The Group for High Resolution Sea Surface Temperature (GHRSST) was established in 2002 to foster an international focus and coordination for the development of a new generation of global, multi-sensor, high-resolution near real time SST datasets. It brings together international space agencies, research institutes, universities, and government agencies to collectively address the scientific, logistical and managerial challenges posed by creating the SST datasets and services within the Project. 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.
Large volumes of data and data services must be harnessed together to deliver the new generation of global coverage high resolution SST data sets that meet the GHRSST User Requirements. A basic 'version-1.0' of the Regional/Global Task Sharing (R/GTS) framework has been implemented in an internationally distributed manner. GHRSST datasets Global and regional coverage SST datasets are now produced by GHRSST RDAC Regional Data Assembly Centers (RDACs) in Australia, Japan, USA and Europe. RDAC SST datasets are passed in near real time to the operational GHRSST GDAC Global Data Assembly Center (GDAC) at the PO.DAAC where the are integrated together and served to the global application community. The GDAC plays an essential role in GHRSST quality control and data and metadata management.
