Volcanic eruptions can alter the state of the stratosphere on a timescale of several months to years and can have a significant impact on radiative forcing especially in the climatologically sensitive Arctic regions.The eruptions of the Kasatochi volcano in August 2008 and Sarychev volcano in June 2009 led to an enhanced stratospheric aerosol load which was studied with the Koldewey Aerosol Raman Lidar (KARL) at the AWIPEV Arctic Research Base in Ny-Ålesund, Spitsbergen at 78.9 N, 11.9 E. In both years, distinct layers of enhanced aerosol backscatter in the lower stratosphere and the tropopause region have been observed on subsequent days coinciding with a significant increase in aerosol optical depth (measured with sun photometer) compared...
