NOAA Advanced Clear-Sky Processor for Ocean (ACSPO): sea surface temperature, clear sky radiances, and aerosol optical depth for the global ocean, 2011 - present (NCEI Accession 0072979)
Advanced Clear Sky Processor for Ocean (ACSPO) is the NOAA Enterprise Sea Surface Temperature (SST) system. It is currently used to produce a consistent line of SST products from several VIIRS, AVHRR FRAC and GAC, MODIS, ABI, and AHI sensors, flown onboard polar (SNPP/NOAA-20, Metop-A/B, NOAA-16 to 19, Terra/Aqua) and geostationary (GOES-16, Himawari-8) satellites. Two products are produced from each platform/sensors, in a community-consensus Group for High-Resolution Sea Surface Temperature (GHRSST) Data Specification version 2 (GDS2) NetCDF format: L2P (in original swath projection) and L3U (gridded uncollated 0.02deg resolution). Two-week rotated buffers of each ACSPO product are available in Near-Real Time (NRT) via the NOAA Coast Watch site, along with two reprocessed (Reanalyses, or RAN1) products: from SNPP VIIRS (Mar 2012 - 15 Dec 2015) and from AVHRR GAC onboard multiple NOAA and Metop satellites (Aug 2002 - present).

Supplemental Information | SST is used in many applications including monitoring of climate variability, operational weather and seasonal forecasting, military and defense operations, validation and/or forcing of the ocean and atmospheric models, ecosystem assessment, tourism, and fisheries. Satellite SST retrievals are assimilated into climate, mesoscale atmospheric, and sea surface numerical models, which form the cornerstone of the operational ocean forecasting systems. The quality and accuracy of ACSPO products is monitored in near-real time by the following systems: SST Quality Monitor (SQUAM), In situ SST Quality Monitor (iQuam), ACSPO Regional Monitor for SST (ARMS), and Monitoring of IR Clear-sky Radiances over Ocean for SST (MICROS 2). |
Purpose | The purpose of the AVHRR Clear-Sky Processor over Oceans is to produce clear-sky products over oceans from the Advanced Very High Resolution Radiometer (AVHRR) for the designated user community. |
