The GHRSST Reanalysis Technical Advisory Group (RAN-TAG)
The GHRSST Reanalysis TAG (RAN-TAG) is responsible for the scoping and implementation of GHRSST reanalysis (RAN) activities. The RAN-TAG is chaired by Dr. Kenneth S. Casey (Kenneth.Casey@noaa.gov) of NOAA's Natonal Oceanographic Data Center.
Membership
Membership in the the RAN-TAG is open to anyone interested in developing improved reanalysis climate data records for Sea Surface Temperature. Relevant activities include research and development of improved single-sensor reprocessing efforts as well as merged, multi-sensor analyses. If you are interested in joinging the team, please contact Ken Casey at Kenneth.Casey@noaa.gov.
Current membership of the RAN-TAG, as of 25 July 2007:
- Kenneth S. Casey, Chair
- Edward Armstrong
- Jorge Vazquez
- Craig Donlon
- Hiroshi Kawamura
- Gilles Larnicol
- David Llewellyn-Jones
- Nick Rayner
- Gary Wick
- Richard W. Reynolds
- Bill Emery
- Helen Beggs
- Gary Corlett
GHRSST Reanalysis Goals
- To create delayed mode Climate Data Record products with higher accuracy and consistency
- To link GHRSST reanalysis products to longer term climate records and historical SST reconstructions
- To enable a sustained reprocessing capability for both individual satellite sensor data and multi-sensor blended reanalysis products
GHRSST Reanalysis Requirements
- Spatial: Goal 4-5 km globally with 1-2 km regional products
- Temporal: Once per day
- SST Product Types: GHRSST Level 4 Foundation SST (L4 SSTfnd) (plus 4 diurnal offsets)
- Error Statistics: Bias and Standard Deviation at each output grid point
- Data Product Format: netCDF with CF metadata conforming to GHRSST Level 4 Specifications
GHRSST Reanalysis Activities
Activites of the GHRSST RAN-TAG are distributed globally but coordinated centrally at the GHRSST Long Term Stewardship and Reanalysis Facility (http://ghrsst.nodc.noaa.gov). Please see that site for additional information and complete access to all archived GHRSST data products.
