متن کاملAtmospheric impact of the 1783–1784 Laki eruption: Part I Chemistry modelling
Results from the first chemistry-transport model study of the impact of the 1783–1784 Laki fissure eruption (Iceland: 64 N, 17 W) upon atmospheric composition are presented. The eruption released an estimated 61 Tg(S) as SO2 into the troposphere and lower stratosphere. The model has a high resolution tropopause region, and detailed sulphur chemistry. The simulated SO2 plume spreads over much of...
متن کاملSynchronous deposition of volcanic ash and sulfate aerosols over Greenland in 1783 from the Laki eruption (Iceland)
[1] Sulfate aerosols from the 1783–1784 A.D. Laki eruption are widely used as a reference horizon for constraining Greenland ice core time scales, yet the timing of the arrival of the sulfate remains under discussion. Two ice cores from western Greenland, analyzed with high temporal resolution, confirm that sulfate aerosols arrived over Greenland late in 1783, concomitant with the tephra, eleva...
متن کاملSulfur isotope evidence of little or no stratospheric impact by the 1783 Laki volcanic eruption
[1] Historic records and research have suggested that the 1783–1784 eruption of the Laki fissure volcano in Iceland impactedNorthernHemisphere climate significantly, probably as a result of the direct injection of volcanic materials into the stratosphere where the volcanic aerosols would linger for years to cause surface cooling across the Northern Hemisphere. However, recent modeling work indi...

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The long 1783–1784 eruption of Laki, in southern Iceland, was one of the first eruptions to have been linked to an observed climate anomaly, having been held responsible for cold temperatures over much of the Northern Hemisphere in the period 1783–1785.
