BACCHUS partners publish in Science and Scientific Reports

In January 2018 BACCHUS partners published articles in both, Science and Scientific Reports.
Jiwen Fan and Daniel Rosenfeld et al. published and article on "Substantial convection and precipitation enhancements by ultrafine aerosol particles" in Science. It has been long known that aerosol particle larger than about 0.1 micrometer serve as cloud condensation nuclei (CCN) and therefore have large impact on cloud properties and precipitation. The study revealed that when the CCN are scarce, as in pristine atmosphere such as in the Amazon, air pollution of ultrafine particles smaller than 0.05 micrometer can double the vertical winds that build deep convective clouds, thus inducing heavier downpours and possibly lightning from the polluted clouds. This means that little amount of emitted air pollution in the form of many ultrafine particles can have large impacts on precipitation and latent heating that drive the atmospheric weather systems, which have not been considered until now. This means that the formulation of numerical models for weather and climate prediction has to be revised to take the profound impacts of these tiny aerosols into account.

Erik Thomson (BACCHUS partner University of Gothenburg) and co-workers from BACCHUS partner J.W. Goethe University in Frankfurt, DE published "Intensification of ice nucleation observed in ocean ship emissions," in Nature's Scientific Reports. The report summarizes measurements of ice nucleating particles observed from ships transiting the Port of Gothenburg, Sweden. Direct comparisons to the clean background aerosol show that the sampled shipping emissions have enhanced ice nucleating properties. The observations connect with a previous BACCHUS modeling study by Possner et al. 2017, which illustrates such observations might have implications for environments with low particle concentrations and non-linear aerosol cloud feedbacks, like the Arctic.

Inter-journal Special Issue for BACCHUS articles set up

A special issue for BACCHUS publications has been created. It summarizes publications in the open-access journals Atmospheric Chemistry and Physics (ACP), Atmospheric Measurement Techniques (AMT) and Geoscientific Model Development (GMD) with their respective discussion journals. A description of the content and a list of the included publications can be found on the BACCHUS Special Issue's website.
