February 2019 Quantifying and reducing the uncertainties of in situ aerosol absorption measurements with the extinction-minus-scattering technique Martin Irwin and Martin Beer Gysel of project partner PSI (Paul Scherrer Institut) presented an abstract derived from the project to the 2018 Cambridge Particle Meeting, held at the Cambridge University Engineering Department last June. The talk was well received at a meeting that since its inception in 1988, has grown to attract researchers in a wide range of aerosol and particle disciplines from around the world. Quantifying and reducing the uncertainties of in situ aerosol absorption measurements with the extinction-minus-scattering technique by Martin Irwin, Joel C. Corbin, Fengshan Liu, Rob Modini and Martin Gysel can be found here, and also over on our Documents and Publications page. January 2019 A Successful M18 Project Meeting for Black Carbon The Black Carbon project team in Braunschweig, Germany A successful M18 Black Carbon Project meeting took place in Braunschweig, Germany on the 5-6 December 2018. The meeting was hosted by project partner PTB. The partners came together to look at the work that had been completed between April – December on the project and also to look ahead at the work required towards M27 (September 2019). November 2018 Characterization of a new miniCAST with diffusion flame and premixed flame options: Generation of particles with high EC content in the size range 30 nm to 200 nm A new paper from the Black Carbon project has been published in the Aerosol Science and Technology journal. Characterization of a new miniCAST with diffusion flame and premixed flame options: Generation of particles with high EC content in the size range 30 nm to 200 nm by M. N. Ess, and K. Vasilatou of project partner METAS (Eidgenössisches Institut für Metrologie METAS) is available to download from Aerosol Science and Technology and also from our Documents and Publications page. September 2018 Black Carbon at the International Aerosol Conference Members of the project consortium were in attendance for the 10th International Aerosol Conference, September 2-7, 2018 at the America’s Center in St. Louis, Missouri, USA. Two posters were presented. The first poster; Laboratory-generated coated soot aerosols with tunable physical, chemical and optical properties using a CAST generator and a portable Micro Smog Chamber by M. N. Ess, A. Keller, A. Kimak, H. Burtscher and K. Vasilatou was put together by partners from METAS (Eidgenössisches Institut für Metrologie METAS) and FHNW (Fachhochschule Nordwestschweiz). The second poster; Characterization of a New MiniCAST Generator (Model 5201 Type BC) Offering Both Diffusion and Premixed Flame Options was put together by METAS. The IAC is held once every four years by an aerosol association on behalf of the International Aerosol Research Assembly (IARA), and rotates between Asia, Europe and America. The IAC attracts attendees from all over the world, sharing the latest in aerosol science and technology research. June 2018 Black Carbon at the 22nd ETH Conference on combustion generated nanoparticles Members of the project consortium were in attendance for the 22nd ETH Conference on combustion generated nanoparticles, June 18th – 21st, 2018 at ETH Zurich, Switzerland. Two posters were presented. The first poster Metrology for light absorption by atmospheric aerosols: The EMPIR Black Carbon project by Eija Asmi, Joel C. Corbin, Konstantinos Eleftheriadis, François Gaie-Levrel, Martin Gysel, Thomas Müller, Andreas Nowak, Konstantina Vasilatou, Ernest Weingartner and Paul Quincey provided a description of the aims and content of the project. The second poster; Characterization of a New MiniCAST Generator (Model 5201 Type BC) Offering Both Diffusion and Premixed Flame Options by M. N. Ess and K. Vasilatou was awarded with a poster prize. The ETH Conference on Combustion-Generated Nanoparticles serves as an interdisciplinary platform for expert discussions on all aspects of nanoparticles, freshly emitted from various sources, aged in ambient air, technical mitigation aspects, impact of particles on health, environment and climate and particle legislation. The conference brings together representatives from research, industry and legislation. December 2017 Black Carbon at the Monitoring Ambient Air 2017 conference Paul Quincey of project partner NPL, recently presented on the project at the Monitoring Ambient Air 2017 conference at the Royal Society of Chemistry. 2017 has seen issues relating to poor air quality which continues to remain high on the public and political agendas. While there is general consensus on the benefits of reducing ambient concentrations of nitrogen dioxide, ozone and particulate matter, there are many open questions about the priorities for maximum health benefits, the changing sources of these pollutants, and the best ways to reduce exposure to the public. All these questions need to be addressed using reliable evidence. Building on the success of this long-running annual event, and continuing the direct link with the work of Defra’s Air Quality Expert Group (AQEG), the conference presented an update on a range of relevant topics. As in previous conferences, the presenters included internationally recognised experts, providing a broad and up-to-date survey of the measurement, regulatory and scientific issues affecting air quality.
