NOAA ACSPO v2.70 GOES-16/East ABI L3C SST

The ACSPO G16/ABI L3C (Level 3 Collated) product is a gridded version of the ACSPO G16/ABI L2P product available at https://podaac.jpl.nasa.gov/dataset/ABI_G16-STAR-L2P-v2.70 . The L3C output files are 1hr granules in netCDF4 format, compliant with the GHRSST Data Specification v2 (GDS2). There are 24 granules per 24hr interval, with a total data volume of 0.2GB/day. Fill values are reported at all invalid pixels, including pixels with 5 km inland. For each valid water pixel (defined as ocean, sea, lake or river, and up to 5 km inland), the following layers are reported: SSTs, ACSPO clear-sky mask (ACSM; provided in each grid as part of l2p_flags, which also includes day/night, land, ice, twilight, and glint flags), NCEP wind speed, and ACSPO SST minus reference (Canadian Met Centre 0.1deg L4 SST; available at https://podaac.jpl.nasa.gov/dataset/CMC0.1deg-CMC-L4-GLOB-v3.0 ). All valid SSTs in L3C are recommended for users. Per GDS2 specifications, two additional Sensor-Specific Error Statistics layers (SSES bias and standard deviation) are reported in each pixel with valid SST. The ACSPO ABI L3C SSTs are monitored and validated against iQuam in situ data in the NOAA SQUAM system https://www.star.nesdis.noaa.gov/socd/sst/squam . Quality of SST imagery and clear-sky mask is evaluated in the NOAA ARMS system https://www.star.nesdis.noaa.gov/socd/sst/arms .
