ECMWF 40 Year Re-analysis (ERA-40) Basic Surface Forecast Data Sets





 

 
  Please use our Online Ordering system to order this data set.

Description:

  • Fields are forecasts with steps 3 and 6 from base times 0000, 0600, 1200 and 1800 UTC each day; forecasts from base times 0000 and 1200 UTC also have steps 9, 12, 15, 18, 21, 24, 30 and 36;
  • Each parameter at each level is stored as a grid point field at 2.5° resolution.

Fields available are:

2 metre dewpoint temperature, 2 metre temperature, 10 metre u and v wind components, boundary layer dissipation, boundary layer height, convective precipitation, convective snowfall, East/West surface stress, evaporation, forecast albedo, forecast log surface roughness for heat, forecast surface roughness, gravity wave dissipation, high cloud cover, ice surface temperature levels 1, 2, 3 and 4, instantaneous moisture flux, instantaneous surface heat flux, instantaneous X surface stress, instantaneous Y surface stress, land-sea mask, large scale precipitation, large scale precipitation fraction, large scale snowfall, latitudinal component of gravity wave stress, low cloud cover, maximum temperature at 2 metre since previous post-processing, mean sea level pressure, medium cloud cover, meridional component of gravity wave stress, minimum temperature at 2 metre since previous post-processing, North/South surface stress, runoff, sea ice cover, sea surface temperature, skin reservoir content, skin temperature, snow albedo, snow evaporation, snow density, snow depth, snowfall, snowmelt, soil temperature levels 1, 2, 3 and 4, sunshine duration, surface geopotential, surface latent heat flux, surface net solar radiation clear sky, surface net thermal radiation clear sky, surface sensible heat flux, surface solar radiation, surface solar radiation downward, surface thermal radiation, surface thermal radiation downward, surface stress/Charnock, temperature of snow layer, top net solar radiation clear sky, top net thermal radiation clear sky, top solar radiation, top thermal radiation, total cloud cover, total column ozone, total column water, total column water vapour, volumetric soil wetness levels 1, 2, 3 and 4, wind gust at 10 metres.
