assessment and policy user support
in Poland

Department of Atmospheric and Climate Modelling
Outline
• An integrated platform
• Policy support (new legislation introduced in 2018)
• Emission scenarios assessment
• Cooperation in Europe
• Capacity development
Modelling – Motivation
• To develop a state-of-the-art multiscale chemical-dynamical model of the atmosphere that will be used to :
• Study atmospheric chemistry in the context of air quality and climate change on urban, regional and global scales
• Facilitate chemical weather forecasting and data assimilation of chemical species
• Provide simulated atmospheric quantities (model atmosphere) for instrument design and retrieval algorithm testing
• To share the developed modelling system with other researchers, encouraging collaboration and training
The GEM model
Global Environmental Multiscale model
1. Highly flexible domain• Global
• Regional – i.e. NA, EU, Arctic
• Local – i.e. urban scale dx=250m
2. Weather and climate applications
3. Numerical efficiency and adaptation to new computational platforms
Model components and applications
• Transport processes• Chemical and aerosol processes specific to
• Air quality and anthropogenic emissions• Troposphere• Stratosphere & Mesosphere
• Air quality forecasting – Copernicus Services• Air quality assessment• Air quality episode studies• Environmental impact assessment of new technologies • Climate simulations
• Climate change adaptation scenarios • Impact of aviation transport on the atmosphere

Air Quality Modelling - policy support
Institute of Environmental Protection is responsible for modelling to support air quality policy for Poland
– new law introduced in 2018• Annual assessment (46 zones, including 30 urban areas)
• Transboundary transport assessment
• Representativeness of monitoring stations
• 5-year assessment for zone classification
• Decision support concerning National Air Quality Improvement Plan
• Operational air quality forecasting
Emission scenarios assessment
• Impact of electromobility development in Poland on AQ (2017)
• Analysis of the NEC Directive impact on AQ exposure in Poland and changes in transboundary transport
• Impact of GEOTERMIA Podhalańska S.A. on reduction of high pollution in Zakopane (geothermal household heating)

Cooperation in Europe
• CAMS_50 Regional Production• 4-day operational forecast for EU
• 10 km over EU, up to 5 km
• The day-before analysis + interim and validated reanalysis
• FAIRMODE (Forum on Air Quality modelling in Europe)
• Bilateral cooperation with neighbour countries (source attribution)
Application of satellite observations
Verification of sources and emission inventories
Application of satellite observations

CAMS_regional profiles
CAMS_50 Regional production
• GEM-AQ is one of two additional models in CAMS_50
• Setup consistent with the operational requirements (IFS, C-IFS forcing, emissions TNO-MACCIII + GFAS)
CAMS_50 Regional production
• Hindcast experiment from 1.06.2015 to 31.05.2016
• Validation using EEA measurements for O3, NO2, SO2, CO, PM10, PM2.5

European Arctic
• Global domain: • 356 x 320 grid points• 2.5 x 2.5 deg max. resolution
• Uniform core: • 200 x 200 grid points• 0.15 x 0.15 deg
• Model timestep 450 sec
• 28 hybrid levels
• Model top at 10 hPa
Synoptic context of aerosol transport episodes
30.04-5.05 – dust transport event at 700 hPa
Capacity development
• Development of an integrated environmental modelling and assessment platform (critical loads, health exposure)
• Application of satellite observations (emission verification, data assimilation, inverse modelling) • Sentinel 5p
• Sentinel 4 and 5
• Future plans• National model for regulatory purposes• Climate services
