Reminder from KO - Objectives for R&D
Objective– Enhance and broaden the capacity of the modeling, assimilation
and monitoring components to improve product quality
Major issues– Ice modeling and ice data assimilation– Ecosystem coupling with the physical model– Modeling of the background error covariance matrix in data
assimilation– Prepare reanalysis system– Develop R&D tasks within NEMO
Outcome Expected for other WP: NWS, IBI, Med– Improve the capacity of the monitoring system– Incorporate outcomes of WP3

R&D : main achievements Preparation of the nominal modeling/assimilation systems
– V1: Global ¼° + Natl 1/12 nested + various upgrades• NEMO upgrade, biais correction, 3-hourly forcing, new bulk, EVP ice rheology,
new assimilation cycling, IAU, …– V2: Global 1/12°, Biogeochemistry (PISCES 1° coupled to the global ¼°)
• Long simulation produced and assessed Preparation of the backup system
– V1: Global ¼° + nested North Atlantic and Med 1/12° configs• NEMO upgrade, 3-hourly forcing, relax to OSTIA, new MDT, revisit the cov
computation, …– V2 (and +): CICE assessed, NEMOVAR developments
Preparation of the global ¼° 1992-2009 reanalysis– An ensemble of 3 reanalysis + 1 reference run without assimilation + one
observation-based product without model• Work on the model configuration: ORCA025 75 levels• Work on the ERA-interim flux corrections (radiative, precip)
Development of biogeochemistry at the Met Office (R&D) Comparison of different ice and biogeochemical models at NOCS Comparison of different global SST products at CLS Development of NEMO (optimisation, …) + configuration toolbox at CNRS

Reminder from KO - Objectives for Dev. & Maintenance
Objectives– Transition to operational mode the existing demonstration
systems (V0V1)– Enhance the capacity to incorporate R&D results (V0V2)
Major issues– System analysis to identify single points of failure and
develop redundancy on them (Backup developments)– Consolidation of interfaces with other TACs and MFCs– Adapt the system to yet-unknown users need (link with
WP16, WP17, and regional MFCs– Prepare the verification and validation, and produce the
system documentation (link with WP2)

MyOcean : Second Annual Meeting / 27-28 April 2011 / Roma
Dev. & Maint. : main achievements Maintenance of the V0 system Integration of the V1 (stream 1) nominal system
– New sub-system for the elaboration of the forcing fields (3-hourly)– New monitoring system + input observation QC system– New modelling and forecasting systems: regional nested into the global + other upgrades– Post processing to prepare the products (standard grids, regional tiling, …)– Integration of the MIS Gateway– Production of the technical documentation required– Transition of V1 into operation on operational computer resources
Integration of the backup V1 system– Archiving of NetCDF files– New post processing sub system– Output AMM BDY files for NEMO-SHELF– Integration of MIS Gateway– Production of the technical documentation required
Development of the CMCC PU for the dissemination of their reanalysis (Stream 2) Preparation of the V2 system
– Global 1/12, biogeochemistry, daily service + various upgrades, …

Reminder from KO - Objectives for Production
Objectives– Perform system operation to continuously deliver quality ocean
products in real-time– Produce reanalysis products for the altimeter period (1993)
Major issues– Transition to operational service (V0V1)– To Monitor, control and prepare the input data (links with TACs
and external data providers)– Ensure continuous production while system is upgraded
(transition process, V0V1V2, link with WP2)– Monitor (and improve) the production process quality– Maintain product repository and archive– Monitor the OLAs (links with WP16 and regional MFCs)

Production : main achievements
The V0 system has been operated regularly until its replacement by V1, delivering V0 services
The V1 system has been operated regularly since the end of last year, delivering V1 service– All the defined service processes are run since the launch of V1
• service monitoring reporting,• event, incident, change management…
Dissemination servers have been operated continuously (V0, V0/V1 parallel, V1)
Global reanalysis at ¼° (1992-2009) have been produced – 3 reanalysis, 1 forced reference simulation, 1 L4 product based on
the reprocessing of the observation (without assimilation)
V1 system operates as expected (availability and timeliness meet the specs)
No need to switch to the backup system have been identified

Reminder from KO - Objectives for Cal / Val
Objectives– Continuously monitor product quality– Collect downstream components feedback
Main issues– Generalise and systematise the validation methodology
developed in previous projects (Metrics)– Apply this methodology to the subsystem and its evolutions
(verification/validation process, link with WP2)– Ensure the feedback loop between downstream subsystems
and the global subsystem (adaptation, link with WP16 and regional MFCs)
Fitness for purpose issue

MyOcean : Second Annual Meeting / 27-28 April 2011 / Roma
Cal/Val : main achievements
Calibration (i.e. Verification in the V cycle definition)– Done once for new products– Compute static error bars– Calibration plan (ScCP)
• Defines the methodology– Calibration report (ScCR) delivered for acceptance
• Applies the methodology defined Validation (i.e. Validation in the V cycle)
– Done regularly for the real-time products– Compare the results obtained with a pre-defined reference– Validation plan (ScVP)
• Defines the methodology– Validation Report (ScVR) delivered at the PRR
• Applies the methodology ScCP and ScVP delivered for V1S1 and V1S2 acceptance ScCR delivered for V1S1 and V1S2 acceptance ScVR delivered for the PRR

Reminder from KO - Main Challenges
Scientific and technical Challenges– Keep as close as possible to the state-of-the-art in an
operational context
Operational Challenges– Ensure continuity of service with strongly evolving
systems
Ultimate Challenge– Meet users expectations in terms of product quality

MyOcean : Second Annual Meeting / 27-28 April 2011 / Roma
Future challenges
Manage releases in parallel to changes– Release: new products V1S1, V1S2, V2, system capacity
enlargement (e.g weekly daily service)– Change: upgrade the existing products/system
Adapt to the new V2 plans– Originally planned for the end of the project: April 2012– Now, to be accepted by September 2011: 6 month in advance
• 3-6 month development time lost: reanalysis ? Accommodate MyO release management with PU own release
management– Example the backup system major changes are planned after V2:
1st quarter of 2012 (Met Office constrains)• NEMOVAR, CICE, …
Availability of computing resources for the nominal– Existing resources reaching end-of-life– Next computing capacity upgrade planned not before 2013
