Statistical Downscaling of ERA-Interim Forecast Precipitation Data in Complex Terrain Using LASSO Algorithm

Table 3

Comparison of ERA-Interim forecast daily precipitation with observations at 50 meteorological stations from 1983 to 2010. CR, RMSE, and MAE in mm are listed. The elevations of sites are different with ERA-Interim grid heights, so the altitude differences (Δℎ, ERA-Interim grid height minus elevation) are also labeled.
