News on Data Archiving and Dissemination

• Update of the Documents to Encode the s2d Data in NetCDF (22/10/2007)

  The two documents mentioned below have been updated. There are changes in the structure of the metadata and more information about the descriptors required to correctly specify the physical variables. This table summarizes the main features of the CF-compliant naming for the physical variables required.

• First release of the s2d public data server (28/02/2007)

The first version of the public data dissemination system of the s2d data is now available. It provides atmospheric data from the stream 1 in both GRIB and NetCDF formats using MARS-based and OPeNDAP servers.

• Encoding of s2d Ensemble Integrations in NetCDF (20/06/2006)

  Two documents (still under discussion) describe the conventions to encode CF-compliant NetCDF files containing ensemble forecasts. The first document describes the structure of the metadata to be used with special emphasis in the ancillary variables that describe the way the ensemble has been generated. The second document lists the standard names of the variables as required by the CF convention.

• S2d Archiving of Common Variables at ECMWF (18/11/2005)

A set of common atmosphere and ocean variables from the s2d integrations are stored at ECMWF for quality control, basic forecast quality assessment and dissemination.

Atmospheric variables are archived in MARS in GRIB format. The fields are stored following a set of atmospheric conventions, based on DEMETER and the operational European multi-model seasonal forecasts.

The ocean encoding is carried out using rules based on the ENACT conventions, with storage of CF-compliant NetCDF files into ECFS. The ENSEMBLES s2d ocean conventions allow the preparation of the NetCDF files and their archiving.

• Specific Variable Definitions (25/10/2005)

Additional information is required to properly define some of the S2D data. Follow this link to find some model-specific definitions of some variables.

• S2d Common Lists of Variables (23/02/2005)

  A list of atmosphere and ocean variables has been defined for a common archiving of the s2d experiments. The list describes the basic set of variables that are archived at ECMWF in MARS (atmosphere, in GRIB format) and ECFS (ocean, in NetCDF format) by all the s2d models.

  Please, check all this information before producing the files with your model output. The users of these data should bear in mind that additional variables, as described in the RT2A lists compiled by Jean-François Royer, are available under request from individual model partners.
