Abstract:
Sea Surface Temperature (SST) is an important characteristic of the global ocean. It has been routinely monitored at NOAA since the early 1980s using AVHRR onboard polar NOAA and Metop satellites and imager onboard GOES satellites since mid-1990s.

In October 2011, the S-NPP satellite, first in the new US Joint Polar Satellite System (JPSS) series, was launched, to be followed by J1 and J2 in 2017 and 2021. The Visible Infrared Imager Radiometer Suite (VIIRS) instrument onboard JPSS has superior resolution, radiometric stability, and imagery. NOAA operationally generates a VIIRS SST product with unprecedented accuracy and global coverage, using its Advanced Clear-Sky Processor for Oceans (ACSPO) system. VIIRS SSTs are used in weather and climate applications at NOAA and nation- and worldwide.

In 2016, NOAA plans to launch GOES-R, the first of a new geostationary satellite series. It will carry a superior Advanced Baseline Imager (ABI) onboard. The Japanese Himawari-8 (H8) satellite launched in October 2014 carries an Advanced Himawari Imager (AHI), a very close proxy of ABI. NOAA has developed an experimental SST product from H8 AHI and is testing out an end-to-end processing chain with H8 SST to get ready for GOES-R launch.

The presentation discusses the ACSPO SST products and their monitoring in the NOAA SST Quality Monitor (SQUAM; www.star.nesdis.noaa.gov/sod/sst/squam/). ACSPO SSTs are also routinely validated against quality controlled in situ data produced by another NOAA system, in situ Quality Monitor (iQuam; www.star.nesdis.noaa.gov/sod/sst/iquam/). Clear sky ocean radiances used for SST retrievals are monitored for stability and consistency with similar products from other polar and geostationary sensors in the NOAA Monitoring of IR Clear-sky Radiances over Oceans for SST (MICROS; www.star.nesdis.noaa.gov/sod/sst/micros/). This presentation discusses performance of ACSPO SST products, their applications and data access.
