Both GEO and LEO satellites can provide sea surface temperature (SST) observations. The GOES series of GEO satellites provides continuous sampling of SSTs over the Atlantic and Pacific Ocean basins. The MODIS instrument on the Aqua satellite has been providing daily, global SST observations continuously since the year 2000. Visible wavelengths are useful for detecting ocean color, particularly from LEO satellites, which are often observed at very high resolutions.

Additionally, LEO satellites can detect global sea‐surface anomaly parameters. Jason‐3 is a low‐Earth satellite developed as a partnership between EUMETSAT, NOAA, NASA, and CNES. The radar altimeter instrument on Jason‐3 is sensitive to height changes less than 4 cm and completes a full Earth scan every 10 days (Vaze et al., 2010).
