Data DescriptionAVHRR Clear-Sky Products over Oceans (ACSPO) - The Advanced Clear Sky Processor for Ocean (ACSPO) is the NOAA Enterprise SST system. The ACSPO system produces a consistent suite of SST products from multiple platforms and sensors. The products included in this CLASS data family were produced from observations acquired by the Advanced Very High Resolution Radiometer-3 (AVHRR-3) instrument onboard the following polar orbiting satellites: NOAA-18, NOAA-19, MetOp-A, MetOp-B, and MetOp-C. Products are provided in 4 km (GAC) resolution or 1 km (FRAC) resolution. Note, the ACSPO L2P and L3U products are produced in the Group for High-Resolution SST (GHRSST) Data Specification version 2 (GDS2) NetCDF format, whereas the other products are provided in the HDF data format. Additional file parameters (dependent on date and product type) include satellite and solar geometry, 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 GHRSST files are SST quality indicators, numerical weather model forecast wind, and single sensor error statistics (SSES) for each pixel. The data are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) as daily gridded files in the HDF-EOS and netCDF-4 file formats with attributes included.
