Ocean properties from polar orbit
(Aerosol/Cloud/Ecosystem ACE)

• What are the priority science uses of the new
  measurements?
• Surface Ocean Lower Atmosphere (SOLAS) science,
  foci 1 and 3
• gt examples (see next slide)

  ntation-strategy
• Aquatic photochemistry -gt CO2, CO, VOC gt add UV
  bands
• Photo-oxydation of DOM may be as large a source
  of CO2 as photosynthesis
• Emphasis on global and regional processes
• Specific geographic regions e.g., Arabian Sea
  strato-cumulus cloud-dominated areas
• Coupling between carbon and water/energy cycles
• Capability to measure fluorescence gt nutrient
  limitation
• Functional groups gt additional spectral bands

• What do we need to do scientifically to use these
  new measurements and/or to get ready for the
  mission?
• Coordinate the 3 ocean missions (ACE, GEO-CAPE,
  HyspIRI)
• Capacity development needed, i.e., enough
  scientists and infrastructure to support all
• In case of ocean color gap
• International collaborations established soon
  (with appropriate agreements on data exchange,
  calibration, validation)
• Define science program (field modeling studies)
  that maintain community focus on data continuity
  and mission foundations
• Ensure ocean instrument is scoped for enhanced
  capability, beyond currently available products

Ocean properties from polar orbit
(Aerosol/Cloud/Ecosystem ACE)

• Are there any major issues to be resolved before
  this science is enabled, and if so, what are they
  and what needs to be done?
• New, single atmospheric correction for ocean
  color and aerosols
• New observations in UV and SWIR gt new in situ
  instrumentation and calibration
  sources/methodologies
• Comprehensive cal/val, incl. vicarious
  calibration strategy
• Possible solutions for a data gap
• Biological/geochemical/optical time series at
  multiple ocean locations for scientific reasons,
  e.g., HOT, BATS, other
• Radiometric long term time series at single
  marine location
• Merge both options above at a single site
