NORA10

The NORA10 hindcast is produced by running an atmospheric downscaling of the ERA-40 reanalysis and wave hindcast covering the Norwegian Sea, the North Sea, and the Barents Sea (Reistad et al, 2011; Aarnes et al. 2012; Furevik and Haakenstad, 2012). The period covered is from September 1957 to 2022. The dynamic atmospheric downscaling is performed as a series of 9 hours prognostic runs initialized from a blend of ERA-40 and the previous prognostic run.

The nested WAM wave model hindcast consists of a coarse 50 km model covering the North Atlantic forced with ERA-40 winds and a nested 10–11 km resolution model forced with downscaled winds. 

Data are available on request.
