  1. WP 2 European ECV Capability and structured ECV Process Jörg Schulz, EUMETSAT

  2. WP 2 Partners and Tasks • Partners: EUMETSAT*, ITC, ECMWF, DWD, VITO, FMI, MTF • Task 2.1 Analysis of ECV capability and prioritisation for GMES climate services; • Task 2.2 Preparation of a white book for structured process to derive ECV data records

  3. Major External Events since Kick-Off • International Space week consisting of 3 meetings (Geneva 18-22 Feb 2013): • Architecture for space-based climate monitoring group • CEOS WG Climate • SCOPE-CM Executive Panel • GCOS Data Needs for Adaptation to Climate Variability and Change (Offenbach, 26-28 Feb 2013) • WCRP Data Advisory Council (Darmstadt, 4-5 Mar 2013) • GCOS AOPC (Geneva, 2-4 Apr 2013) • Major Points with relevance to CORE-CLIMAX: • CGMS/CEOS Data Record Inventory • Maturity Matrix Concept • Data Set Quality Assessments • New phase-2 SCOPE-CM projects

  4. WP 2 Deliverables

  5. WP 2 sub meeting on 19 March at EUMETSAT • We defined three elements for a capability assessment: • Data Record Inventories that contain technical specifications and also links to documented information on quality; • A System Maturity Matrix (SMM) that evaluates if the production of the ECV CDR follows best practices for science, engineering and utilisation; • An Application Performance Matrix (APM) that evaluates the performance of an ECV CDR with respect to a specific application. • In addition User Requirements for each application, Technical Specifications and validation and/or data quality assessment results for each record are needed to ‘measure’ the performance.

  6. CEOS/CGMS ECV Inventory Questionnaire • Joint activity of CEOS, CGMS and WMO in 2012; • Questionnaire form – addresses both existing and planned capabilities for data records in two separate questionnaires; • Areas: • General • Dataset Usage • Dataset Stewardship • Dataset Properties • Dataset Access • Results should describe the current and planned global capability on an ECV basis; • ECV inventory now contains ~ 215 records submitted for responsible organizations • CORE-CLIMAX uses it as a starting point on what data records are involved.

  7. EX CORE-CLIMAX MATURITY MATRIX DISCUSSION • CEOS WG meeting brought major points to the table from NOAA, ESA and GHRSST; • CORE-CLIMAX was offered and agreed to function as facilitator for further discussion during this year; • All players have slightly different targets for their development, i.e., different matrices may exist; • Agreement was on the fact what the maturity matrix can ‘measure’ and what not;

  8. New SMM Outline • Removed NOAA language; • Increased overall consistency of levels; • Introduced a feedback mechanism; • Attempted the usage for in situ data; • Etc. • Lets have a look. -> Excel File

  9. The CORE-CLIMAX System Maturity Matrix

  10. Example: Public Access, Feedback, Update

  11. Prerequisites and Needs for theApplication Performance Matrix • Needs useful User Requirements for an application that ideally provide 3 levels (breakthrough, target and optimum); • Needs useful technical specification and published validation results (ideally from data set quality assessments) for products assessed; • Need a weighting scheme for the columns as importance is different for different applications; • Need to define a function that maps distance to User Requirement into index 1-6; • Should jointly be populated by expert on data product and expert for application; • Result shall be an understandable message on the use of a data record for an application.

  12. The Application Performance Matrix (Draft)

  13. Example: Mid-Tropospheric Temperature Trend Product Technical Specification 1 anomalies are considered Requirements Table (ART) – Trend Analysis – Mid Tropospheric Temperature

  14. Example: Mid-Tropospheric Temperature Trend Leroy et al., 2008, J. Clim. 33 years 35 years 46 years

  15. Potential Mapping Function • In this case the mapping shall be based on the signal to noise ratio; • Following Ohring et al. (2005) a signal to noise of 5 is fulfilling the stability and random uncertainty requirement; • The mapping could be:

  17. Link to GCOS Climate Monitoring Principles

  18. GCOS Principles Satellite Specific

  19. CORE-CLIMAX Capability Assessment Workshop • Workshop is to: • Perform a self assessment using the new capability assessment tools and GCOS guidelines of each participating data record; • Perform independent (our SAG, ourselves and external experts) assessment of the same data records; • Discuss the assessment outcome differences and find consensus on the result; • Integrate the results into an electronic data base for EC and Copernicus; • The workshop shall discuss the initial report on the capability for the European Commission; • Proposed workshop date and venue: 21-23 January 2014 @ EUMETSAT
