European Centre for Medium-Range Weather Forecasts Operational Analysis data set

Operational analyses from the European Centre for Medium-Range Weather
Centre (ECMWF) are available through BADC for the period since March
1994. The data is updated monthly, two to three weeks after the end of
the month, e.g data for June becomes available soon after mid
July. Vorticity, divergence, temperature, surface pressure and
vertical velocity data in T106 spectral form plus specific humidity on
a gaussian N80 grid are available on the original model levels and
also interpolated to standard pressure levels. Surface data such as
temperature, soil wetness, snow depth etc are also available on the
gaussian grid.

Although the ECMWF model is run at T213 (N160) resolution for this
period the data available through the BADC are at T106 (N80)
resolution for consistency with the ECMWF Reanalysis project (ERA)
data and in order to reduce storage requirements. This dataset
therefore complements and updates the ERA dataset, which is also
available through the BADC.

Data on a lat-long grid is also available, see ECMWF gridded dataset
