Democratic Republic of the Congo: This grant will support the first long-term PM2.5 monitoring network in DRC that will provide access to fully open data. By making this data openly available and collaborating with key stakeholders such as the Ministry of Public Health, The Kinshasa School of Public Health, University of Kinshasa, and others,  the work will provide decision-makers at all levels with actionable data and actively engage with the community to improve air quality across the Democratic Republic of Congo.
