The 4th PACES Open Science meeting will be held 26-28 May 2021 in an online format. We are planning for a more limited meeting than in past years, to account for the wide range of time zones that may wish to participate. However we still expect a full programme of science presentations across the full range of PACES science topics, and we will also make some time for virtual posters and discussion. We would also like to review progress across the PACES working groups, and provide opportunity for engagement in these activities. 

The meeting sessions will take place as follows:

26 May: 11:00-14:00 UTC
27 May: 12:00-15:00 UTC
28 May: 13:00-16:00 UTC

The programme will cover:  Arctic climate impacts of air pollution, Arctic-mid latitude linkages, long-range pollution transport to the Arctic, aerosol-cloud interactions in the Arctic, Improving observational capacity, Local Arctic air pollution sources and processing (including the forthcoming ALPACA project), Arctic urbanisation and air pollution.

As in previous meetings, the emphasis will be on getting together as a research community and sharing new analyses and progress on these different topics. 

Registration will open in mid-April, so please look out for a further announcement, which will also include a draft scientific programme and information on keynote speakers.  

Please save the date(s)! 

Best wishes,
Steve and Kathy, PACES co-chairs.

PACES is an IGAC and IASC co-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.
