GHRSST Level 2P Sea Surface Temperature version 1.0 from the Electro-Optical Infrared Weather System Geostationary (EWSG2) produced by NAVO

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 2P sea surface temperature dataset produced by the Naval Oceanographic Office (NAVO) from the GOES Imager sensor on the Electro-Optical Infrared Weather System – Geostationary satellite (EWS-G2). The EWS-G2, formerly GOES-15, is the second Department of Defense owned geostationary weather satellite, which has been repositioned over Indian Ocean (IO) region at 60.0° West longitude in September 2023 and fully operational since December 3, 2023, providing timely cloud characterization and theater weather imagery to DoD. The EWS-G2 L2P SST product is calculated based on the 4-micron (band 2) and 11-micron (band 4) channels, providing nighttime and daytime SST. However, daytime SSTs are not produced in areas where the 4-micron channel is strongly affected by Solar radiation, which is defined by solar reflection angle > 50 degrees. The L2P data are packaged according to the GHRSST Data Specification version 2 (GDS2) in netCDF4 format at 0.04-degree spatial resolution and stored in 104 partial disks per day. The data will be continually updated with 24 hours latency.
