PSD Flash Seminars: Observing the Arctic from the IASOA Observatories (Why does Taneil keep going to Siberia?)

Arctic change is a major topic of discussion for citizens, scientists, industries, militaries, and politicians around the world. This has not always been the case; 15 years ago, Arctic science was a small niche study area, especially for researchers that were inclined to travel to the Arctic and make direct in-situ measurements. Arctic field scientists face long, inconvenient and unpredictable conditions in every aspect of their work ranging from travel, expense, access to foreign territories, instrumentation designed for more benign operating environments, remote interactions with site technicians, communications, and organizing personal schedules. Despite this, the ground-based observations are critical for understanding the Arctic environment as models and satellites still have significant limitations in representing and characterizing what is really happening on the ground.

The May 12, 2014 PSD Flash Seminar (Starkweather*) described the programmatic structure of the International Arctic Systems for Observing the Atmosphere (IASOA) which is a consortium of Arctic Observatories that network to provide a pan-Arctic ground-based view of the Arctic environment. In this talk a number of analyses will be presented that show how data from the IASOA Observatories are addressing a wide range of research topics including distribution and trends of black carbon, radiation and heat flux surface-atmosphere exchanges, cloud and surface temperature linkages, upper air temperature trend statistics, ozone depletion events, and more.

Because the presenter has spent an inordinate amount of time at the Russian IASOA Observatory in Tiksi, Russia, time allowing, a brief slide show of “Life in Tiksi” will be used to conclude the presentation.
