NOAA Advanced Clear-Sky Processor for Ocean (ACSPO): sea surface temperature, clear sky radiances, and aerosol optical depth for the global ocean, 2011 - present

Description

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).
