Remarks

The Group for High-Resolution Sea Surface Temperature (GHRSST) provides a new generation of global high-resolution (<10km) SST products to the operational oceanographic, meteorological, climate and general scientific community. The overall aim of the GHRSST is to provide the best quality sea surface temperature data for applications in short, medium and decadal/climate time scales in the most cost effective and efficient manner through international collaboration and scientific innovation.

This class accesses L4 gap-free gridded SST products published in near real time by the GHRSST GDAC Global Data Assembly Center (GDAC) at the NASA JPL Physical Oceanography Distributed Active Archive Center (PO.DAAC). These products provide regional and global daily cloud-free estimates of SST at spatial resolutions ranging from 0.25 degrees to down 1 km. To fill in cloudy areas, data from multiple satellite and in-situ sensors are combined and regions without any data are filled in various interpolation and modeling techniques.

All products accessed by this class are published at a daily timestep. Some products are updated on a continual basis and available in near real time; others are updated infrequently and are intended mainly for historical analysis. The temporal extent, spatial resolution and extent, and sensors and interpolation technique used vary by product. All products use the WGS 1984 geographic coordinate system. GHRSST temperatures are published in kelvin. By default, this class converts them to degrees Celsius but provides an option to obtain the original kelvin values.
