Sea Surface Temperature Team

Sea Surface Temperature Team

The Sea Surface Temperature Team is responsible for the development, science maintenance and validation of various Level 2, 3 and 4 SST products from current and future polar and geostationary satellites. We work with our partners in the NOAA Office of Satellite Products and Operations (OSPO), to generate high- quality SST products and satisfy needs of NOAA and external users, in the areas of climate monitoring, seasonal forecasting, operational weather and ocean forecasting, military and defense operations, validating of ocean and atmospheric models, ecosystem assessment, tourism, and fisheries. We also participate in the international Group for High Resolution SST.

NOAA Enterprise SST System comprises 2 sub-systems:
Retrieval and Monitoring


ACSPO (Advanced Clear-Sky Processor for Ocean)


SQUAM - SST Quality Monitor
  • Monitors global L2 & L3 SSTs w.r.t. L4 fields & in situ data
  • Intercompares and validates various global L4 SST products

Global SST Monitoring & Validation against in situ SSTs (iQuam)
Purpose: QC of in situ SSTs; Online monitoring; Distribution to users

Match-Up Code
Purpose Generate satellite/iQuam match-ups for analysis in SQUAM
ARMS - ACSPO Regional Monitor for SST
Purpose Local monitoring of ACSPO SSTs, for self- and cross-platform consistency
Reference: (Ding et al., in prep)
MICROS - Monitoring IR Clear-sky Radiances over Oceans for SST
Purpose Global monitoring clear ocean BTs vs. CRTM, to ensure high-quality brightness temperatures

3S - Sensor Stability for SST
Purpose Monitoring of AVHRR L1b data, to ensure high quality CAL for accurate brightness temperatures
