Statistical Downscaling of ERA-Interim Forecast Precipitation Data in Complex Terrain Using LASSO Algorithm
Figure 2
Annual precipitation bias (bars) between ERA-Interim and MeteoSwiss stations in percent for the period 1983–2010. Positive values indicate an overestimation of the annual precipitation by ERA-Interim and vice versa. The line with dots indicates altitude differences, , defined as ERA-Interim grid height minus site elevation.
