GHRSST Joint DVWG, HL-TAG & ST-VAL workshop28 Feb – 02 Mar, 2011, Boulder, CO The SST Quality Monitor (SQUAM) :an overview www.star.nesdis.noaa.gov/sod/sst/squam Prasanjit Dash1,2 and Alexander Ignatov1 1NOAA/NESDIS, Center for Satellite Applications & Research (STAR) 2Colorado State Univ, Cooperative Institute for Research in the Atmosphere (CIRA) Vision: A global, web-based, community, quasi NRT, one-stop monitor for SST producers and users !

  2. Contributions/Support • AVHRR Level 2 SST: • J. Sapper, Y. Kihai, B. Petrenko, J. Stroup:ACSPO (GAC: 5 platforms, FRAC: MetOp-A) • P. LeBorgne:O&SI SAF MetOp-A FRAC • D. May, B. McKenzie:NAVO SEATEMP • AVHRR Level 3 SST: • K. Casey, T. Brandon, R. Evans, J. Vazquez, E. Armstrong:PathFinder v5.0 • Level 4 SST products (additional L4 SSTs are being tested) • R. Grumbine, Xu Li, B. Katz:RTG (Low-Res & Hi-Res), GSI • R. Reynolds:OISST (AVHRR & AVHRR+AMSRE) • M. Martin:OSTIA foundation, GHRSST Median Product Ensemble • D. May, B. McKenzie:NAVO K10 • E. Autret, J.-F. Piollé:ODYSSEA • E. Maturi, A. Harris, J. Mittaz:POES-GOES blended • B. Brasnett:Canadian Met. Centre, 0.2 foundation • Y. Chao:JPL G1SST • L4s in SQUAM pipeline: • H. Beggs:ABOM GAMSSA • C. Gentemann:MISST • M. T. Chin, J. Vazquez, E. Armstrong:JPL MUR • M. Martin, J. Roberts-Jones:OSTIA reanalysis extended history (1985-2007) • GHRSST support: • Craig Donlon, Matt Martin, Andrea Kaiser-WeissAnd of course the ORGANIZERS: GC, GW, SC

  3. Objectives of SQUAM • Initial: • Monitor NESDIS operational AVHRR SST products in NRT • Heritage Main Unit Task (MUT, 2001-pr) • Advanced Clear-Sky Processor for Oceans (ACSPO, 2008-pr) for stability, self-consistency, cross-platform & cross-product consistency • Evaluate satellite SST products daily in global domain, against global L4 fields (e.g., Reynolds, RTG, OSTIA, ODYSSEA) – complements the validation against in situ SSTs (drifters, moorings etc…) • Quickly identify anomalies & facilitate product diagnostics (e.g., due to sensor malfunction, cloud mask, or SST algorithm) • Subsequent: • Other L2 (e.g., NAVO, O&SI SAF), L3 (PFv5.0) & L4 SSTs were included • Consequently ………..

  4. Current list of SSTs included in SQUAM • In pipeline (work ongoing): • L2 : SEVIRI (ACSPO & NESDIS operational) • L4: ABOM GAMSSA, REMSS MISST, JPL MUR • Locate this website: • Google: “NESDIS + SQUAM”, the first hit
