Ocean Analyses

Some of the ocean analysis produced under ENACT have been made publicly available through a DODS/OPeNDAP server (see highlighted entries on the table below, where a complete list of ocean analyses produced under ENACT is shown). These analyses have been produced using the same agreed-upon settings and have been subsequently interpolated onto a common regular grid (click here for further details on the common settings, analyses features and the common grid). You are welcome to request the analyses in the original grid by directly emailing the group responsible for the analysis you are interested in (click on the partner's name on the table below).

Examples of how to plot/save data residing in a DODS/OPeNDAP server via Ferret.

Please note that more recent ocean reanalyses are available as part of the EU project ENSEMBLES.

DISCLAIMERS

1. The ECMWF analysis under ENACT has never been used for operational purposes. The current ECMWF operational ocean reanalyses (ORA-S3) can be found under the ENSEMBLES data server.
2. Due to a bug discovered in the interpolation software, the INGV subsurface velocity fields are not correctly interpolated on the ENACT common grid. A corrected release of the interpolated velocity fields can be retrieved from their DODs server http://dods.bo.ingv.it/runZ_index.sub. For further informations, please email to dipietro@bo.ingv.it.

Table 1: Summary of ocean analyses produced in ENACT. S1 indicates stream1 (1987-2001); S2 is stream 2 (1962-2001); Sa is the satellite stream (1993-2001). T denotes assimilation of in situ temperature data, S salinity, A altimeter (sea level). OI denotes use of a type of optimal interpolation assimilation scheme, EnKF denotes ensemble Kalman filter scheme. Note: some analyses extend to the end of 2003.

Access to the non-aggregated OPeNDAP server, as well as to the aggregated one is via this link: http://data.ecmwf.int/thredds/

Individual NetCDF files can be downloaded via this link: http://data.ecmwf.int/enact/ . Code convention is:

129: seawater potential temperature
130: seawater salinity
131: zonal current
132: meridional current
133: vertical current
145: sea level

The complete nomenclature conventions are available here.

Using Ferret to plot data and to save fields in Netcdf files

After having installed Ferret (an interactive visualization and analysis software, freely available at http://ferret.wrc.noaa.gov/Ferret/), launch "ferret" from your command line.
