Special sessions

Background and scope

This AQ special session is linked to the Pan-Eurasian EXperiment (PEEX;, which is a multi-disciplinary, multi-scale and multi-component climate change, air quality, environment and research infrastructure and capacity building programme ( It is originated from a bottom-up approach by the science community, and is aimed at resolving major uncertainties in Earth system science and global sustainability issues concerning the Arctic and boreal Pan-Eurasian regions as well as China. The programme solves interlinked grand challenges influencing human well-being and societies in Northern Eurasia and China, by establishing and maintaining long-term, coherent and coordinated research activities as well as continuous, comprehensive research and educational infrastructures. The PEEX approach is integrative and interdisciplinary and understanding that solutions to the interconnected environmental problems can be provided only by a seamless, harmonized and holistic comprehensive observational approach utilizing all available modeling tools representing different spatial and temporal scales.

This session is open to all researchers and users whom are interested in scientific issues such as air quality, climate change, biodiversity loss, chemicalisation, etc. as well as in-situ and satellite observations and multi-scale modelling of atmospheric composition as well as multi-level assessment on environment and population of the Northern Eurasia and China.

This session scope and aims to bring together researchers and users interested to (i) understand the Earth system and influence of environmental and other changes in pristine and industrialized Pan-Eurasian environments (system understanding); (ii) determine relevant environmental, climatic, and other processes in the Arctic-boreal regions (process understanding); (iii) maintain long-term, continuous and comprehensive ground-based, air/seaborne research infrastructures together with satellite data (observation component); (iv) develop new datasets and archives with continuous, comprehensive data flows in a joint manner (data component); (v) implement validated and harmonized data products in models of appropriate spatial and temporal scales and topical focus (modeling component).

List of topics included in special session:

  • Ground-based and satellite observations for atmospheric composition, datasets  using observations for Northern Eurasia and China;
  • Impacts on environment and ecosystems as well as on human health due to atmospheric transport, dispersion, deposition and chemical transformations of air pollutants in the Arctic-boreal regions and in Chinese.
  • New approaches and methods on measurements and modelling in AQ conditions in the mega cities;
  • Improvements anthropogenic emission inventories in polluted environments;
  • Aerosol formation and growth, aerosol-cloud-climate interactions, radiative forcing and feedbacks in Arctic regions and China;
  • Short lived pollutants and climate forcers, permafrost effects, forest fires effects;
  • Carbon dioxide and methane, ecosystem carbon cycle.

Submission of papers

Manuscripts may be submitted to appropriate journals such as Atmos. Chem & Physics special PEEX issue (

The transport emissions are a major source of pollution in urban areas. Due to technical development of fuel, engine and aftertreatment technologies, there is a constant change in emissions. The primary exhaust emissions are fairly well known, however secondary emissions formed from the gaseous precursors are poorly known. This knowledge is utmost important to establish mitigation methods as well as future policies and regulations. Also the role of non-exhaust emissions in urban air pollution is steadily increasing.

The session includes presentations from different transport modes, focusing on all aspects of primary to secondary and from exhaust to non-exhaust emissions. Both measurement and modeling results are welcome. Presentations related to transport policies and regulations are also welcome.

This will be a session devoted to the use of ML/AI methods, tools, applications and methodologies, in the area of air quality monitoring and modelling. Subjects may include:

  • AQ sensor profiling and calibration, with emphasis in low-cost sensors
  • AQ sensor network calibration
  • AQ data preprocessing, analytics and modelling
  • ML in data fusion for improved AQ estimations
  • ML and AQ dispersion modelling
  • ML/AI for remote sensing-oriented AQ estimations
  • IoT and cloud computing technologies in air quality


Session papers may be considered, after proper preparation and peer review, to be included as chapters to a book published by the Environmental Informatics and Modelling series, devoted to ML for air quality monitoring and modelling.

The quantiAGREMI project addresses NH3 and GHG emissions from Europe’s livestock farming. Financed by EURAMET, this project seeks to develop an SI-traceable field measurement infrastructure that is essential to reduce the large uncertainties of emission inventories in farming and that enables identifying and implementing effective mitigation strategies. To pursue this goal, 20 collaborating institutions build reference gas generators that provide dry and wet NH3 calibration gases and develop low cost GHG sensors for application on farms. Isotope techniques are applied to improve N2O inventories and micrometeorological methods used to identify NH3 footprints around farm buildings.

The session on quantiAGREMI will show results of measurement campaigns, developments of reference gas generators and sensors, and challenges met when quantifying NH3 in farm conditions.

Background and scope

Most of the world's population is exposed to poor air quality that exceeds WHO air quality guidelines. Along with air pollution, adverse impacts are increasing from climate change and extreme weather and affect towns and cities across the world. With increasing urbanization, cities in all regions are under significant pressure from multiple hazards driven by emissions of air pollutants and climate forcers. Climate change is also expected to increase incidents of extreme weather which, together with poor air quality, pose major challenges to formulating and implementing policy responses to strengthen adaptation and mitigation strategies.

We welcome abstracts to this special session that fall within the scope of atmospheric science and policy for clean air and carbon neutral cities. Specific topics that have a policy implication include but not restricted to:

  • Emission sources and chemical transformations of air pollution affecting urban areas;
  • Observational approaches to study air quality and climate, including for data scarce regions;
  • Multiscale modelling of air pollution and climate impacts for cities;
  • Integrated approaches to improve air quality and reach carbon neutral cities;
  • Reducing uncertainties in air quality and climate predictions and projections;
  • Interconnections between urban and regional scales affecting air pollution and weather;
  • Influence of climate change on cities such as extreme weather and air pollution;
  • Influence of urban planning for improving air quality and climate change adaptation;
  • Innovations in prediction, forecasting and control of air pollution in urban areas;
  • Analysis of urban hazards, such as, wildfires, dust intrusions, photochemical pollution episodes and thunderstorm asthma from pollen;
  • Analysis of measures for clean air and achieving carbon neutral cities;

Submission and review of abstracts

Abstracts should be submitted via the Conference website system and indicate that they wish it to be considered as part of this Special Session. All abstracts will be reviewed through the usual review process of the Conference.

The scope of this session is to discuss new developments in sensor techniques and data operation which enable air quality monitoring and personal air pollution exposure determination as well as new conclusions about sources of air pollutants and for emission reduction measures. Currently, people can buy air pollution sensors – this brings science into society. This exchange of information in the field of smart air quality networks use of crowdsourcing will show the possibilities to provide spatially complete information about urban air quality by online monitoring and necessary information for air quality managing. We are looking for new applications and research ideas.
