GEOSAT Altimeter Crossover Differences from the Geodetic Mission, on CD-ROMEntry ID: GEOSAT_XOVER_DIF
Abstract: The first 18 months of Geosat operations (April 1985 to September 1986)
were referred to as the Geodetic Mission. Data from the Geosat Geodetic
Mission were collected for military use, but were declassified in 1996.
The altimeter crossover differences from the Geodetic Mission are
unclassified and are contained on this set of eight CD-ROMs in the form
of crossover difference records (XDRs).
... Although only the 18-month Geodetic Mission data were classified, XDRs
were constructed for the first 2.5 years of the Geosat mission, that is,
data from the Geodetic Mission plus the first year of the Exact Repeat
Mission. This was done to minimize the effect of the 5-week data gap
(October 1 to November 8, 1986) between the two missions. The GEOSAT
Altimeter Crossover Difference data are organized by geographic region.
The data are in a binary Hewlett-Packard format, but each disc contains
a module that enables the data to be converted to binary VAX format. The
Geosat altimeter crossover difference records are documented in a NOAA
handbook, a copy of which is provided with each order.
NOTE: Advanced programming skills are strongly recommended for users of
this CD-ROM product.
