Model description

• Physics: COHERENS 3-D hydrodynamic model (V1, V2)– Developed in the nineties (MAST projects; Dr.P Luyten et

al.)– Verified/validated– Long list of users

• Biology: MIRO (Dr. Lancelot et al.)– 32 state variables– 28 processes linking the state variables– Phytoplankton , Zooplankton, microbial loop and benthic

diagenesis.– Hindcast run ’93-’06: validation against in situ and remote

sensing data using various metrics (see e.g., Lacroix et al., 2007, JMS 64)

Summary and next steps

Procedures for NRT validation do exist: Some are fully automatic Others are still in pre-operational mode For water level and SST (SSS?), we have enough data for some

statistical computation. For biochemistry, remote sensing data are sparse. Comparison

with climatology is possible at some stations For transports, NRT comparison between models is feasible.

Verification/validation of the MIRO&CO (pre-oper): more diagnostics, automatization of procedures, …

Must be done in compliance with Met. Office products.

Cal / Val practical plan

Proposal (to be discussed today)

• April: model outputs and data available• End of June: implementation of metrics• End of September: checking of the metrics

implementation• End of October: report and metrics code available
