Description

The data set includes fields from control and nudged experiments by ECMWF model described in Karpechko et al. (2025) together with corresponding ERA5 verification fields. The fields are bi-weekly averaged (weeks 1-2, 3-4, 5-6) sea level pressure, 2-metre temperature and total precipitation, and weekly mean (weeks 1 to 6) NAO and PNA indexes. The python codes can be used to reproduce the results of the paper. Reference: Karpechko, A., Butler, A., and Vitart F.
