PACES is an IGAC-sponsored initiative, which aims to review existing knowledge and foster new research on the sources and fate of Arctic air pollution, its impacts on climate, health, and ecosystems, on the feedbacks between pollution and natural sources, on climate responses, and on societal perspectives, including sustainability, adaptation and economic feedbacks. PACES coordinates international research efforts on these topcs in collaboration with existing and planned initiatives such as HTAP, AMAP, PEEX, YOPP, IASOA, MOSAiC and ArcticStar and motivates trans-disciplinary research related to Arctic air quality.
PACES is managed by three co-chairs and a scientific steering committee (SSC). There are two formal PACES working groups at this time.
WG1 is tasked with developing approaches to reduce model uncertainties regarding the processing and impacts of remote and local Arctic pollution sources. One approach currently under development is a targeted campaign using airborne and ground-based measurements to evaluate treatment of processes controlling evolution and loss of Arctic air pollution in models of climate and atmospheric composition, such as wet deposition.
WG2 focuses on the interaction between Arctic air pollution and societies. Approaches under consideration are observational studies guided by community concerns, investigation of local air quality in Arctic communities, and feedbacks between economic development, air pollution and environmental change in the Arctic.
