SPoRT Sea Surface Temperature (SST) Comparison
Availability Notes:
- These products are available for both the daytime and nighttime passes of each satellite.
- Data loops over the past 21 days.
SPoRT SST v3
Our SPoRT-generated MODIS composites show how clouds can be eliminated with multi-temporal SST imagery while
still preserving data integrity and detailed horizontal gradients. The latency imagery provides insight into the
age of the data making up the composites.
SPoRT SST v6.3
The SPoRT and JPL enhanced SST composite incorporates data from MODIS, AMSR-E, and OSTIA. This allows for
higher resolution and temporal availability. Each 1km pixel is based on the previous seven days of SST data,
weighted based on quality and latency.
NESDIS GOES/POES Daily SST
RTG SST
The Real-time Global Sea Surface Temperature (SST) product
is a 0.5°x0.5° field derived from satellite SST day and night
'superobs', buoy, and ship SST data and is used in the Meso-Eta model at NCEP.
OSTIA SST
The Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) product
is a daily 1/20 degree field derived from satellite data, including MODIS,
provided by the GHRSST project
together with in-situ observations.
Bathymetry Data
These ocean depth images were created from a
set of 2-minute
gridded ocean bathymetry derived from satellite altimetry
observations. These observations were combined with quality-assured shipboard echo-sounding
measurements by Dr. Walter H.F. Smith, of the NOAA Laboratory for Satellite
Altimetry, and Dr. David T. Sandwell, of the Institute of Geophysics and
Planetary Physics at the University of California, San Diego.
