13.1 Data files

The DATABASE contains approximately 160MB of IEEE 32bit data and the files are named as follows:

•  scripps.top is the Scripps topography (265816 bytes).

•  hellerman.tau is the Hellerman/Rosenstein (1983) windstress climatology (1757496 bytes).

•  oorts.air is the Oort (1983) 1000mb air temperature climatology (294268 bytes).

•  levitus.mask is the Levitus (1982) land/sea mask (8680716 bytes).

•  ann.temp is the Levitus (1982) annual mean potential temperatures (8682036 bytes).

•  ann.salt is the Levitus (1982) annual mean salinities (8682036 bytes).

  Then there are the Levitus (1982) monthly climatological potential temperatures. There are twelve monthly files where the three letter suffix gives the month.

•  jan.temp is the Levitus (1982) monthly mean potential temperatures (4998748 bytes).

  The remaining eleven monthly temperature files are of the same size but use a different month as the suffix.

  Then there are the Levitus (1982) monthly climatological salinities. There are twelve monthly files where the three letter suffix gives the month.

•  jan.salt is the Levitus (1982) monthly mean salinities (6314208 bytes).

  The remaining eleven monthly salinity files are of the same size but use a different month as the suffix.

Note that the file size for the monthly Levitus (1982) data is less than the file size for the annual means. This is because seasonal effects only penetrate down to 1000m or so and the monthly data only extends to this depth. Also, salinity has been interpolated from four seasonal values to twelve monthly values within this dataset. All Levitus (1982) data as well as Hellerman/Rosenstein (1983) and Oort (1983) data has been forced into land areas on their native grid resolutions by solving

$$\nabla^2\xi_{i,jrow}=0$$ (13.1)

over land areas using values of $\xi_{i,jrow}$ over ocean areas as boundaries values where $\xi_{i,jrow}$ represents the various types of data. This method is similar to what was done with surface boundary conditions in Section 19.1.2.
