Model Description

The model is configured for the global ocean. Computations are carried out on a mercator grid between 78°S and 47°N (1/12° equatorial resolution). A bipolar patch is used for regions north of 47°N. The horizontal dimensions of the global grid are 4500 x 3298 grid points resulting in ~7 km spacing on average. There are 32 vertical layers (see blkdat.input). Bathymetry is derived from a quality controled NRL DBDB2 dataset. Surface forcing is from Navy Operational Global Atmospheric Prediction System (NOGAPS) and includes wind stress, wind speed, heat flux (using bulk formula), precipitation. For details on the advection scheme, mixing etc. see blkdat.input.

Data Assimilation

There is no data assimilation in this model run.

Operational Details

The model has been run for the time period 01/2003 to 04/2007 and the data are archived at NAVOCEANO. At present, three years of daily data from this run are available via servers located at the Center For Ocean-Atmospheric Prediction Studies (COAPS), Florida State University (FSU). The HYCOM format archive files are converted to CF 1.0 compliant NetCDF files using standard HYCOM post-processing package. These files contain diagnostic output at standard Levitus depth levels for several variables including: currents, temperature and salinity.
