Altimeter Data

Atlantic Ocean Real-Time Maps of Sea-Level Anomalies from NOAA AOML (http://www.aoml.noaa.gov/phod/dataphod/work/trinanes/INTERFACE/index.html) - JASON-1, TOPEX, ERS-2, ENVISAT and GFO Sea Height Anomaly (SHA) and Significant Wave Height data are available here on a near-real time basis with a 2-day average delay.

Global Maps of Sea-Level Anomalies From Combined Altimeter data from Ssalt/Duacs (http://www.jason.oceanobs.com/html/donnees/duacs/welcome_uk.html) - Near real time maps of sea level and anomalies of sea level.

Global Maps of Winds and Waves From Topex/Poseidon Altimeter Data from Ssalt/Duacs (http://www-aviso.cnes.fr:8090/HTML/information/frames/applications/actu/vent_vagues_uk.html) - Near real time maps of sea level and anomalies of sea level.

Real-Time Maps of Sea Level and Temperature from University of Colorado (http://e450.colorado.edu/realtime/welcome/) - This site allows you to create maps of sea-surface height globally, or for the Gulf of Mexico, based on the latest altimeter data. Maps are produced from Jason, TOPEX/POSEIDON(T/P), Geosat Follow-On(GFO) and ERS-2 altimeter data processed in near real-time, usually within 12 to 36 hours of overflight. An analysis product is based on the latest 10 days of Jason and T/P, 17 days of GFO and 35 days of ERS-2 sampling, if available. Data are available back to 1993.

NASA Near-Real-Time Image Distribution Service
(http://nereids.jpl.nasa.gov/cgi-bin/nereids.cgi?show=current) - NEREIDS is a near-real-time image distribution server. This server provides satellite browse images within 24 hours of capture and keeps the data in a short-term rolling store.

Monthly and Annual Maps of Sea-level and Sea Surface Temperature from the NASA Jet Propulsion Laboratory 1992-present
(http://sealevel.jpl.nasa.gov/science/time-series-data.html) - For the past 10 years, oceanographers from all over the world have been riding wave after wave of amazing sea surface height (SSH) data. Orbiting from 1336 kilometers (830 miles) in space, the NASA/CNES TOPEX/Poseidon spacecraft keeps cranking out never before seen views of our Ocean Planet. At the same time, the National Oceanic and Atmospheric Administration's (NOAA) Polar Orbiting Satellites have been measuring the sea surface temperature (SST) of all our oceans. These images and animations complement each other in many, many ways ... for scientists, their sum is much more than each individually.
