Call for ACCENT Infrastructures is permamently open

The call for infrastructures is permamently open.

A number of research infrastructures (research aircraft, laboratory facilities, advanced analytical instrumentation and/or monitoring stations) are currently operational in Europe for atmospheric studies. New methodologies for the investigation of atmospheric mechanisms, generation of original and high quality data for modelling purposes have emphasised the need for advanced facilities over Europe. Except for a few co-ordinated international projects or already established European large-scale facilities, there is a clear lack of a co-ordination programme that would permit and simplify the access of all scientists to any research facilities within an extended European research area. For that purpose, a co-ordinated effort to establish a large-scale synergy allowing access to research infrastructures, diffusion of information and use of generated databases from a certain number of facilities would be extremely beneficial.

GEIA/ACCENT conference on emissions

The GEIA/ACCENT Conference on emissions will take place in Olso (Norway) on October 26-28, 2009.
Information on the preliminary program, abstract submission, financial support and registration are available on the GEIA wesite:

The deadline for abstracts submission is July, 1st 2009

The deadline for application for financial support is July, 1st 2009

The goal of the conference is to review progress in quantifying emissions of gases and aerosols and their uncertainties: presentations will focus on recent improvements in understanding emissions and using them in chemistry-transport, climate-chemistry and earth-system models. Past and future anthropogenic emissions, biomass burning and natural emissions will be considered, at both regional and global scales. The use of observations in the determination and evaluation of emissions and their trends will be reviewed. It is expected that the discussions, encouraged throughout the conference, will help improve the interface between emission datasets and atmospheric models. Emerging issues in the determination of emissions and their uncertainties will also be addressed.

Pilot on “Next Generation Summit”

The major objectives of the Pilot were (i) to plan on an event to be jointly organised between air quality and climate scientists, and impact specialists, and (ii) to develop web-based training material on the issue for the “ACCENT Virtual Knowlede Train”. An outreach activity (Café Scientifique) for the media, and an excursion to the Jungfraujoch research laboratory (3,580 m asl) complemented the programme.

Both ACCENT and ENSEMBLES scientists (from Europe / the USA) participated in the activity (download programme). Master students from Switzerland (University of Berne / ETH Zürich) assisted in the testing of the training material and provided valuable feed-back.

The event was organised by the University of Berne, Switzerland (Evi Schuepbach, ACCENT T&E Coordinator), and was linked to the Graduate School of Climate Sciences at Berne University (Master of Science in Climate Sciences Programme, Course No. S7453: Atmospheric Chemistry-Climate Links).

ACCENT T&E wishes to acknowledge the support offered from both Jungfraubahn AG, Interlaken, Switzerland and the International Foundation High Altitude Observatories Jungfraujoch and Gornergrat, at the University of Berne, Switzerland. We especially would like to thank Prof. Erwin Flückiger, Mrs Louise Wilson (both at Berne University), and Mr Felix and Mrs Susanne Seiler (at Jungfraujoch). We also appreciate the kindness of Mr Willi Seiler and Mr Wyss from Jungfraubahn AG, and of Mr Zumbrunn and Mrs Kaufmann (Gletscherrestaurant Jungfraujoch).

ACCENT Training Workshop in Guangzhou, China

An ACCENT T&E Workshop was held at Sun Yat-Sen (Zhongshan) University, Guangzhou, China, from 22-27 July 2009. The Workshop was integrated in a Summer School on Biodiversity organized by Prof. Shixiao YU, School of Life Sciences, Dept. of Ecology, funded by the Ministry of Education of the People’s Republic of China, and the National Natural Science Foundation of China. The ACCENT Workshop on “Changing Paradigms in Atmospheric Chemistry” focused on primary and secondary pollutants with respect to health and policy issues. It offered lectures and group work in both science and transferable skills including team building and leadership, interdisciplinary disagreement, media analysis, and science communication to non-scientists. About 150 postgraduate students from 40 Universities in China participated in the ACCENT Workshop that carried the sub-title “Learning about the Past for Leaders of the Future”. Lectures were given and group work was chaired by 6 European ACCENT scientists. About 10 policy makers from China were invited to a V.I.P. event on “Science to Policy” in the late afternoon-evening of 25 July 2009 in Dongguan city to exchange with early-career scientists who were selected among the 150 participating students on the basis of their leadership potential, innovation and creativity.

ACCENT Symposium – Presentations now available!!

ACCENT is pleased to announce that the presentations of its Symposium “Air Pollution – Climate Interactions. Contribution to European Policy Development” hosted by the European Commission, Directorate General for Research, in Brussels, 3-4 November 2009, are now available.

Click on the speakers name to download the pdf file of the presentation.

This Symposium brought together leading scientists in the field from Europe and the rest of the world and counted on the participation of high level representatives from the European Commission, EU Member States and International organisations. During the Symposium, the work accomplished in this field within relevant projects supported by the European Commission RTD Framework Program has been presented and debated. The Symposium aimed at contributing to the dialogue between science and policy and to provide the scientific basis to the policy making process in the fields of air quality and climate change.

We would like to underline the importance of this debate in this particular moment, when on one side most of EU Member States face difficulties to meet the requirements of EU Air Quality Directives and on the other side, there is a very strong need to arrive to a successful worldwide strategy in the coming COP 15 United Nations Climate Change Conference in Copenhagen (December 2009). Therefore, particular attention has been given during the two days event to the interactions (synergies and trade-offs) between the two policy areas.

The final Symposium programme can be found here.

Report on Gender Issues in Scientific Careers

The report WORKING AS SCIENTISTS: GENDER PERCEPTION OF THE WORK-LIFE BALANCE. ACCENT NETWORK: A CASE STUDY, on gender issues in scientific careers, is an ACCENT initiative on gender awareness themes, which focuses on the perception of gender differences and the creation of conditions for gender equality in scientific careers, analysing the experience of ACCENT scientists.

The work consisted in the elaboration of data collected from the wide ACCENT community through the completion of a questionnaire, elaborated by Fatima Farina, from the Faculty of Sociology of the University of Urbino, and revised by Eva Schuepbach and Michela Maione, for the ACCENT Gender Awareness Group.

The collected data have been analysed by Fatima Farina and Domenico Carbone (University of Piemonte Orientale), resulting in this interesting report which, we hope, will be food for thought for both men and women.

The report is available here.
