3 www.cmar.csiro.au/staff/oke/ OSEval TT session agenda 0900Introduction (Peter Oke) Reminder of the OSEval TT mission Review of outcomes from GOV/CLIVAR Workshop Objectives of this session 0930NRT OSEs presentation (Matt Martin, for Dan Lea) Review of past NRT OSE results (Jan-May 2011); New results from recent NRT OSEs (June-October 2011); Proposal for NRT OSE results dissemination. 1000Discussion of NRT OSE activities (Discussion Chair: Peter Oke) Which groups will participate? How should NRT OSE results be disseminated? 33

4 www.cmar.csiro.au/staff/oke/ OSEval TT session agenda (cont) 1030GODAE OceanView’s role in supporting the XBT program Demonstrating the quantitative impact of XBT in model sis difficult because of the quantity of Argo data; Should all XBT data be with-held from operational systems and serve as the foundation of model evaluation and inter- comparisons? 1100Science presentations Speakers TBC 1200Close session 44

6 www.cmar.csiro.au/staff/oke/ Observing System Evaluation Task Team (OSEval-TT) 66 Routine Monitoring of the GOOS Routine Monitoring of the GOOS Delayed-mode OSEs and OSSEs for short-range and seasonal forecast systems Design and evaluation of new and future observation system components Provision and management of Observation Impact Statements (OIS) based on OSEval evidence Provision and management of Observation Impact Statements (OIS) based on OSEval evidence Capacity Building

7 www.cmar.csiro.au/staff/oke/ Framework for Ocean Observing: where GODAE OceanView fits 77 Contributed by E. Lindstrom, OOPC Chair, NASA GOV OSEval-TT

8 www.cmar.csiro.au/staff/oke/ OSEval TT mission Support observational agencies by demonstrating the impact of observations on forecast and reanalysis systems Contribute to the assessment of existing observing systems Identifying gaps and redundancies Identifying errors Contribute to the design of future observing systems e.g., altimeter constellations, mooring arrays etc

9 www.cmar.csiro.au/staff/oke/ NRT OSEs  Routinely run parallel forecast at operational centers and with-hold a different data each month:  Quantify the impact of each data type on forecasts  Multi-system approach  Rotating data types each month  We need to agree on:  experiment schedule (what to with-hold and when);  Who will participate?  Metrics (what?);  Analysis (what, who, how?); and  Dissemination (where, how?) 99

10 www.cmar.csiro.au/staff/oke/ NRT OSEs schedule  10 Jan 2011 Feb 2011 Mar 2011 Apr 2011 May 2011 Jun 2011 Jul 2011 : Dec 2011 Jan 2012 Feb 2012 Mar 2012 Apr 2012 May 2012 Jun 2012 Jul 2012 Argo XBT TAO Jason-2 All altims SST Argo : TAO Jason-2 All altims SST Argo TAO Jason-2 All altims  Proposed schedule for discussion  5 data types with-held
