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.

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
For more information about the
course and how to apply, see http://www.unis.no

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.
|
|
OVERVIEW
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.
