2012 Arctic Report Card

The latest Arctic Report Card was released at AGU on December 5.  Atmospheric results from the annual roll-up include updates on 2012 temperature anomalies as well as greenhouse gas and UV baseline measurements from Arctic observatories.  Observations show that increases from human sources in greenhouse gases continue, while warm air temperature anomaolies were relatively small compared to the last decade.  Click here for more information. 


Represenatives from the IASOA consoritum will travel to Vienna, Austra Nov 20-22, 2012 for the First WMO-GCW-CryoNet Implementation meeting to share IASOA experiences with network coordination in a pan-Arctic context and contribute to areas of common value for the co-development of IASOA and CryoNet.  Click here for more information and look for updates after the meeting.

New UNIS Course

The Arctic Atmospheric Boundary Layer and Local Climate Processes


Objective: After the course, the student will have an understanding of physical processes typical for the Arctic atmospheric boundary layer, how the Arctic boundary layer differs from that at lower latitudes; the challenges of taking meteorological measurements and a basic understanding of how numerical models in the Arctic work.


Registration Deadline: 15.Oct.2011

Sarychev Peak Eruption PDF Print E-mail




July 16, 2009

A July 4 article at shows sulfur dioxide (SO2) spread across the Arctic.  Notice the high levels over Greenland, the Candadian Arctic, Alaska's north slope, and the North Atlantic gyre.  (from the link, scroll past the Space Station Marathon and Sunspot Alert articles) 


July 15, 2009

According to the most recent entry in the CIMSS Satellite Blog (at later dates go to July, 2009 and read the July 13th entry),  a volcanic plume from Sarychev peak has been observed over the Great Lakes.  



Lidars at IASOA Observatories across the Arctic are detecting ash in the stratosphere from a Russian volcanic eruption.  Sarychev Peak, located in the Kuril Islands of Russia, has been erupting sporatically since June 11.  The latest strong eruption occurred July 12 and created a plume 17km high.  The eruption has manifested itself through the detection of ash layers up to 16km in the Arctic stratosphere, above average near surface aerosol optical depth (AOD) measurements, and the potential for cooler high latitude tropospheric temperatures.
