Sea Surface Temperature (SST) Product Details
EVALUATION PRODUCT DETAILS
SPoRT Sea Surface Temperature Composite
The SPoRT SST Composite is blend of VIIRS, MODIS, NESDIS1, and OSTIA SST products (except over the inland lakes, where the NESDIS is unavailable). The algorithm uses a 7-day collection of VIIRS MODIS (Aqua and Terra) level-2B data and the most recent NESDIS and UKMO2 daily products. Two type of weighting are used in the compositing process. One weight is for the data latency and the other for the product type. The VIIRS and MODIS data, being at 750m and 1km resolution respectively, are given the most weight. All available confidence flags and bias information are incorporated. The final composite is calculated on the north hemisphere 2-km grid (to 80N). The SPoRT SST Composite product is computed twice-daily (0000-1159 UTC and 1200-2359 UTC). The VIIRS, MODIS and OSTIA data are obtained in near-real time from the GHRSST archive at JPL.
1 The National Environmental Satellite, Data, and Information Service (NESDIS) GOES/POES SST Composite uses satellite data from GOES and POES. This product has global coverage at approximately 5-km resolution and is generated once per day. Additional information can be found at the NESDIS site.
2 The United Kingdom Met Office (UKMO) Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) system. This product has global coverage at approximately 6-km resolution and is produced once per day. Additional information can be found here.
