The BADC is extracts ECMWF Operational Analysis and Forecast data on a daily basis to keep pace (with a slight delay) with production. By agreement with the ECMWF the BADC does not make Operational data available until 10 days after the forecast has been produced.
Table 1 lists changes that have been made to archive that may be of interest to users.

|30/09/2003||Note that a new method to create U/V wind components from the vorticity and divergence was implemented in the ECMWF MARS server at 11:00 GMT on 30th September 2003.|
|20/09/2002||BADC begins extracting Operational data in the same format as the ERA-40 Re-analysis data for consistency. These data are in Spectral T159 (upper air) and N80 Reduced Gaussian Gridded (surface and some upper air parameters) resolutions. A full listing of the available products and the location of the data are provided on the Operational data parameters page.|
