Satellite
Oceanography and Climatology Division
Laboratory
for Satellite Altimetry
LSA specializes
in the analysis of satellite altimeter data related to problems in physical
oceanography and marine geophysics.
The following
projects are presently active in our group.
 Sea Level
Rise - Satellite altimeter observations from the RADS database system
are used for determining global and regional mean sea level trends from 1992
to the present, as well as sea level trend maps.
Sea Ice Research Group
- Laser and radar altimeter observations are used to determine
changes in sea ice volume.
Near-Real
Time Analyses - Altimeter data, processed daily within 1-2 days of acquisition,
are used operationally for determining ocean currents,
monitoring sea level, and are assimilated in
models to improve forecasts of El Nino and hurricane intensity.
Topex/Poseidon
Historical Sea Level - Altimeter analyses from the NASA/CNES Topex/Poseidon
altimeter mission (1992-present) are provided in terms of sea level deviations
and anomalies. Data are available along the satellite track, in gridded
form, or as color maps.
ERS
Altimetry - Altimeter data have been collected since 1991 by the
European Space Agency's ERS-1 and ERS-2 satellites. ERS-2 data are processed
daily by LSA within a few hours of collection by the satellite.
Geosat
Follow-On - Launched in 1998, the US Navy GFO altimeter has had
many problems, but has been operating continuously since Dec. 2000. These data
will complement those collected by Geosat
during 1985-89.
Geophysics
Research - Altimetry contributes to determination of gravity anomalies
over the ocean. These fields provide information about plate tectonics
and bottom topography. Areas of specialty include the polar regions
and the southwest Pacific.
Geophysics
Products - Posters, CD-ROMs, and latest images.
Sea
Floor Topography - An interactive global sea floor topography map.
