Final Report Summary - AMIS (Fate and Impact of Atmospheric Pollutants)

Climate change, as well as environmental pollution and their possible effects on health, are pressing societal challenges. It is apparent that sustainable societal development cannot remain solely wealth-oriented, but must embrace an environmentally conscious agenda. Such an approach is possible if scientifically sound knowledge in all environmental areas becomes available to our societies and policy makers. A firm scientific basis to our understanding of the troposphere is of particular importance, as it contains the air that people breathe.
It is to address such issues that we aimed in the AMIS project to establish a long-lasting collaboration and create a network of European and Chinese research centres of excellence in the area of air quality and climate change studies. This aim has been achieved by undertaking joint research activities via collaboration facilitated by individual mobility of researchers between Europe and China. The AMIS network has contributed to:
- Strength and stimulate collaborative research between Chinese and European laboratories by exchange of experiences as well as optimisation of experimental techniques.
- Enhancing multidisciplinarity in the field of atmospheric chemistry by integrating experimental, theoretical and modelling competence from chemistry, physics, engineering, and meteorology in order to improve our understanding of the atmospheric system.
- Promote mutual awareness for the environmental issues addressed by our scientific community.

The established network is aimed at filling gaps in our knowledge in different areas which will increase our ability to further understand the atmospheric chemical processes impacting air quality and climate change.
To achieve these objectives, the AMIS project brought together a multidisciplinary consortium of chemists, physicists, and modellers, reflecting the interdisciplinary nature of this research which lies at the intersection of several disciplines such as physics, chemistry, engineering and meteorology. 15 research institutions from Europe and China have participated to the success of the present project: France (ICARE-CNRS/Orléans, IRCELYON-CNRS/Lyon, University of Bordeaux), Spain (CEAM-Valencia), Germany (TROPOS-Leipzig, FZJ-Juelich, KIT-Karlsruhe, University of Wuppertal), Denmark (University of Copenhagen), China (Fudan University-Shanghai, CRAES-Beijing, Peking University, RCEES-CAS/Beijing, GIG-CAS/Guangzhou, Shandong University-Jinan).

The project has reached an important number of scientific achievements related to atmospheric chemistry and air pollution based on laboratory and field studies. The following topics were addressed during the project:
- The oxidative capacity of the atmosphere and secondary organic formation with the focus on some highly polluted areas;
- Atmospheric Chemistry, transformation and impact of Persistent Organic Pollutants (POPs) and Polyaromatic Hydrocarbons (PAHs);
- Mineral dust aerosols (Chemistry and impact), source identification, interaction biogenic – anthropogenic particles, modelling of particle dynamics;
- Evaluation and investigation of the impact of the use of the photocatalytic materials on air quality;
- Evaluation of greenhouse gases emissions at the air / land interface in chosen Chinese and European sites.
The partners have conducted a number of joint laboratory studies and participated to field campaigns in different areas in China and Europe investigating photochemistry and particles characterization in the atmosphere (e.g. France and China (Beijing area and Yangtze River)). To this aim, instruments from different institutions, some of them built during the present project, were deployed. In particular, the new OH/HO2 radicals instrument (built jointly by FZJ-Juelich and Peking University) was used in 2014 and 2016 field campaigns in China. The Light Optical Aerosol Counter (LOAC) developed at CNRS (Orleans) has been used for months to characterize the particles at Shanghai and during the Yangtze field campaign (2015-2016).
Using highly equipped platforms such as simulation chambers and reactors, partners have investigated the atmospheric chemical processes controlling the degradation of anthropogenic and biogenic volatile organic compounds. These studies enabled the partners to derive the atmospheric lifetimes of the studied chemical compounds and derive their degradation products.
Investigations have been conducted to determine how the heterogeneous chemistry of ozone on mineral dust can globally impact the ozone cycle. This was done by measuring the uptake coefficient of O3 on Arizona Test Dust aerosols. While the uptake in the dark could not be measured, under UV-A irradiation, at atmospheric pressure, the uptake was enhanced depending on relative humidity and initial ozone concentration. The LMDz-INCA model estimation reveals the real impact of the photocatalytic ozone uptake on the concentration of tropospheric ozone. During night time around the arid and semi-arid zones, a reduction of 10% of tropospheric ozone was observed. Considering the sunlight effect, the reduction of tropospheric ozone concentrations could increase up to 50%.
Studies have been also conducted on greenhouse gases (GHG) emissions: CO2, CH4 and N2O, from natural ecosystems (mid latitude sphagnum type peatlands) an anthropogenized ecosystems (Cultivated soils) in response to climate changes and direct anthropogenic perturbations.
The work conducted with the support of the AMIS project showed also evidence of widespread ozone-induced visible injury on plants in Beijing and the effects of ambient ozone in China on snap bean genotypes by using ethylenediurea (EDU) was assessed.

The joint research activities within the AMIS project led to a large number of publications (23) and communications in international workshops and meetings (14) in addition to 3 co-supervised PhD thesis. Other scientific publications are foreseen in the near future. Moreover, partners from Europe have given a series of lectures and teaching classes to master and PhD students in China.

On the other hand, AMIS project has actively participated to the transfer of knowledge and training activities through organization of summer schools and workshops (http://era-orleans.org/irses-amis/events.php):
- 3rd Sino-French Workshop on Atmospheric Environment, Qingdao, September 10-13, 2012.
- 1st Sino-European School on Atmospheric Chemistry (SESAC, http://www.sesac.cn/), Taicang, May 17-27, 2013.
- 4th Sino-French Workshop on Atmospheric Environment (http://sfjw2014.sciencesconf.org/) Lyon, December 10-13, 2014.
- 2nd Sino-European School on Atmospheric Chemistry (SESAC2, http://sesac2.sciencesconf.org/), Shanghai, October 19-30, 2015.

The lasting collaboration between the European and Chinese partners is now insured through new partnerships programs between the different institutions involved in AMIS (e.g. French/German/Chinese programs, RISE program,...).

The obtained data during the project through laboratory as well as the field are of high interest to the scientific community in the understating of how the chemical processes studied will affect air quality and climate change. This understanding is important for the policy makers since it improves the used atmospheric models.
