NASA SST ST, Miami, Nov 2011 Pathfinder, GHRSST, CEOS, and the SST Essential Climate Variable Framework Kenneth S. Casey 1 and Craig Donlon NOAA National Oceanographic Data Center 2 - European Space Agency

NASA SST ST, Miami, Nov 2011 In other words, a talk which will hopefully provide some context for broader international and CDR related activities.

NASA SST ST, Miami, Nov 2011 = The Committee on Earth Observing Satellites, the international coordinating group for earth-observing agencies.

NASA SST ST, Miami, Nov 2011 = The Group for High Resolution SST, the international coordinating group for SST.

NASA SST ST, Miami, Nov 2011 Where these two meet = the CEOS SST Virtual Constellation

NASA SST ST, Miami, Nov 2011 SST-VC: Implementation We proposed to implement the SST-VC building on the existing Group for High Resolution SST framework. (LTSRF)

NASA SST ST, Miami, Nov 2011 SST-VC: Implementation Using this approach, the CEOS SST-VC has instant access to: A baseline SST virtual constellation system of systems Internationally agreed SST products and services (data access, user support services) Initial consensus technical documentation for the constellation A functional coordination mechanism active at the international level (Science Team, Advisory Council, Project Office)

NASA SST ST, Miami, Nov 2011 CEOS benefits in many ways…  Strengthen CEOS Agency SST activities through better synergy and communication  Better SST product and service interoperability building on the strengths of CEOS Agencies  Facilitate better data access and product applications  Provide value for money by capitalising on the investments already committed to GHRSST  Allow a rapid spin up of SST-VC activities GHRSST benefits as well…  CEOS can encourage wider participation of all Agencies  Direct reporting of issues and requirements to principals Benefits of the Proposed Approach

NASA SST ST, Miami, Nov 2011 Initial Proposal accepted and Full Proposal submitted Membership updated based on agency review Review/Consideration by CEOS Plenary Implementation plan to be completed by the end of 2011 Now, why does any of this matter? SST-VC: Status Next week

NASA SST ST, Miami, Nov 2011 SST-VC: Proposed Activities

NASA SST ST, Miami, Nov 2011 SST VC participated in the first CEOS WGClimate meeting Miami Workshops to establish linkages to SI standards (NIST, NPL, QA4EO) ESA SST_cci established, team at work Contribution made to GCOS update of the Satellite supplement to the implementation plan Developing the CDR Data Processing Framework (DPF) to define the SST CDR vetting procedures Pathfinder v5.2 SST published in September in GDS2 format 6: Develop and Improve the SST ECV

NASA SST ST, Miami, Nov 2011 L4 L3 L2 L1 L0 CoarseLess Coarse FineFiner Fundamental CDRs Thematic CDRs SST_depth SST_fnd SST_subskin SST_skin CDR Data Processing Framework Established data management capability in the GDAC-LTSRF and GDS2 Defined the ECV conceptual “cube” of related SST CDRs (NO SINGLE SST PRODUCT CAN MEET ALL USER NEEDS!) But how to “approve” a dataset as a CDR? Science and application requirements Science and applications

NASA SST ST, Miami, Nov 2011 Define and document a clear framework for data providers who wish their datasets to be considered and evaluated as SST CDRs –Go beyond GDS2 format and the GDAC/LTSRF data management system Once defined and documented, build and support the framework CDR Data Processing Framework

NASA SST ST, Miami, Nov 2011 Include concepts from GCOS Climate Monitoring Principles, NOAA CDR Program, ESA CCI survey and Climate Ops model, GHRSST RAN-TAG Submission to intercomparison frameworks (e.g., GCOS SST and Sea Ice Working Group’s SST Intercomparison Facility, GMPE, SQUAM, HR-DDS, etc.) CDR Data Processing Framework

NASA SST ST, Miami, Nov 2011 Data assessed against independent, QC’d in situ SST (e.g. Argo, drifting buoys, depth SST from ships of reliable accuracy like IMOS ships) Data assessed against an established, traceable, reliable network of in situ radiometers (e.g. ISAR, M-AERI) Chris Merchant now leading the effort as the new CDR-TAG (formerly RAN-TAG) Chair CDR Data Processing Framework
