Surface atmospheric pressure derived products

Source data are U.S. Navy Fleet Numerical Meteorology and Oceanography Center (FNMOC) synoptic surface pressure analyses. Primary products are presently derived from the FNMOC 360x181 global spherical one degree surface (mean sea level) atmospheric pressure field nominally available at six-hourly intervals. Historical segments of products were derived from FNMOC 63x63 northern hemisphere polar stereographic or from the FNMOC 73x144 global spherical pressure fields with same nominal availability.

Surface Marine Deck/ship report products

Source data are the unclassified FNMOC surface ship reports archive. This set includes at least some buoy reports, including drifting buoys linked via satellite communication to the global telecommunications system.

Comprehensive Ocean-Atmosphere Data Set (COADS)

Raw (original) reports of global COADS file on CD-ROM for selected regions and software to access the data. These data have limited availability. Presently working on update of COADS release 1a.
