The European Centre for Medium-Range Weather Forecasts (ECMWF) has provided global atmospheric analyses from its archive for many years. The ERA-15 Re-analysis project was devised in response to wishes expressed by many users for a data set generated by a modern, consistent, and invariant data assimilation system. The ERA-15 project produced a long time-series (January 1979 - February 1994) of consistent meteorological analyses using a single version of the ECMWF model.

This dataset is a direct copy of disk 1 of the ECMWF Re-Anlysis Sample Data CD-ROM. It contain some evaporation data which is not elsewhere in the CEDA archive. The data are 2.5 degree gridded at 12Z daily for the Re-Analysis period, 1979-1993. The parameters are:

U10 - The 10 meter U wind component (also in BADC archive)

V10 - The 10 meter U wind component (also in BADC archive)

e - evaporation

tp - Total precipitation (large scale plus convective) (also in BADC archive)

tcc - Total Cloud cover (also in BADC archive)

t2 - 2 meter temperature (also in BADC archive)

d2 - 2 meter dew point temperature
