ECMWF Gridded Global Analyses 1985-1992

The data are here.

We have gridded global analyses from the European Center for Medium Range Weather Forecasts, Reading, England for the years 1985-1992 inclusive. The analyses are uninitialized, meaning that observed data have been assimilated into the ECMWF forecast model but have not been altered by the model's normal mode initialization scheme. The analyses are monthly averages.

All variables are on 14 pressure levels which are in mb:

10, 30, 50, 70, 100, 150, 200, 250, 300, 400, 500, 700, 850, 1000

The variables currently in the data catalog are:

temperature, zonal and meridional velocity and geopotential.

In addition there are surface fields of surface pressure, surface geopotential and temperature 2m above the surface. All these are gridded on a 2.5 by 2.5 degree grid.

These data sets were derived from the archived ECMWF analyses that, in their entirety, are maintained on tape. Other variables that could be read from the tapes and formatted and cataloged like the data mentioned above are:

relative humidity, land-sea mask, surface temperature, 10m winds and vertical velocity.

If anyone wishes to see these variables they should contact Richard Seager who will arrange for reading them off the ECMWF tapes.
