 Large volumes of data and associated data services are harnessed together to deliver the new generation of global coverage high resolution SST data sets.GHRSST is based on a distributed system in which the data processing operations that are necessary to operationally generate and distribute high resolution SST data sets having global coverage are shared by Regional Data Assembly Centres (RDAC).RDAC ingest, quality control and merge existing satellite and in situ SST data sources that are then merged to generate regional coverage SST data products having the same netCDF format specification (called L2P products), in real-time.
