  1. Monitoring of ACSPOand IDPSSSTs in SST Quality Monitor (SQUAM) Analysis of one day of data – 12 August 2012 Presented at Program Review 9/21/12 www.star.nesdis.noaa.gov/sod/sst/squam/ STAR feedback to VCM

  2. NIGHT: ACSPO L2 minus Reynolds L4 12 August 2012 • Deviation from Reference SST is flat & close to 0 • Residual Cloud/Aerosol leakages seen as cold spots STAR feedback to VCM

  3. NIGHT: IDPS L2 minus Reynolds L4 12 August 2012 • More Cloud leakages in IDPS than in ACSPO • “Limb Cooling” – due to SST equations/coefficients STAR feedback to VCM

  4. NIGHT: ACSPO L2 minus Reynolds L4 12 August 2012 • Shape close to Gaussian • Domain & Performance Stats close to expected STAR feedback to VCM

  5. NIGHT: IDPS L2 minus Reynolds L4 12 August 2012 • IDPS sample +22% larger compared to ACSPO • Shape less Gaussian (negative Skew / increased Kurt) • increased Min/Max, STDV/RSD & Larger fraction of outliers STAR feedback to VCM

  6. NIGHT 12 August 2012 – Summary ΔT = “VIIRS minus Reynolds” SST (expected ~0) • IDPS SST domain +22% larger & Stats degraded, compared to ACSPO • Gap between Conventional and Robust stats wider in IDPS - More outliers STAR feedback to VCM

  7. DAY: ACSPO L2 minus Reynolds L4 12 August 2012 • Deviation from Reference SST is flat & close to 0 • Residual Cloud/Aerosol leakages seen as cold spots STAR feedback to VCM

  8. DAY: IDPS L2 minus Reynolds L4 12 August 2012 • More Cloud leakages in IDPS than in ACSPO • “Limb Cooling” – due to SST equations/coefficients STAR feedback to VCM

  9. DAY: ACSPO L2 minus Reynolds L4 12 August 2012 • Shape close to Gaussian • Domain & Performance Stats close to expected STAR feedback to VCM

  10. DAY: IDPS L2 minus Reynolds L4 12 August 2012 • IDPS sample +23% larger compared to ACSPO • increased Min/Max, STDV/RSD & Larger fraction of outliers STAR feedback to VCM

  11. DAY 12 August 2012 – Summary ΔT = “VIIRS minus Reynolds” SST (expected ~0) • IDPS SST domain +23% larger & Stats degraded, compared to ACSPO • Gap between Conventional and Robust stats wider in IDPS - More outliers STAR feedback to VCM

  12. Summary: 3/3Need help from PO and VCM Team • SST Team is interested in combining the Beta and Provisional processes together, in the interest of time. However, redesign must be completed before SST EDR is declared Provisional • SST EDR redesign needed before declaring provisional • Withdraw Bulk SST layer, write 0.17K delta to attribute • Reuse bulk SST layer to report first guess SST • Redefine Nighttime and Daytime SST algorithms • Reorganize SST QF code (More Readable/Maintainable) • Write out to SST EDR the VCM QF • Improve VCM performance for SST • Daytime VCM has large room for improvement • Nighttime VCM works better, but still outperformed by ACSPO STAR feedback to VCM
