NASA/GSFC Wallops Flight Facility TOPEX Radar Altimeter Support
Overview: The Observational Science Branch (OSB) TOPEX group performs
engineering assessment and monitoring of the TOPEX dual-frequency altimeter
(ALT) data. Daily summaries are formed from the ALT Instrument Files (AIF),
and a summary AIF database is updated with various calibration, engineering,
and waveform parameters. Another summary database is built for the Geophysical
Data Records (GDR). The OSB GDR database contains 1-minute averages of
selected science parameters for deep-water and non-flagged data; this
database is updated weekly using the Intermediate GDRs (I/GDRs). When
JPL releases the GDR tapes the I/GDR data are replaced by the GDR data
in the database.
