Spatial distribution of seasonal mean daily precipitation (mm day−1) for the CONUS, Alaska, and Puerto Rico during the 2001–2020 period. The data is sourced from ADDA_V2 (first row), Observation-based gridded dataset (second row), ADDA_V2 minus Observation-based gridded dataset (third row), and ERA5 minus Observation-based gridded dataset (fourth row). PRISM (Daymet) is utilized for CONUS (Alaska and Puerto Rico) as the observation-based gridded dataset. Hatches on the first row indicate grid points with value added by dynamical downscaling. On the third and fourth rows, grid points with statistically significant differences at 95% confidence level are marked with hatches.
