How warm the sea surface is, gap-free map (0.1 deg)

GHRSST Level 4 CMC0.1deg Global Foundation Sea Surface Temperature Analysis (GDS version 2)
ocean NASA POCLOUD Level 4 netCDF-4
In plain English

What it measures. A daily, gap-free map of sea surface temperature at about 0.1-degree resolution, giving a complete picture of ocean surface warmth with no missing patches.

How it's made. Produced operationally at the Canadian Meteorological Center by blending infrared and microwave satellite readings from several satellites with ship and buoy measurements, using the previous day's map as a starting point.

How & where you'd use it. Widely used in weather forecasting, ocean monitoring, and climate research where a complete daily temperature map is needed.

Official description

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature (SST) analysis produced daily on an operational basis at the Canadian Meteorological Center. This dataset merges infrared satellite SST at varying points in the time series from the Advanced Very High Resolution Radiometer (AVHRR) from NOAA-18,19, the European Meteorological Operational-A (METOP-A) and Operational-B (METOP-B), and microwave data from the Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the GCOM-W satellite in conjunction with in situ observations of SST from drifting buoys and ships from the ICOADS program. It uses the previous days analysis as the background field for the statistical interpolation used to assimilate the satellite and in situ observations. This dataset adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.
