PACES is an emerging IGAC Activity that is being developed to develop collaborative research at the international level on Arctic air pollution. Arctic air pollution includes gases and particles that are sourced locally (from gas flaring or home heating, for example), as well as those that are transported to the Arctic over thousands of kilometres from sources in the mid-latitudes. At the Arctic surface, pollution concentrations reach a maximum in early spring - a phenomenon known as "Arctic haze". The effects of Arctic air pollution are manifold and substantial. Air pollutants in the Arctic can harm sensitive land and ocean ecosystems, as well as the health of local populations, and pollutants such as ozone and aerosol particles (especially black carbon, or soot), can modify the Earth's energy balance and enhance climate change in the Arctic. PACES aims to tackle key gaps in our knowledge on air pollution in the Arctic, including poor observational constraints and deficiencies in model representation of key chemical and physical processes. PACES will create new collaborative efforts between observational and modelling groups, social science researchers and local Arctic communities to address these issues.

A paper summarising the scientific issues and research needs related to PACES has been
submitted to Elementa (Arnold et al., 2015).

IASC/IGAC PACES workshop on Arctic Air Pollution
14 March 2016
Fairbanks, Alaska (during ASSW)
This workshop explored local Arctic air pollution issues and linkages between natural and social sciences including co-production of knowledge such as community-based monitoring approaches.
The discussions are being taken forward as part of a new PACES activity on Arctic Pollution and Societies. More information is available on the IASC website.
