On Friday19th October 2018 at 14 h 30 min, WASCAL Programme in Togo organized a restitution meeting of a Project on « Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA). Under the patronage of the EMbassy of the Federal Republic of Germany in TTogo, the Director of WASCAL Togo, Professor Kokou Kouami Hosted the Project’ stakeholders in the premises of the programme at the Université de Lomé.
The “Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) is a Project funded by the European Union. It aims to quantify the influence of anthropogenic and natural emissions on the atmospheric composition in West African countries and evaluate their impact on human health and ecosystems as well as regional meteorology.
Earlier in June and July 2016 an international consortium of sixteen (16) participants from two (2) countries in West Africa and four (4) European countries join efforts to conduct a large-scale field campaign around five (5) developing countries in West Africa. These countries include : Côte d’Ivoire, Ghana, Togo, Benin and Nigeria.
Togo played a very important role during the field data collection campaign, including the accommodation of three (3) research aircraft (one French, one German and one British) at the Lomé military airport as well as the operating center established at Omono Hotel in Lomé. In addition, researchers and operators involved in the DACCIWA Project worked closely with academic and operational actors (Meteorological Services, Air Control – ASECNA). The methodology of the first results are described in the following publication: https://journals.ametsoc.org/doi/10.1175/BAMS-D-16-0256.1
About two years after the campaign, DACCIWA Project stakeholders have proceeded to the communication and dissemination of scientific findings of their Project for the benefit of interested parties including government authorities, universities, meteorological services and commercial services. The Project conclusions focused on the following topics:
- Concentrations of pollutants in urban areas and their effects on health;
- Sources of urban pollution;
- Regional pollution and its impacts;
- The radiative effects of aerosols and their influence on weather and climate;
- The state of the atmosphere in the countries of South-West Africa in the future; and
- The shortcomings of current observations and models in the region.Prior to the WASCAL restittution meeting, the stakeholders met with the country’s authorities to present same campain results.
