ERA-20C is a climate reanalysis dataset covering the period 1900 to 2010.
ERA-20C assimilates observations of surface pressure and surface marine winds only. It is an outcome of the ERA-CLIM project.
The ERA-20C analysed surface parameters that are only available 6-hourly are those that are produced by the land-surface analysis scheme. Separate from the 4D-Var assimilation, the land-surface analysis scheme runs every 6 hours and only produces one temporal estimate at the centre of each 6-hour window. These 6-hourly parameters are:
The other ERA-20C analysed surface parameters are available 3 hourly. All the ERA-20C forecast surface parameters are available 3 hourly (from daily forecasts beginning at 0600UTC).
