Global gridded physical profile data from the U.S. Navy's Generalized Digital Environmental Model (GDEM) product database (NODC Accession 9600094)
The Generalized Digital Environmental Model (GDEM) is a four-dimensional (4-D) steady-state digital model of ocean temperature and salinity. The model consists of gridded sets of coefficients with a grid spacing of 30 arcminutes (') in space and 3, 6, or 12 months in time with the exception of...

The Generalized Digital Environmental Model (GDEM) is a four-dimensional (4-D) steady-state digital model of ocean temperature and salinity. The model consists of gridded sets of coefficients with a grid spacing of 30 arcminutes (') in space and 3, 6, or 12 months in time with the exception of the coefficient describing sea-surface temperature, which is gridded at a 1-month interval. Utilizing these coefficient sets with the appropriate one-dimensional linear or cubic spline interpolation in time, vertical profiles of historical temperature and salinity extending from the surface to the bottom may be computed for a desired time for all locations where the water depth is at least 100 m. The VGDEM is a 4-D model of ocean temperature variability. A number of accumulations and parameters exists for each grid cell such that statistics on the observations can be derived; statistics based on comparing the observations with GDEM can be computed; and statistics computed for the mixed-layer depth and the in-layer and below-layer gradients. The percent of the observations suggesting half-channel is also available. Variability models will be constructed only in the ocean basins where data density permits.
