This dataset contains: a) Reanalysis ensemble simulation output for 1980-2010. Produced with NorESM-ME and atmospheric nudging. b) Seasonal hindcasts, started from the reanalysis, started on Jan, Apr, Jul, Oct, every year over the period 1985 – 2010. c) Decadal hindcasts, started from the reanalysis, each October, every other year, for the years 1985-2010.

The dataset consists of three folders: - NudA-UV: NorESM + atmospheric anomaly nudging of horizontal winds - NudA-UVT: NorESM + atmospheric anomaly nudging of horizontal winds and temperature - NudF-UVT: NorESM + atmospheric full-field nudging of horizontal winds and temperature

Each folder includes the a) reanalysis and b) seasonal and c) decadal predictions.
