What happened since the previous meeting?
• Feb-May 2021- website updates• June-Aug 2021: preparation for Szczyrk meeting• Sept 2021: announcement Szczyrk meeting• Oct 2021: 2023 meeting from Hokkaido to Obergurgl• Nov 2021: cancellation of Szcyrk meetingo Confirm Obergurgle meeting 2023
o Invite speakers and announce online meeting• Jan 2022: prepare funding applicationo Online meeting

Review of IASC NAG Objectives• NAG promotes interdisciplinary research for better understanding of Arctic regions• Promotes scientific activities at curcumarctic and international level• Supports early career Arctic scientists• IASC Working Groups represent different areas of research• NAG history:o Purpose is to address rapid changes in Arctic and international collaboration between
glaciologists, atmospheric scientists, oceanographers and others. Website has been
updated to reflect thiso Develop understanding of Arctic land ice and its role in global climate andenvironmental change• Annual workshop and meetingo 2-3d workshop on the dynamics and mass budget of Arctic glaciers/3h online meeting

Open forum meeting
Cross cutting activities usually includedObjectives• Present and discuss new research• Ordinate field work
• Future project ideas and collaboration• Networking opportunities especially for early career researchers
Chair is still Ward van Pelt, Vice chair remains Wesley Van Wychen
National contacts may change next year after moving to in person meetingso No suggestions for changes from audience today

Upcoming meetings• 2023 Jan 26-28: Obergurgl, Austria• Venue: University Centre• Local organizer: Jakob Abermann••

2024/25: Three candidates:
oHokkaido, Japan▪ Organizers: Shin Sugiyama, Masashi Niwano…
▪ Sapporo▪ Skiing near-byoObergurgl, Austria▪ Organizers: Jakob Aberman▪ Venue: University Centre is already reserved for Jan 21-25 in 2024
▪ Skiing also near-by▪ Austria is potentially easy access depending on your location▪ We must inform University Centre by end of 2022 as to whether we will keep the2024 reservationoSzczyrk, Poland• Mariusz Grabiec (niv of Silesia), likely in Szczyrk• Has been 30 years since first meeting in Wisla, reasonable price, potentially easy
access for some members• My wifi cut out for a minute here• (apologies for any misspelled names)

Voteoooooo

Japan 45%
Poland 38%
Austria 17%
Ward suggests we could do Japan 2024 and Poland 2025.
Action: We will have a re-vote in the near future as some members were not able toattend today
Audience suggests variation in meeting locations to encourage more diverse
contributions

Meeting format Ideas• Hybrid meeting ideas:o Hybrid light- physical meeting with recorded presentations that are made available
after the meetingo Hybrid medium: physical meeting with live streamed presentationso Hybrid plus: physical meeting with live streaming and digital contributions (virtualposter session)o Last year: hybrid medium was preferredo Next year: Obergurgl Austria can offer all of the above for freeo Ideas for next year's format: could combine hybrid light and mediumo Vote for next year's format:▪ Hybrid Light: 7%▪ Hybrid Medium: 61%▪ Hybrid Plus: 25%▪ Traditional physical meeting without hybrid: 7%
Backup plan
• Need contingency plan if can't have a physical meetingo Options: no meetingo Short online meeting like today
o Full online meeting (2-3d)o Vote:▪ No meeting: 0%▪ Short online meeting like today: 71%▪ Full online meeting (2-3d): 29%
Cross cutting activity and funding• In 2020 the IASC proposal on glacier-atmosphere interactions to IASC was funded. The activity
never took place and funding expires now• Action: IASC secretary suggests to submit a similar proposal in the new round with due date Jan31• Involves the IASC Atmosphere and Cryosphere WGs
o CWG: supported by Mariusz Grabiec, Wolgang Schoner, Shaewn Marshallo AWG: supported by Nina Petersen, Ewa Lupikasza, Jens Hesselbjerg, Thomas Kuln
(apologies for any misspelled names)
o Funding amount: 10,000 euro (3000e for logistics, 7000e for early career researchers)o Implemented as presentation and discussion sessions in Obergurgl, 2023
•Themes in glacier atmosphere interactions
1. Atmospheric circulation patterns and the impact on Arctic land-ice mass budget▪ Air circulation could affect temperature, glacier mass budget, black carbondeposition
2. Precipitation and snow fall in the Arctic- observing and modelling
3. Coupling of glaciers and atmosphere in general circulation models (GCMs), regional
climate modles (RCMS) and earth system modles (ESMs)

•••

No opposition from audience on these themes.
Suggestion to specify that glacier dynamic responses will also be examined- one of the weak
points of ESMs which don’t account for glacier dynamics
Action: We are looking for how to promote this, especially to atmospheric scientists and those
who have some connection to glaciology.
▪ Audience suggests advertising on ClimList, Atmospheric Working GroupWebsite• Nag.iasc/info• Recent changes:• Remove broken links, fix typos• Add recent developments ("About")• Turned the "Date" page into a link in Activities > Projects > MAGICS• Add report of 2021 online meeting ("Publications")• Add recent cross cutting activity proposals ("Publications")• Last year the idea to put a news section on the website was dismissed. Other ways to advertise
the NAG and its activities?
• Earlier (pre-summer) announcement on Cryolist?
• Newsletter for NAG enthusiasts (previous participants)?
• Audience suggests spring announcement

Other activities• Interdisciplinary Polar Studies (IPS-2022) modular meetings in Svalbard- for early career
researchers• Arctic Amplification - Glaciers - Environment• Includes field workshops• Discount for submitting papers to Remote Sensing journal for members of NAG
