The GHRST-PP Validation Technical Advisory Group (VAL-TAG)
Validation of GHRSST-PP data sets and services is a complex task. The VAL-TAG is the team dedicated to the coordination of SST validation/verification and metrics activities to assure the quality and accuracy of GHRSST-PP products and services. The group is currently working to define a prioritised set of activities that will assist RDAC/GDAC and the user community. The MERSEA SST-TAC provides an example of L4 verification/validation monitoring activities. The ISAR AATSR validation program provides an example of in situ validation activities. To ensure standards are met in terms of validation measurements, several radiometer inter-calibration workshops have been run under the auspices of CEOS at the University of Miami.
Issues to be considerd by the VAL-TAG include:
- Validation methodology (using in situ observations)
- Inter/cross calibration of in situ observations including Black Bodies, radiometers, ships and buoys, ARGO and any other sources.
- Maintain links to CEOS WGCV/IVOS and other appropriate groups
- Provide support SSES teams and the GHRSST-PP MDB
- Report annually to the GHRSST-PP ST and to other bodies (e.g., CEOS) as required
VAL-TAG Membership
Membership of the VAL-TAG is open to anyone who has an interest in SST calibration and validation. A core group is now being convened to manage the activities and coordinatio of the VAL-TAG. Please contact Dr Gary Corlett (AATSR Validation Scientist) if you would like to contribute.
