OCEANWEATHER PRES FILE

Oceanweather Pressure File Format

The file format for the Oceanweather pressure file (*.pre) is best described with an example:

The last two arguments of the header is are the starting and end times in yyyymmddhh. The atmospheric pressure data (in units of mbar) is preceded by a header line with the grid information. iLat and iLong are latitude North and longitude West. DX and DY are the grid spacing in units of degrees. SWLat and SWLon are the coordinates of the south-west grid point. DT is the actual time in yyyymmddhhMM.
