  7. DATA FLOW

  8. Venice • Rehearsal • July 10th, 2011 image • GTP access has been down since Friday (July 15th) Chlorophyll-a and a_443 Image Difference and scatter plot examples

  9. July 10, 2011 VIIR and MODIS processed VIIRS MODIS http://www7333.nrlssc.navy.mil/browse/lvl3/modis/AAOT/2011/jul/?F=1&C=N&O=A&V=0&P=*chl* http://www7333.nrlssc.navy.mil/browse/lvl3/viirs/AAOT/2011/jul/?F=1&C=N&O=A&V=0&P=*chl** Example of Chlorophyll. All products processed Remote sensing reflectance.

  10. Scatter plot MODIS Chl - VIIRS Chl Difference Plot July 10, 2011 - Venice VIIRS – CHL MODIS – Chl mg/ m^3 MODIS Chlor http://www7333.nrlssc.navy.mil/browse/lvl5/modis-viirs/AAOT/2011/jul/?F=1&C=N&O=A&V=0&P=*chl*eps

July 10, 2011 VIIR and MODIS processed VIIRS MODIS http://www7333.nrlssc.navy.mil/browse/lvl3/modis/AAOT/2011/jul/?F=1&C=N&O=A&V=0&P=*chl* http://www7333.nrlssc.navy.mil/browse/lvl3/viirs/AAOT/2011/jul/?F=1&C=N&O=A&V=0&P=*chl** Example of a_443 (QAA). All products processed Remote sensing reflectance.

  12. Example from Venice – Matchup • Monitoring the Channel Gains • In all regions MODIS Chlorophyll VIIRS – Proxy Channel Gains

  13. MODIS VIIRS – Proxy Channel Gains
