The GHRSST Technical Advisory Groups or GHRSST TAGs are groups of experts who advise GHRSST on particular issues.

 

User Data And Services Technical Advisory Group (UDS-TAG)

Chair: Jean-François Piollé

The User Data and Services TAG was set up to review the report on the Evolution of Regional/Global Task Sharing (R/GTS) produced by the R/GTS Task Team.

Climate Data Records Technical Advisory Group (CDR-TAG)

Chair: Jonathan Mittaz

The GHRSST Climate Data Records Technical Advisory Group (CDR-TAG) coordinates the global production of SST Climate Data Records (CDR) extending back to 1981. Through interactions with the GCOS SST and Sea Ice Working Group, ESA’s Climate Change Initiative, the NOAA CDR Program, and members of the global climate SST community, the RAN-TAG has developed a comprehensive SST Essential Climate Variable (ECV) Framework for SST. This framework reflects the fact that no single SST CDR product can meet all users’ needs and illustrates the requirement for a coordinated suite of SST CDR products instead. The RAN-TAG works to ensure that all GHRSST operational and delayed mode data sets are archived and made available at the NODC LTSRF, and that the many groups developing CDRs around the world work together smoothly and efficiently, minimizing unnecessary duplication of effort and sharing scientific advances and product development experience.

Analysis And Intercomparison Technical Advisory Group (IC-TAG)

Chair: Toshio Mike Chin

The aim of the IC-TAG is to develop international collaboration for assessment and inter-comparison of the “gap-filled” SST products (L4 analyses), in order to provide uncertainty estimates on both the analyses and observational products and appropriate specification parameters (“spec”) for guidance to the users.  Past accomplishments from this TAG include the development of the original GHRSST Multi-Product Ensemble (GMPE) product.

Task Teams

Estimation And Validation Technical Advisory Group (EV-TAG)

Chair: Andy Harris

The development of Sensor Specific Error Statistics (SSES) is one of the activities of the Estimation and Validation Technical Advisory Group. This group was established to look at all aspects of satellite SST validation: from the reference data itself to the challenges which occur when comparing these locally representative reference observations to satellite data, to the ongoing refinement of the uncertainty estimates.
