Abstract
This dataset contains 1.5 degree gridded, analysis time step wave model data from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from September 1957 to August 2002. ERA-40 followed on from the ERA-15 re-analysis project. These data are GRIB formatted.

Access rules: |
Access to these data is available to any registered CEDA user. Please Login or Register for an account to gain access.
Use of these data is covered by the following licence: http://licences.ceda.ac.uk/image/data_access_condition/ecmwf-era-products.pdf. When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
Data lineage: |
Data were generated by the ERA-40 project at European Centre for Medium-Range Weather Forecasts (ECMWF) and stored within ECMWF's archives. The BADC then obtained a copy from the ECMWF archived and ingested into the BADC archives to aid wider academic use of these data. |
