NAME

Gribfiles - Serve grib files on the coast from Oslo and Western Norway

DESCRIPTION

This module make some of our grib files available for access and download. The content is made to support yachts and yachting. Note that these files are meant for downloading and used with external software. All areas have all kind of contents. The data are delivered with content type application/octet-stream

If you need other parameters or areas, please look at THREDDS (NetCDF only, no GRIB).

Data content

The area covered is from 57°54'00"N, 4°26'59"E to 63°00'00"N, 7°00'00"E, in 0.05° increments.

The following variables are included:

Current

• Current (-3 m below sea surface)

Weather

• Pressure (surface)
• Wind (10 m above surface)
• Total precipitation (surface)

Waves

• Significant wave height (surface)

Wave direction

Previously the waves data files followed oceanographic convention, meaning that the value indicated which way the waves were moving. The new model, effective 10 Oct 2023, follows meteorological convention, i.e. where they are coming from.
