Gridded Sea Level Anomaly and Dynamic Topography Database from TOPEX/POSEIDON Altimetry Data at the Univ. of Texas, AustinEntry ID: UTEXAS_AUSTIN_CSR_TOPEX_SSH
Abstract: This data base contains gridded sea level anomaly heights observed by
the TOPEX/POSEIDON (T/P) satellite altimeter. The sea level anomaly
is the deviation of the sea surface away from a mean surface.
The dynamic ocean topography heights are determined by applying all
media and instrument corrections (ionosphere, wet and dry troposphere,
and electromagnetic ... bias) and geophysical corrections (tides and
inverted barometer) to the measurements. The altimeter measurements
are reduced to sea surface topography heights using a precise orbit
computed at Univ. of Texas Center for Space Research using the
available Satellite Laser Ranging and DORIS doppler tracking data.
Gridded sea surface height anomalies are available for each repeat
cycle of the satellite, and as 3-year and 5-year average grids.
GIF files containing color maps of the global sea level anomalies for
each repeat cycle are available.
