2nd GODAE Observing System Evaluation Workshop:
Towards Routine Monitoring


Session information and Draft Meeting Agenda

 

Presentations will be motivated with the following questions prior to the meeting:

Session 1: Overview of observing system components and activities (open session)

- What is the status, plans, progress, strengths and weaknesses of each platform?

Session 2: Assimilation diagnostics (open session)

- What assimilation diagnostics are currently computed from your system? How are they archived? How are they used? How could we use them to help monitor the GOOS?

- System overview:

  • Method (e.g. OI, Cooper and Haines, SEEK, EnOI, etc.)
  • What data are assimilated directly? with-held? super-obed?

- System diagnostics:

  • What diagnostics are computed routinely? (BG minus Obs, An minus Obs, biases, …);
  • How are they used/interpreted?
  • How are they archived?

- System performance:

  • When/where/why does the system perform well/poorly?
  • What are the known limitations/problems with the system?

- Do you already consider any diagnostics to monitor the GOOS?

  • to detect problems with instruments (biases etc);
  • to identify regions of the ocean that are under-sampled

Session 3: OSE/OSSE activities (open session)

- Presentations will be solicited from invited participants and others on recent OSE/OSSE activities

Session 4: How to move forward? (closed session)

- What can we, as the GODAE/OSE community, do to feed back information to the observation programs for the benefit of the broader oceanographic community? What is feasible? What is likely to be fruitful? Who will do what?

 

Draft Agenda

Day 1 - Thursday, 4 June 2009

09:00 Oke/Larnicol - Welcome and workshop objectives

Session 1: Introduction and Overview of observing system components (open session)

09:30 Schiller/Dombrowsky - Status of GODAE OceanView

09:45 Brassington – Status of JCOMM ET-OOFS

10:00 Lambin/Dibarboure - Satellite altimetry: status and products

10:30 Belbeoch/Viola - JCOMM-OBS international coordination and Argo and other in situ programs status


11:00 Coffee break


11:15 Cummings - GHRSST: status and products

11:30 Cummings - Forecast sensitivity: towards routine monitoring of the GOOS at NRL

11:45 Rabier - Lessons learned from THORPEX

12:30 Lunch

Session 2: Assimilation diagnostics and metrics (open session)

13:30 Weaver - Ensemble/Var diagnostics

13:50 Cummings - NRL

14:10 Drevillon - Mercator-Ocean

14:30 Lea - UK Met Office 

14:50 Brassington/Oke - BLUElink

15:10 Bertino - TOPAZ


15:30 Coffee break


16:00 Fujii - JMA

16:20 Larnicol/Guinehut – CLS

16:40 Weaver/Oke - Discussion

         What diagnostics are could be fed back to observational groups to support design,

         maintenance and justification for the GOOS? Can we coordinate our routine activities to

         help support each other and help improve our systems?
