The ERC-synergy project Q-Arctic (https://q-arctic.net/) aims to establish a next generation coupled land-surface model for the Arctic permafrost domain, explicitly resolving highest resolution landscape features and disturbance processes in the Arctic. To support this overarching objective, our first general assembly, to be held in Jena in November 2022, focuses on discussing future collaboration options with external project partners. In a hybrid workshop format, participants first report on their recent activities and future plans in relevant research fields. Subsequently, the group discusses common objectives, strategies for collaboration, and how to best divide up the related tasks between partners, both in breakout and plenary sessions.

Workshop time and place

Time: Nov 14 – 16, 2022 (Mon – Wed, noon to noon)
Where: Max Planck Institute for Biogeochemistry, Jena, Germany (auditorium)

Detailed scientific targets

Process modeling

Overarching: Discuss approaches for high-resolution modeling of Arctic domains using offline land surface models and ESMs.

High resolution modeling: what do we learn from regional case studies?
Data structure and data flow: What is the optimized setup for land surface models adapted to processes in the Arctic. What additional/refined input datasets will be required to inform a next-generation, very high-resolution model?
Conceptual advance: development of sub-grid scale hydrology for the permafrost region
Coupled modelling: feedbacks from land surface to the atmosphere – what is missing?
Statistical modeling approaches on few meter scale (e.g. thermokarst lakes) – scale which we will never get right on tile level

In-situ observations

Overarching: Develop strategies how the currently available Arctic-Boreal observational database, across measurement techniques, can be optimally synthesized to maximize information gain.

Ongoing efforts: What databases already exist that are generally available? Which group is underway of compiling new databases, with what specific target?
Planned efforts: What are databasing goals in the near future within the groups participating in the discussion? Are other efforts known that are relevant?
Collaboration strategies: Is there interest in combining efforts? How could the task of synthesizing data be shared between groups?
Ownership, user-rights: What aspects would need to be considered when aiming at building up databases that are supposed to be shared between groups, and eventually with the wider community?
Observation gaps: Can we merge efforts to close critical gaps in current databases, and enhance the representativeness of the existing observational networks?

Remote sensing

Overarching: Advancing circumpolar monitoring, contributing to and benefitting from community efforts

Review of focus sites: What are representative regions/sites for calibration and validation? What are site priorities from the side of modeling and in situ components?
Collaboration with drone observations: what is by now available internal/external? What are further plans, specifically type of observations? What is the utility of these data for satellite retrievals?
Contribution to/building on synthesis activities: What can we build on from other activities, especially the IPA synthesis activity on drained lake basins (DLB)? Could we contribute to a next level/phase of the DLB synthesis?
Synchronizing retrievals at circumpolar scale with external activities, especially AWI, Permafrost discovery gateway, Woodwell, Permafrost_cci
Further networking: What can we contribute to AMPAC, specifically wetland benchmarking and data collection? How can we benefit from AMPAC?

The Q-Arctic PIs are looking forward to your contributions to this workshop!
