NORWCOM (the NORWegian ECOlogical Model system) is a coupled 3D physical, chemical and biological model system for the North Sea (Skogen et al., 1995, Skogen & Soiland 1998). Main development and maintenance is done at the Institute of Marine Research. At this page you can download a 1985-2008 hindcast. The full hindcast (salinity, temperature, currents, water elevation, phytoplankton, nutrients and oxygen) is available as monthly averages at high resolution (0.1 degrees) in netCDF. In addition a selected set of products (sea surface and bottom – salinity and temperature) at low spatial resolution (0.5 longitude x 0.25 latitude) for a limited area (3W, 50N) to (10E, 63N) is available as ASCII files.
For the set-up, validation and more info of the simulation, please refer to Hjøllo et al., 2009; Skogen & Mathisen, 2009.
Low resolution (ASCII via ftp).

Description: The values are monthly mean over rectangular (0.25 latt, 0.5 long) boxes from (3W,50N) to (10E,63N), such that in each file the first point (upper left) is the mean over (3W-2.5W, 63N-62.75N). The next point (same line) mean over (2.75W-2.5W, 63N-62.5N) and so on, ending in the lower right corner of the file (and North Sea) as the mean over (9.5E-10E, 50N-50.25N). In land points the value -9.9 is used. In total the grid contains 26x52 points.
High resolution (netCDF via OpeNDAP).
