  1. Aerosol-Cloud-Ecosystem (ACE)Ocean Productivity & Carbon Cycle WorkshopWelcome! Dave Siegel Director, Earth Research Institute UC Santa Barbara

  2. The Important Details • Bathrooms – down the long hall way • Logistics coordinator – Kris Duckett (kris@eri.ucsb.edu; 805-893-4885) • Wireless – network=icess, pword=ic3$$ic3$$ • Lunches – in group for all • Dinners – in group – tonite out & tomorrow catered affair at my house • Transportation – you’ve seen that by now

  3. Why are you here? • The ACE/PACE mission is supposed to provide climate/carbon relevant obs • Includes community level rates which are not part of conventional ocean color plans • The present ACE/PACE working group does not have appropriate expertise to do this • This meeting brings together experts in biogeochemistry & satellite ocean color

  4. Workshop Goals • Prioritize essential OPCC parameters for answering the ACE science questions • Review field, modeling & remote sensing methodologies for OPCC parameters • Identify path(s) forward for assessing OPCC parameters using satellite & other means • Propose a “cal/val” plan that includes OPCC parameters

  5. Deliverables (Sorta) • Assessment of essential OPCC parameters • Create OPCC product assessments • Discuss how OPCC parameters will be obtained during PACE/ACE • Create an OPCC “cal/val” plan • Write a high level document describing our approach for assessing essential OPCC parameters from satellite obs

  6. OPCC parameters • The PACE/ACE SWG has a handle on pools Chl, CDOM, IOPs, POC, PIC, PhytoC, DOC, PSD, PFT, etc. • It is the fluxes where we need help • Examples of OPCC parameters include… Net Primary Production (NPP), Gross Primary Production (GPP), Net Community Production (NCP), New Production, Export, Calcification, N2 fixation, Air-sea CO2flux, etc.

  7. What is a Cal/Val Plan? • Traditionally, goals were to calibrate satellite radiances & validating satellite data products Station approach measuring ocean reflectance & ocean properties (pools) Jeremy will talk more about existing NASA program We will skip the “cal” part in our discussions • OPCC parameters are more difficult to constrain Algorithms do not exist presently for many Time is an inherent variable in any rate process Likely will need modeling & process experimentation • The“cal/val/algo” plan must deal with this reality

  8. Today’s Agenda (1) ACE/PACE plans &science questions – Chuck Biogeochemical cycle overview for ACE – John   Satellite ocean color overview – DV Lunch (@12 downstairs – I hope) Regroup - discuss directions Present status of in situ science in support of satellite ocean color missions - Jeremy  Presentations by participants - 15 minutes max each  

  9. Today’s Agenda (2)

  10. Digital Info… • I’d like to collect everything • Will be posted at http://www.icess.ucsb.edu/~davey/OPCC
