DACCIWA Final Meeting in Yamoussoukro
On 14–17 October 2018, the final project meeting was successfully held in Yamoussoukro (Côte d’Ivoire at the Institut National Polytechnique Félix Houphouët Boigny - INPHB), organized by Université Félix Houphouët Boigny (Abidjan Côte d’Ivoire - UFHB) and the coordinating beneficiary Karlsruhe Institute of Technology.
The meeting showcased the richness of DACCIWA scientific results from the eight WPs demonstrating significant advances in our understanding of the boundary layer/low clouds, air pollution sources and levels, health impacts, atmospheric chemistry, aerosol-cloud and -radiation interactions, precipitation generation and connections to the regional monsoon circulation. The DACCIWA dataset is a unique and valuable resource that will soon become available freely to the scientific community. Even after the end of the project in November 2018 we will strive to advertise the dataset to create a long-lasting legacy of DACCIWA. At the same time, the presentations and discussions at the meeting revealed that even after DACCIWA the overall availability of scientific data remains critical, and that many scientific questions are still open, some of which were newly discovered in the course of the project. Both models and satellite data have issues that urgently need addressing. Among these open questions are important aspects such as the seasonality of health impacts, a quantification of the radiative impacts of aerosols on rainfall on a decadal timescale or reasons for the bad representation of low clouds in many weather and climate models. Many participants therefore expressed hope that we can maintain some of the momentum that DACCIWA has generated for follow-up projects that continue the established collaborations and lines of research.
