Geosat Chapter 2 Geosat JGM-3 GDRs 2. The remaining eight disks contain only GDR data files. These tables are useful for describing the collinear aspects of the two mission phases.
All subsequent passes follow in time order.
The ascending passes are therefore all odd numbered and the descending passes are even. In all four plots, the symbols are color-coded by cycle number. During the GM the slow drift of the orbit causes a rainbow effect as the equator crossing longitude moves westward for subsequent cycles. Program ligdr.f is used to make text listings of the contents of the binary GDR files.
