EMPIR project organises session at European Geosciences Union General Assembly

Project consortium organises session on atmospheric gases and particles

EMPIR project Metrology for light absorption by atmospheric aerosols (Black Carbon, 16ENV02) has for the first time provided a clear route for the SI-traceable calibration of black carbon measurements, improving their accuracy and comparability. Black carbon, emitted from sources such as diesel engines and wood burning, is a major contributor to climate change, second only in importance to carbon dioxide. It is a primary component and key indicator of particulate matter, known to cause hundreds of thousands of premature deaths across Europe each year.

The improved measurements resulting from this work will be used to refine climate change models and mitigation proposals, and also improve the quality of conclusions from population studies investigating the health effects of air pollution.

Members of the project consortium organised a scientific session entitled Atmospheric gases and particles: metrology, quality controlled and measurement comparability at the European Geosciences Union (EGU) General Assembly in May 2020.

This session, with 23 abstracts and 70 attendees, provided an excellent forum for the dissemination of outputs from two other projects in addition to the Black Carbon project:

As a result of the COVID-19 pandemic and associated restrictions the conference was hosted virtually, no small undertaking since there were 18 036 abstracts in all.

This EMPIR project is co-funded by the European Union's Horizon 2020 research and innovation programme and the EMPIR Participating States.
