Near real-time (NRT) Global SST data (FRAC) from AVHRR onboard Metop-A,-B and -C are 
produced by NOAA using the Advanced Clear-Sky Processor for Ocean (ACSPO) SST system. 

Data are provided in GHRSST Data Specification v2 (GDS2) NetCDF format, as L2P (swath) and L3U (gridded, 0.02deg). 

A 2-week rotated buffer is organized by Platform/Level/YYYY/DDD. 

Further information on the data can be found at https://coastwatch.noaa.gov/cw_html/sst_avhrr_frac.html

The Reanalysis (RAN) product for AVHRR FRAC is under development.
