U. , S. , and L. Generally, the baseline GSWP-2 forcing overestimates the snowfall (S r ) and rainfall (R r ) rates compared to the Rhône-AGG data. The temporal correlations between both products are relatively poor at the daily and 3-hourly timescale. The overestimation is more pronounced during the cold season (Fig. A.3). It is due to wind corrections since the GSWP-2 wind is also overestimated in winter. Furthermore, GPCC gauge density is dense The P3 precipitation confirms this and reveals a better agreement with the Rhône-AGG data set
