TOPEX/POSEIDON ALTIMETER MERGED GEOPHYSICAL DATA RECORD GENERATION B

10.5067/TPMGD-BIN0B

PODAAC_MGDR

The TOPEX/POSEIDON MGDR (Merged Geophysical Data Record) contains global coverage altimeter data. This data set (MGDR-B) contains generation B data which replaces the generation A data set. The objective of the TOPEX/POSEIDON mission, launched in August 1992 and currently operating, is to determine ocean topography with a sea surface height measurement precision of 3 cm and a sea level measurement accuracy of 13 cm. The data product combines measurements from two altimeters, a NASA dual frequency (Ku and C band) instrument similar to the Geosat altimeter, and a French (CNES) instrument which is a proof-of-concept solid-state altimeter (Ku band). This data set contains mean sea surface, ionospheric corrections, sigma0 and all parameters needed to calculate sea surface height anomalies and total electron content. The data are in binary format.
