The Group for High Resolution Sea Surface Temperature (GHRSST) is an open international science group that promotes the application of satellites for monitoring sea surface temperature (SST) by enabling SST data producers, users and scientists to collaborate within an agreed framework of best practice. GHRSST provides a framework for SST data sharing, best practices for data processing and a forum for scientific dialog, bringing SST to the user.

GHRSST is led by elected international experts: the GHRSST Science Team. The GHRSST Science Team co-ordinates the data production and related research. Continuous efforts to refine the GHRSST data management structures ensure a functional system that conforms to international directives and results in easy access and guidance for users.

Major stakeholders are represented in the GHRSST Advisory Council which advises the GHRSST Science Team on its strategy.

The GHRSST Project Office supports the smooth day-to-day working of the group.

Regional/Global Task Sharing

GHRSST developed the concept of a Regional/Global Task Sharing Framework (R/GTS), which established an international set of Regional Data Assembly Centres (RDACs), each of which delivers data to a GHRSST Data Assembly Centre (GDAC, online at and the regional user community.

Data are served from the GDAC to near-real-time users and applications for 30 days before the data are sent to the Long Term Stewardship and Reanalysis Facility (LTSRF, online at for long-term archive, stewardship, provision to delayed mode users, and future ECV/CDR production.

A key element of the R/GTS is the availability of data to users at all levels. The R/GTS framework is shown in the figure below.
