Comment : Concept and objectives
The fundamental objective of the project is the further integration of existing European research facilities to a grid of reaction chambers in a continuation of the EUROCHAMP project. These facilities were created to study the impact of atmospheric processes e.g. on regional photochemistry, global change, as well as cultural heritage and human health effects under as realistic conditions as possible.
Although initial advances in the application of large chambers occurred in the United States and Japan, Europe now leads the world in the use of large, highly instrumented chambers for atmospheric model development and evaluation. Smaller chambers that were designed for specific purposes and are operated by experts in their fields excellently supplement the larger chambers. The integration of all these environmental chamber facilities within the framework of the EUROCHAMP-2 project promotes the retention of Europe's international position of excellence in this area and is unique in its kind worldwide.
The mobilisation of a large number of stakeholders dealing with environmental chamber techniques provides an infrastructure to the research community at a European level that offers maximum support for a broad community of researchers from different disciplines. The EUROCHAMP-2 project will foster the structuring effect of atmospheric chemistry activities performed in European environmental chambers within EUROCHAMP, since it offers the full availability of corresponding facilities for the whole European scientific community.
With respect to the project objectives mentioned above, three network activities, two joint research activities and a transnational access activity are formulated and cross-linked in the EUROCHAMP-2 project.
The major objective of the networking activities within the EUROCHAMP-2 project is to foster the effective interdisciplinary collaboration between the community of atmospheric scientists and colleagues from other disciplines that are closely related to it, which was successfully initiated within the EUROCHAMP project. This will be achieved through the three networking activities of EUROCHAMP-2.
The major objective of the joint research activities within the EUROCHAMP-2 project is the optimisation and further development of the infrastructures' performance. In order to meet these goals, two corresponding research activities are defined in the EUROCHAMP-2 work programme, namely the development and refinement of analytical equipment and the development of chemical and physical modelling techniques.
The infrastructure developed within the EUROCHAMP project has already been used by a large variety of scientists not only from the EU but also worldwide. Through the new transnational access activity the infrastructure will be opened more widely to attract even more colleagues from different disciplines related to atmospheric chemistry to make use of the infrastructure.

Comment : Three schools (Hight schools in Orleans and Tours, one elementary school in Bourges) were selected for twice 2 weeks continuous in-situ measurements (one in autumn / winter and one spring / summer, in order to characterize the seasonal dependence of the formaldehyde concentrations). An air flow modelling investigation will be first conducted for each site in order to better define the sampling points and the placement of the analytical tools. The use of the most advanced analytical tools with very high sensitivity and specificity (e.g. PTR-TOF-MS, and HCHO, NOx, O3 analyzers…) will enable us to draw a complete cartography of the pollutants in the sites investigated. The complementary laboratory studies will enable to identify the chemical species responsible for the secondary production of the formaldehyde. The obtained results will allow to propose recommendations useful for the reduction of HCHO concentrations in similar sites as those studied in this work.
Reactivity of Oxygenated Volatile Organic Compounds (ROVOC): Esters
Framework : CNRS/INSU (France) - DFG (Germany)

Laboratories :

Comment : Oxygenated volatile organic compounds (OVOCs) are omnipresent in the atmosphere. Esters (alkyl alkanoates, e.g. RC(O)OR, R = alkyl groups) are an important class of OVOC with both natural and anthropogenic sources. Esters made up of long chain carboxylic acids are the main constituents of animal- and plant-derived waxes and they also occur naturally in fruits and flowers. Various types of esters are used extensively by industry as solvents in chemical processing. The quest for renewable fuels has seen an increase in the use of biodiesel fuels, which typically consist of methyl and ethyl esters of fatty acids. Esters can also be produced in situ in the atmosphere from, for example, the oxidation of ethers. Few measurements of esters in the atmosphere have been made but those measurements, which have been made, confirm the presence of substantial levels of esters in the atmosphere.
Investigations on the atmospheric chemistry of esters to date have been limited to temperature dependent studies of the OH radical kinetics of a number of linear and branched alkyl acetates and room temperature studies of the products from the OH radical or Cl-atom initiated oxidation of a few of these acetates. Studies on methylacetate have shown that the product yield distribution is very temperature dependent. Although this limited set of data has been used to improve the structure-activity relationship (SAR) for alkyl esters at 298 K it is clear that there is a definite need for further refine of the SAR for esters particularly with respect to temperature dependence.
The project has the overall aim of improving the kinetic, product and mechanistic database for the reactions of OH radicals with a variety of esters as a function of temperature over the range 225-372 K and will use this information to further develop and refine the SAR for esters. The project will consist of the following components: i) determination of OH rate coefficients using absolute and relative methods as a function of temperature; ii) determination of the products of the reactions as a function of temperature and O2 partial pressure; iii) construction of explicit and simplified reaction mechanisms for models; iv) development of SAR for a wider range of ester types applicable over the temperature range 225-372 K.
