ECMWF ERA-15: Sample Data
Abstract
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

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 extracted from European Centre for Medium-Range Weather Forecasts (ECMWF) MARS system and transferred to BADC where they were ingested into the archive. |
| Data Quality: |
See http://www.ecmwf.int/products/data/technical/deficiencies/era15.html for details of known issues with the ERA-15 dataset. Note: for file giua81111712 the GRIB messages (i.e. q at level 22) was corrupted and so that message was replaced with one from the day before to enable users' scripts to run utilising the contents of the directory
|
| File Format: |
Data are GRIB 1 formatted.
