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

Use of these data is covered by the following licence(s): https://artefacts.ceda.ac.uk/licences/specific_licences/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.
