Research and Forecasting ( WRF ) model. It is found that the WRF model agrees very well with TROWARA 's IWV variations with a mean bias of only 0.7 mm. The ILW distribution of the WRF model, although similar in shape to TROWARA 's distribution, overestimates the fraction of clear sky periods (83% compared to 60%).
