DMSP Total Ozone, Calibrated Radiance and Total Ozone Grid Point Data Archived at NSSDC

Both the ozone and calibrated radiance data were placed in a computer data base called Satellite Ozone Analysis Center (SOAC). The data base was constructed on a VAX 11/780 computer with a VMS operating system using the FRAMIS code, a relational data base manager. The data base contains the MFR total ozone calibrated radiance data from all four DMSP block 5D-1 satellites.

Each block contains 20 records; each record contains 469 characters. An ozone grid point value is expressed to the nearest tenth of a m-atm-cm. Each file on a tape represents the gridded data for 1 calendar day beginning at 0000Z Greenwich Mean Time (GMT).

A file may contain as many as four grids, one for each of the DMSP block 5D-1 satellites. The grid in each hemisphere is a 67 x 67 rectangular matrix of points superposed on a polar stereographic map base.
