IASOA Science

 

Figure shows a draft concept in development by Taneil Uttal.

 

Overview

IASOA Science employs surface-based, observational data from around the Arctic, to bound key Arctic atmospheric science questions such as:

-What are the impacts of short-lived climate forcers (SLCF's), like Black Carbon, Ozone, and Methane, on the Arctic climate system?

-What are the processes that control the formation, longevity, and physical properties of Arctic clouds?

-How do atmosphere-surface exchanges of energy and chemical compounds drive changes to the Arctic cryosphere (permafrost, snow cover, and sea ice)?

-What are the two-way linkages between Arctic-Global atmospheric exchanges?  

Our working group structure was developed to address these and other important questions.  Click a box below to learn more about the work IASOA is doing to advance science in these areas,  or select the graphic at left to learn more about the Arctic system science.

The figure depicts the system science complexities of the Arctic ecosystem, highlighting the role of the atmosphere in these processes (T. Uttal).  While many IASOA observatories have intensive observing for atmospheric properties, they are also platforms for cryospheric, terrestrial, and hydrological processes.  This co-location of multiple, long-term observing systems makes IASOA an ideal platform for developing interdisciplinary collaboration to investigate the evolving trends in Arctic processes. This is especially important in the Arctic where the physical processes of interest may not be static in the changing Arctic environment (Jeffries et al. 2013). A recent term that summarizes this concept is "emergent processes” which are resulting due to the non-linearity of the Arctic system.
