Annex I - “Description of Work”
Project acronym: MERSEA IP
Project full title: Marine EnviRonment and Security for the European Area
Proposal/Contract no.: FP6-502885
·carry out necessary R&D activities to determine the optimal way of deriving forcing fields from Numerical Weather Prediction
outputs (ECMWF analyses and forecasts) to drive the MERSEA
global ocean model, and validate it through impact studies using the
global ORCA2 mode (task 4.1),
·carry out necessary R&D activities to improve ECMWF wind stress and turbulent heat fluxes fields using relevant available high resolution satellite observations (scatterometer and microwave radiometer (task 4.2),
implement the near real-time access to the ECMWF outputs
and the first version of the surface forcing fields production
The programme for the build-up of the GMES pre-operational capabilities includes
+ 3D-InVar; variational method
using CTM very close to ECMWF model
CO2 tropospheric columns are being assimilated from AIRS infrared observations. Monthly mean distribution for May 2003
First analysis of stratospheric CO2 shows Brewer-Dobson type of circulation. Variability is also much smaller than in troposphere.

Current operational ozone monitoring capability is a good basis for developing a global capability to monitor reactive gases and associated aerosols
3.1 Integrate chemical modules with weather models, to provide global assimilation & forecasts of the distributions of
The global models can drive regional chemistry / air quality models.
The cost could be modest at 1 degree resolution
