-
- INTEGRATED PROJECT
-
- 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
10MERSEA Work Package 4 Forcing Fields
Objectives carry out necessary RD
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 RD
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
11MERSEA WP7 Modelling and Assimilation
- Objectives
-
- To perform research and development on
physical modelling, ecosystem modelling and data
assimilation as required for the operational
objectives of MERSEA during the whole life of the
project. - To provide all the necessary tools
(physical model codes, biogeochemical model
codes, data assimilation codes) that are required
by the MERSEA project to reach its operational
objectives. - To bring ad hoc scientific innovations
into the project and to gather all the relevant
European capabilities in order to make sure that
operational systems are maintained at the most
advanced level thus benefit from the progress
achieved in the research community, during the
project life-time and beyond.
12MERSEA TASK 11.4 SF2 Assessment of the impact
of MERSEA-¼ analyses on seasonal forecasts skill
- Lead ECMWF , Participants ECMWF, MF, INGV.
- Objectives
- To produce and assess seasonal
forecasts using the lower resolution coupled
models initialised with the interpolated Mersea-¼
analyses - Comparisons of seasonal forecasts
using the lower resolution coupled models
initialised with other existing analysis systems - Description of work
- Task 11.4.1 The available Mersea-¼ analyses,
appropriately interpolated using the
interpolation package developed in Task 11.3.1,
will be used for initialising the low resolution
coupled models. The hindcasts will cover the
period for which Mersea-¼ analyses are available.
These hindcasts will be assessed similarly to
what was done by the FP5 DEMETER project and
results compared to those obtained with the same
DEMETER project (ECMWF, MF, INGV).
13HALO Harmonised coordination of the Atmosphere,
Land and Ocean integrated projects of the GMES
backbone
- The programme for the build-up of the GMES
pre-operational capabilities includes - data delivery processes of observation systems
- interoperability and interconnection of the data
processing and delivery systems - organisation and system architecture.
-
- Key elements of the Land and Ocean IPs will be
dependent on the outputs of the Atmosphere IP.
The Atmosphere IP will be dependent on outputs of
the Land and Ocean IPs. -
- The HALO SSA will prepare the architecture and
system integration for the interacting part of
all 3 IPs into the GMES framework, and prepare
their joint transition to operational status.
14HALO Harmonised coordination of the Atmosphere,
Land and Ocean integrated projects of the GMES
backbone
- HALO will optimise the interactions of these
Segments of the GMES Backbone by formulating
agreed recommendations to the 3 IPs, and to the
GMES Steering Group in the areas of -
- scientific thematic analysis and coordination of
observational, modelling and data-assimilation
requirements for the interacting parts of the
IPs -
- cross fertilization of scientific thematics
leading to an improvement of knowledge, and
definition of the overall scientific
architecture -
- identification of shared issues in the areas of
data policy implementation, data acquisition,
data sharing and data dissemination, leading to
proposed candidate solutions analysis of the
candidate solutions, and - formulation of recommendations for a coordinated
transition to operations of the interacting part
of the pre-operational systems developed in the 3
IPs.
15HALO will focus on the interactions of
Atmosphere, Land, Ocean IPs
16HALO Planning Science Requirements, Candidate
Solutions, Recommendations
17Study Logic for the industrial studies
18Available Text on the Atmosphere IP
- Number of interactions influences the composition
and dynamics of the atmosphere and requires
efficient monitoring and assessment. Data
required to perform these activities are
available from satellites and from in-situ
measurements (in the atmosphere and on ground). - The objective is the integration and validation
of the available results in order to reach a
coherent and validated GMES infrastructure
serving the user community. Preference will be
given to an Integrated Project.
19GEMS (ii) Global Earth-system Monitoring
using Space and in-situ data
- GEMS data assimilation projects
- Monitor-GREEHOUSE GASES Monitor seasonal
variations of non-reactive Greenhouse Gases such
as CO2, CH4, N2O (CO) - Monitor-REACTIVE-GASES Monitor ozone and its
precursors, and sulphate aerosol and its
precursors. - Monitor-AEROSOL Model and assimilate global
aerosol information - Cross-Cutting projects
- SYSTEM-INTEGRATION Integrate the
data-assimilation sub- projects in a unified
pre-operational system - RETROSPECTIVE REANALYSIS Validate the
pre-operational system through observational
verification of retrospective analyses for the
"EOS - ENVISAT" epoch 2000-2007, and perhaps for
the epoch 1947-2007.

CO2 tropospheric columns are being assimilated
from AIRS infrared observations. Monthly mean
distribution for May 2003
22CO2 assimilation - Stratosphere
First analysis of stratospheric CO2 shows
Brewer-Dobson type of circulation. Variability is
also much smaller than in troposphere.

POLDER - Data Mgt tbd

25Aerosol modelling and assimilation is an emerging
issue for NWP
- HIRS channels sensitive to the surface
temperature, lower tropospheric temperature, and
moisture are subject to a 0.5 K or more reduction
in the brightness temperature during heavy dust
loading conditions. (Weaver, Joiner, Ginoux JGR
April 2003) -
- Aerosol is the biggest source of error in ECMWF
clear-sky radiation computations (JJ Morcrette,
pers.comm.)

28Global Monitoring / Forecasting of Reactive
GasesThe Chemical Weather Forecast
- 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 - ozone and its precursors
- sulphate aerosol
- other aerosol
- The global models can drive regional chemistry
/ air quality models. - The cost could be modest at 1 degree resolution

29GAW Network of world Stations
30Current status on GEMS Atmosphere
- The project is well-targeted
- The GHG, Aerosol, Integration, Re-analysis
sub-projects are of manageable and affordable
scope - Many institutes are keen to be involved in the
reactive gas sub-project, especially on
validation - If we do the essential work to build the overall
system, and support all interested parties for 3
years, then the budget will far exceed the
available funds. - We are about to survey all interested parties to
improve our budget estimates. - We may have to restrict participation by
validation partners to the latter part of the
project.
