How warm the sea surface is (EWS-G2, geostationary) — EWSG2-NAVO-L2P-v01

In plain English

What it measures. How warm the sea surface is, measured along the satellite's view of the ocean. Coverage is over the Indian Ocean region, with both day and night readings (though daytime gaps occur where sun glare interferes).

How it's made. Calculated from infrared channels on the imager aboard EWS-G2 (formerly the GOES-15 weather satellite), which sits in a fixed spot above the equator, and packaged to a common sea-surface-temperature standard.

How & where you'd use it. Feeds weather forecasting and ocean monitoring, especially providing frequent sea-surface temperature snapshots over the Indian Ocean.

Official description

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.
