Polar processes and research have come to the fore in the recent decade because of the rapid changes occurring in the Arctic and because of their potential for high global societal impacts. The Arctic regions show the greatest observed warming compared to the rest of the globe and are projected to have the greatest change in a warming climate. The Arctic research emphasizes understanding processes affecting the surface energy budget of the Arctic, both over the pack ice as well as at terrestrial locations. These processes include cloud-radiation and cloud-albedo feedback processes, boundary and surface-layer heat exchange processes, and mesoscale/synoptic scale dynamical processes. It also includes linking the atmospheric processes with processes in the upper ocean and upper soil regions. Research focuses on undertsanding these processes and how the process interactions produce changes or trends that are important for the regional or global weather and climate on both short and long time scales. Several existing polar research data sets are available for study including SHEBA, AOE-2001, ASCOS (2008), ACSE (2014) and SeaState (2015), all obtained over the Arctic Ocean. Our polar group also process and analyze data from the international IASOA sites. These are long-term, polar climate monitoring terrestrail sites, and include Barrow, Eureka, Alert, and Tiksi. Topographical and coastal processes also influence these sites and are key topics for study. New remote sensing data from the Greenland Summit site are also available for proposed studies. Our group takes the approach that observations are key for understanding processes and process interactions, but that models are necessary to provide more complete understanding of these interactions. This use of models requires careful model validation with available observations, and we encourage development of innovative validation techniques.

The ESRL PSD Polar Observations and Processes group has extensive interactions with other ESRL/PSD groups. In the Arctic research program, opportunities exist for involvement in future measurement campaigns, analysis of existing or future data sets, numerical modeling of idealized and case-study scenarios for process understanding (primarily using WRF in mesoscale atmospheric mode, LES mode, and coupled air-ice-ocean mode), validating existing weather or climate models, and developing new weather and ice forecasting techniques.
