Characterisation summary .

• Overall performance of SeaWiFS (against in situ)
  is better when compared to MERIS and MODIS-A.
• MERIS Lw670 has a better relationship (against in
  situ) than MODIS-A and SeaWiFS better Case 2
  retrieval?
• In Phase-2, the match-up statistics are improved
  compared to both the NASA-OBPG global validation
  (for SeaWiFS and MODIS-A) and GlobColour Phase-1
  characterisation results.
• The aerosol optical thickness (T865) match-up
  requires improved match-up criteria designed for
  in situ (water) rather than atmospheric
  parameters.
