The RMSEs in this figure are calculated by choosing HRRR.A as benchmark. By selecting strip areas with distances of 0-30 km and 60–90 km from the inner region boundary, the performance of YingLong-HRRR.F24 with boundary smoothing (blue lines) and coarse (i.e. direct replacement, green lines) are compared.
