Data Fusion Quality Control User Applications To facilitate the movement of data

5. 5Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM The Issues GHRSST grappled with Different types of SST from different sources Skin Sub-skin Biased to buoy observations (~ 1m depth) Different sensor types Infra-red limited by cloud but offers fine spatial and radiometric resolution Microwave radiometers penetrate cloud, but have coarser resolution Different sampling characteristics Polar orbit, wide swath, ~ 1 km resolution (IR) Polar orbit, wide swath, 25 – 60 km resolution (MW) Geostationary orbit, ~ 5 km resolution (IR) Polar orbit, 500 km swath, 1 km resolution, high accuracy & stability (IR) Natural ocean – atmosphere variability Diurnal variability of SST Clouds Atmospheric aerosol Sea ice etc. Different SST product formatting

(1996)) Thermal structure of top 5m (from sub-skin to 5m) (From the PhD of A. Stuart-Menteth Temperatures at all depths collapse overnight to the same value at dawn The temperature at dawn (uniform through the top 5 m) is called the Foundation Temp. (SST fnd )

8. 8Villefranche sur Mer: 4th-6th Dec 2006Medspiration 4th and Globcolour 1st UCM The GHRSST solution Pre-process all L2SST datasets from different sources Add error statistics if not already present Add quality flags if not present Attach ancillary data that can inform the interpretation E.g., wind speed, solar radiation, atmospheric aerosol, sea ice Re package as level 2P in standard (netCDF) format Do this in near-real time Create match-up database (MDB) Pair all available in situ obs. of SST with coincident satellite data Create a high resolution diagnostic dataset (HR-DDS) Assemble extracts of all L2P data at specific sites for ease of intercomparison Perform O.I. analyses of L2P data to create L4 products Provide archive / distribution suitable for operational users Oversee quality assessment and reanalysis
