  2. Science Highlights: FLH Behrenfeld et al., in preparation

  3. Science Highlights: FLH cont. Behrenfeld et al., in preparation High Fluorescence/Low Dust High Fluorescence/High Dust Fluorescence Yield (radiative) Dust deposition (mg/m2d) Low Fluorescence Fluorescence Yield: corrected for pigment packaging & nonphotochemical-quenching

  4. MODIS/Terra Analyses

  5. L2 L3 MODIS-Aqua Residual RVS - Lwn(412) +10% MS1 MS2 -10% Scan Pixel

  6. L2 L3 MODIS-Terra Residual RVS - Lwn(412) +10% MS1 -10% MS2 Scan Pixel

  7. L2 L3 MODIS-Terra Residual RVS - Lwn(412) MS1, Det 1-10 +10% -10% MS2, Det 1-10 Scan Pixel

  8. MODIS-Terra Residual RVS in nLw Before SeaWiFS-based Vicarious Characterization 412 443 488 After SeaWiFS-based Vicarious Characterization 412 443 488

  9. VIIRS Science Issues List not in priority order: -VisNIR IFA Optical Crosstalk - VisNIR ROIC Static Electronic Crosstalk - VisNIR Dynamic Crosstalk - LWIR/SMWIR Static Crosstalk &/or Ghosting - Gain Switch Thresholds, Noise, & Linearity - Stray Light Contamination - Reflective Band Uniformity - Emissive Band Calibration - Relative Spectral Response (RSR) - End-to-End (system level) Calibration - Sensor Stability (Temperature, SC voltage, EMI/EMC) - Response Versus Scan (RVS) Angle - Characterization of Polarization Sensitivity - Ambient to T/V to On-orbit Spatial Performance Delay in delivery of VIIRS FU-1 and launch for NPP (eight months) Ocean community request for FU-1 IFA replacement risk assessment denied. Items presently of particular interest to oceans.

  10. OBPG Data Set & Mission Support Activities • SeaWiFS • MODIS/Aqua: Ocean Color & SST* • MODIS/Terra: Ocean Color & SST* • NPP/VIIRS: Ocean Color & SST • Sensor & EDR algorithm performance • Launch in 2010 • Aquarius (data system): Launch in 2010 • Historical data • CZCS • OCTS • Sensor & mission concept development • Ocean Radiometer for Carbon Assessment (ORCA) • Aerosols, Clouds, Ecology (ACE) *Primarily data processing & distribution Reprocessing of all OC data sets planned for this summer.
