NOAA AVHRR Clear-Sky Products over Oceans (ACSPO): Sea Surface Temperature, Clear Sky Radiances, and Aerosol Optical Depth for the Global Ocean, 2011 - present

Metadata Updated: August 11, 2023

Advanced Clear Sky Processor over Oceans (ACSPO) - generates Sea Surface Temperature product files from multiple platforms and sensors. The products are from the AVHRR instrument aboard the older POES series of spacecrafts, as well as from the European Metop mission. Beginning on October 14, 2017, the ASCPO data changed formats from HDF4 to NetCDF4 to adhere to the Group for High Resolution SST (GHRSST) GDS2 data specification. Two spatial resolutions had been provided, 4 km from GAC data and 1 km from the Metop FRAC data.

Other parameters that can be found in the product files can include (dependent on date and product type) satellite and solar geometry (solar and satellite zenith angles and relative azimuth angles), thermal band brightness temperatures, visible band albedos, and bit flags indicating viewing conditions such as cloud, day/night, sun glint, etc. Also included in the current GHRSST files are an SST quality indicator, delta SST compared to a reference SST from a current SST analysis from an independent source, numerical weather model forecast u and v wind, as well as single sensor error statistics (SSES) (bias and standard deviation) at each pixel.
