Data formats and file name conventions

At present the OSI SAF HL products are available in NetCDF3, HDF5 and GRIB formats. The HDF5 files have a compression within the format and are therefor considerable smaller than the GRIB files. More details about these formats can be found in the Product Manuals available for each product under Documentation.

At the OSI SAF High Latitude FTP-server all products are stored for one month under the directory prod. In addition, a product archive is also available on the FTP-server, under the directory archive. The products are also available through the EUMETCast service, but only in GRIB format (NetCDF3 for ice drift).

File name conventions at FTP server

Underneath is listed the file name conventions for each of the products used at the OSI SAF High Latitude FTP server.
These abbreviations are used:
{date8}
date on format YYYYMMDD, e.g. 20050328
{date12}
date on format YYYYMMDDHOMI, e.g. 200503281200
{area}
area covered, nh or sh (northern or southern hemisphere)
{ftype}
file type, that is "hdf", "grb" or "nc"
Qual
quality index field
Time
time index field (only SST)
