EUMETNET WG-ENV Activities to support Network of Atmospheric Services in GMES Sylvain Joffre Finnish Meteorological Institute POB 503 Helsinki, Finland EIONET- LaRochelle,

EUMETNET / WG-ENV (1997) Objectives: - To improve understanding and co-operation between Members in the environmental area; - To develop proactive co-ordinated relations with the EEA and other environmental organisations. Implementing Activities: Organise exchange of information and know-how between Members related to measurements and forecast in the environmental domain; Recommend practices and propose EUMETNET Programmes that would allow all European citizens to benefit from the best possible meteorological information pertaining to the environment (e.g., AQ forecasting); Maintain liaison with the EEA to serve its meteorological needs, and promote the European NMSs as providers of information and services to EEA Enlist the support of EEA for EUMETNET actions in favour of the environment; Maintain liaison with relevant COST Actions and other international activities. EUMETNET - EEA MoU signed on 4 September 1998.

WG-ENV Support to GMES Atmospheric Service WG-ENV activities in support of the GAS Workshop with EEA (April 2005): indication of substantial interest in collaboration of NEA’s and NMS’s in creating a real-time service Cooperation with GEMS and PROMOTE in identifying needs, challenges, partners, etc. Recommendation of EUMETNET Council (Oct 2005) that WG-ENV be involved closely with ECMWF in drafting background papers for making a case for the GAS. Interactions with other stakeholders: ECMWF, EUMETSAT, DLR, EEA, …. Stimulating the preparation of a COST Action for complementing GEMS and PROMOTE activities towards a European Network of AQFISs (ENAQFIS).

GMES Status GMES (Global Monitoring for Environment and Security) is an ESA-EC initiative and was launched in 1998; 2005: for practical reasons GMES Programme Office (GPO) concluded that only a few initial services can be launched as a start Three “pilot services” were selected and “fast-tracked”: Land Monitoring Marine (Core) Services Emergency Response Gradually, following these 3 fast-track pilot services, further services shall be implemented, based on user´s needs as identified and acknowledged by Member States and by the EC. EC R&D FP7 will provide funding for GMES. June 2005, GMES Advisory Council (GAC): several delegations desired to start looking into the possibility of an atmosphere-related service.

GMES Atmosphere Services (GAS) There is strong interest within the environmental and meteorological communities to address such a service. Preparation of an operational transition of GEMS in 2009 Scoping paper (May 2006) to build a case that “fully operational services” could be implemented by Sept. 2006; GAC: Workshop to be held in Dec involving relevant stake-holders. Preparation of an orientation paper for the workshop. Building on conclusions of Workshop => Implementation of respective operational services will then be prepared => pilot GAS in 2009.

Questions & Issues What shall be the scope of GAS ? -O3, Surface UV, Air Quality, Global & Regional Monitoring of Greenhouse Gases, Reactive Gases and Aerosols Find consensus on what the operational services can and shall be ? To be based on a Core Service architecture to produce basic global to European data sets. To feed a set of Downstream Services providing specific information at regional to local levels. Initially a subset of these services will constitute the GAS (should start their operational delivery by 2009) and from then onwards should be gradually complemented by additional services. Involvement & coordination of relevant players: EEA, ECMWF, GEMS, PROMOTE, ESA, O3-SAF, CM-SAF, NEAs, NMSs (WG- ENV), ….

AQFIS: Air Quality Forecasting & Information System i)Acquiring observational data (met+chem); ii)Processing and assimilating data into useful inputs/fields; iii)Forecasting the evolution of the dynamical and chemical state of the atmosphere (incl. emissions); iv)Post-processing and assessing models’ outputs; v)Exchanging, disseminating, and archiving shared data, metadata, and products; vi)Monitoring the performance against the defined requirements and intended benefits (mainly from users).

Motivation Legislation: to inform the public on AQ throughout the territory of MSs forecasting the AQ and exceedances of limit and target values, assess possible measures to abate exceedances using modelling tools Exists today: various national systems in terms of model tools, monitoring data and institutional arrangements EEA: data compilation for annual assessment through NRCs, near-real-time “Ozone on the Web” NMSs: weather data and modelling, development of tools and models, sometimes AQ forecast NEAs: dissemination of AQ information. Often AQ monitoring, sometimes AQ forecasts Extra complexity: AQ is an essentially trans-boundary phenomenon  limitation to a national approaches forecasting the AQ is more difficult and less accurate than e.g. weather prediction  single-model forecasts are uncertain

Motivation for ENAQFIS Today: patchwork of players: national systems in terms of model tools, monitoring data and institutional arrangements EEA/EIONET: coordination, AQ data exchange, compilation NMSs: weather data and modelling, development of tools and models. Infra. Data assimilation; Sometimes AQ forecast NEAs: dissemination of AQ information. Often AQ monitoring, sometimes AQ forecasts Legislation: inform the public on AQ throughout European MSs Forecasting the AQ and exceedances of limit and target values, Assess possible measures to abate exceedances using modelling tools Extra complexity: AQ is an essentially trans-boundary phenomenon: limitations from national approaches, ongoing international projects (GEMS, PROMOTE, SAFs, Forecasting AQ is more difficult and less accurate than e.g. weather prediction  single-model forecasts are uncertain.

NETWORKING national AQFIS-systems Existence of several National AQFIS with differing capacities, modalities, protocols and scientific bases ! => Need of: a European-wide “network of systems”, bringing together all players in the field and allowing for near- real-time (NRT) interactions and data flows, finally leading to an operational CW forecasting network Enhanced and structured dialogue, collaboration between the main actors involved. COST is a suitable neutral forum for the dialogue and for developing the basis of a chemical-weather forecasting “system of systems” in Europe.

COST Action Objectives To setup a forum for benchmarking, harmonising and developing approaches and practices for chemical weather forecasting network and near-real-time information systems in Europe. Identify needs for the optimisation and harmonization of exchange of AQ data & integration of modelling systems; Find out the gaps of existing knowledge and practices; Review the potential for and means of multi-model ensemble and chemical data assimilation; QA/QC criteria for CW forecasting systems; Assess visualisation and dissemination platforms, arrangements, formats and protocols; Build up on current systems, enhance cooperation and coordination between providers, operators, and users for improving the science and application of CW forecasting; Establish and/or strengthen links with similar ongoing national and international activities and dedicated projects

Scientific Programme Addressing the issues and barriers for the inter-operability of the various systems (various models, data storing, resolution,…). Towards agreeing on formats, standards and protocols for data and model result transfer and exchange. WP1. Exchange of AQ forecasts and input data: Requirements on data exchange frequency, formats, existing infras. Combining forecast data and NRT observations in a single system. Provisions for quality checks. WP2. Multi-scale forecasting, multi-model ensemble, boundary data Multi-model AQ assessments and forecasting. QA/QC issues. Ensemble. Feasibility of emission scenarios (short term abatement). Multi-scale CW forecast and assessment WP3. Dissemination and visualisation: Dissemination of AQ information to users. What to display, harmonization possibilities: separate pollutants vs. AQ index. Inventory of national systems, other activities and organisations. Cross-cutting activity: coordinate with other organizations (EEA, WMO, EUMETNET/WG-ENV, etc.) and ongoing activities (GEMS, PROMOTE).
