Comment on ‘‘Climate forcing by the volcanic eruption of Mount
[1] Douglass and Knox [2005, hereinafter referred to as DK], present an analysis of the observed tropospheric cooling following the 1991 Mt. Pinatubo eruption, and claim that these data imply a very low value for the climate sensitivity (equivalent to 0.6 C equilibrium warming for a CO2 doubling). We show here that their analysis is flawed and their results are incorrect. [2] We begin with a ve...
متن کاملClimate forcing by the volcanic eruption of Mount Pinatubo
[1] We determine the volcano climate sensitivity l and response time t for the Mount Pinatubo eruption, using observational measurements of the temperature anomalies of the lower troposphere, measurements of the long wave outgoing radiation, and the aerosol optical density. Using standard linear response theory we find l = 0.15 ± 0.06 K/(W/m), which implies a negative feedback of 1.4 (+0.7, 1.6...
متن کاملTriboelectric charging of volcanic ash from the 2011 Grímsvötn eruption.
The plume from the 2011 eruption of Grímsvötn was highly electrically charged, as shown by the considerable lightning activity measured by the United Kingdom Met Office's low-frequency lightning detection network. Previous measurements of volcanic plumes have shown that ash particles are electrically charged up to hundreds of kilometers away from the vent, which indicates that the ash continues...
متن کاملVolcanic Ash and Daily Mortality in Sweden after the Icelandic Volcano Eruption of May 2011
In the aftermath of the Icelandic volcano Grimsvötn's eruption on 21 May 2011, volcanic ash reached Northern Europe. Elevated levels of ambient particles (PM) were registered in mid Sweden. The aim of the present study was to investigate if the Grimsvötn eruption had an effect on mortality in Sweden. Based on PM measurements at 16 sites across Sweden, data were classified into an ash exposed da...
متن کاملIn situ and space‐based observations of the Kelud volcanic plume: The persistence of ash in the lower stratosphere
Volcanic eruptions are important causes of natural variability in the climate system at all time scales. Assessments of the climate impact of volcanic eruptions by climate models almost universally assume that sulfate aerosol is the only radiatively active volcanic material. We report satellite observations from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) on board the Cloud-Ae...
