This archive contains the reanalyses spanning the past few centuries produced with paleo-NorCPM: paleo-NorCPM1 offline reanalysis (from 1501 to 2010) wind-nudged reanalysis (from 1601 to 2000) For each reanalysis, the ensemble mean and variance are provided at monthly resolution for the following variables: PRECT – Total precipitation (m s-1) PSL – Sea-level pressure (Pa) TREFHT – Near-surface (2 m) air temperature (K) U850 – Zonal wind at 850 hPa (m s-1) V850 – Meridional wind at 850 hPa (m s-1) T850 – Atmospheric temperature at 850 hPa (K) Z500 – Geopotential height at 500 hPa (m) fice – Sea-ice concentration (%) SPEI – Standardized Precipitation Evapotranspiration Index (unitless) In addition, for the wind-nudged reanalysis, the following variables are provided: MOC26 – AMOC strength at 26° North (Sv) OHC_global_0000-700m – Global ocean heat content from the first 700 meters (ZJ). mld – Mixed layer depth (m) As for oceanic variables, those have been interpolated on the CAM4 f19 grid (1.9° × 2.5° latitude–longitude). The full ensemble is available following this link: https://ns9039k.web.sigma2.no/datalake/dalaiden/paleo-NorCPM1/all_members. More variables are available.
