NOAA Laboratory for Satellite Altimetry

Overview: Near-real time global sea level deviations, relative to the 3-year mean (1993-95), from TOPEX/Poseidon and from ERS-2 altimetry. The TOPEX 10-day files are updated daily at which time the most recent data are 2 days old. The NOAA TOPEX analysis retains all scales of sea level variability, hence the products are useful for large scale work or other analyses which require the complete signal.

Uses: Visualization of ocean currents, seasons, research, input to numerical ocean models, education.
