  1. COST 728 Enhancing Meso-Scale Meteorological Modelling Capabilities for Air Pollution and Dispersion Applications

  2. COST 728 Objectives (Selection) • Documentation of models, parameterizations, applications • Establish parameterizations which are poorly treated for air quality and dispersion modelling • Overview of strategies for integrating meteorological models (MetM) and chemistry transport models (CTM) • Examine ability and limitations of MetM-CTMs to predict pollution episodes • Recommendations for developing, running and validating air quality models • Identify main requirements for integrated modelling capability for Europe

  3. Warsaw Meeting – Technical tasks WG1 Parametrization Schemes • Maria Athanassiadou presented activities of WG1 • The workplan was presented, it was divided into the following tasks with leaders • T1.1 Surface processes, Task leader Ekaterina Batchvarova (NIMH) • T1.2 Boundary layer and turbulence, Task leader Maria Tombrou (Univ. Athens) • T1.3 Wet processes and radiation, Task leader Maria Athanassiadou (MetOffice) • T1.4 Applications, Task leader Ranjeet Sokhi (Univ. Hertfordshire)

  4. Warsaw Meeting – Technical tasks WG2 Model Interfaces and unification • Alexander Baklanov presented activities of WG2 • The workplan was presented, it was divided into the following tasks with leaders • Task 2.1, Off-line models and interfaces, Task leader Barbara Fay (DWD) • Task 2.2 Model down-scaling and nesting, including data assimilation, Task leader Alain Clappier (EPFL Switz.), with Maria Athanassiadou (MetOffice) as task deputy leader • Task 2.3 On-line coupled modelling systems, including feedback mechanisms, Task leader Jacek Kaminski (Univ. York), with Alexander Baklanov (DMI) deputy. • Task 2.4. Models unification and harmonization, Task leader Valentin Foltescu (SMHI)

  5. Warsaw Meeting – Technical tasks WG3 Model Applications • Mikhail Sofiev (FMI) presented activities of WG3 • The workplan was presented, it was divided into the following tasks • Task 3.1. Model review, documentation, databases etc. John Duros is task leader for the population of the database (http://www.cost728.org). • Task 3.2 Model examination • Task 3.3 Identification of limitations and potential methodology improvements • Task 3.4 Examination of model applications, case studies • Task 3.5 Link to climate modelling groups/link to end users

  6. Warsaw Meeting – Technical tasks WG4 Model Evaluation • Heinke Schlünzen (Univ. Hamburg) presented activities of WG4 • The workplan was presented, it was divided into the following: • Overview on tools and methods for model evaluation • Datasets for model evaluation (meta-data) • Tools and methods for user training • Recommendations for evaluation guidelines, aimed at developers • Documented framework for user training • Guidance for model results evaluation, aimed at end users and non-experts

  7. Swiss Contribution MeteoSwiss (with EMPA), PSI (with EPFL) • Meteorological pre-processor (interface between MetM and CTM) to generate parameters for dispersion models from LM • New turbulence parameterization for urban areas • Downscaling approach for dispersion-relevant parameters • Use of subgrid-scale variability of external parameters • Sensitivity of dispersion characteristics to sub-grid scale variability • Use of shallow convection parameterization for dispersion modelling • Testing of modelling system with real case applications • 2 PhD student positions still open!
