The scientific scope of the Atmosphere Working Group includes scientific research towards understanding and prediction of Arctic change, and considering the fate of perennial sea ice and the global atmospheric consequences of its disappearance. This includes past climate states, investigation of Arctic processes across data sets and approaches, and climate model projections. The scope includes local and regional impacts of Arctic change.
The geographic scope of the Atmosphere Working Group shall be the Arctic but will also include the Arctic´s responses to global change processes (arctic amplification) and impacts of Arctic changes on the northern hemisphere atmospheric circulation.

Each Working Group has published a work plan to concisely articulate (with scientifically-driven high-level specifics, not programmatic detail) how they will achieve IASC’s vision over 5 years. These plans are meant to help Arctic scientists get involved in IASC activities, and it is expected that they will evolve in the coming years as the Working Groups continue with their work. The 2017-2022 Atmosphere Working Group Work Plan is available here.
The Atmosphere WG will address many of the direct large scale and regional climate change issues for IASC. We see our function as promoting science, but not focusing on monitoring or future assessments.
- Cloud, Water Vapour, Aerosols, Fluxes
- Arctic Air Pollution
- Coupled Arctic Climate System
- Arctic Weather Extremes
- Linkages: Role of the Arctic in the Global Climate System
These topics have been put under the three pillars of the Atmosphere Working Group: MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate), PACES (Air Pollution in the Arctic: Climate, Environment and Societies), and YOPP/PPP (Year of Polar Predictions / Polar Prediction Project).
