Aerosol-Cloud-Ecosystem (ACE) Ocean Productivity & Carbon Cycle Workshop Welcome! Dave Siegel Director, Earth Research Institute UC Santa Barbara
The Important Details Bathrooms – down the long hall way Logistics coordinator – Kris Duckett 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
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
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
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
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, N 2 fixation, Air-sea CO 2 flux, etc.
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
Today’s Agenda (1) ACE/PACE plans &science questions – Chuck Biogeochemical cycle overview for ACE – John Satellite ocean color overview – DV Lunch 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
