To understand not just how, but why the Arctic system is changing, and to better serve the needs of stakeholders in the changing Arctic environment, an integrated spatial-temporal approach is needed. To this end, the International Arctic Systems for Observing the Atmosphere (IASOA) (www.iasoa.org) was developed to facilitate aggregating observational studies from stations (Alert, Eureka, Villum, Summit, Ny-Ålesund, Pallas, Sodankylä, Tiksi, Cherskii, Barrow, Oliktok) in the pan-Arctic region. The primary measurements made by the observatories are atmospheric: clouds, aerosols, radiation, chemistry, atmospheric structure and dynamics, and meteorology. These observations are considerably strengthened by co-located measurements of surface and sub-surface properties and adjacent Arctic Ocean measurements that allow studies of ice/ocean/land-atmosphere interactions and coupling. The IASOA consortium operates by promoting standardized measurement practices and data acquisition, data accessibility, and coordination of international science collaboratory working groups. IASOA is currently expanding into evaluation of observatory-based service products that can support human health, transportation and energy development. We invite contributions in the following areas that use data from the IASOA observatories:

1. Analyses of observations from two or more IASOA locations, including process studies, climatologies, and validation of reanalyses, prognostic models, and satellite products

2. Detailed studies of processes using multiple sensors at a single observatory that support process understanding of the Arctic atmosphere-terrestrial-cryosphere-ocean system

3. Analyses of observations from a single observatory that provide a template for a more pan-Arctic synthesis studies

4. Reports from projects and network organizations working to improve data accessibility and data standardization in the Arctic region

5. Reports on status and capabilities of the individual IASOA (and potential) IASOA observatories

6. Papers defining requirements of users needing information that can only be provided with Arctic atmospheric observational networks (for instance, experimental designs for the Year of Polar Prediction).

Contributions need not be from researchers actively engaged with IASOA. Although IASOA is an open consortium, recent publications indicate that a pan-Arctic and system approach to understanding the Arctic environment is being independently taken throughout the research community.
