This project will model the Laki volcanic eruption in Iceland in 1783-1784 in order to assess the impact of high latitude eruptions on the climate system. Historical data are sufficiently detailed to permit an estimate of the radiative forcing arising from the eruption with a high degree of confidence. Estimates of gaseous and particulate emissions will be fed to an atmospheric circulation model and its results compared with observations.Broader impactsThe opportunity to explore the impact of volcanic eruptions on the polar troposphere has wide-ranging benefits to the scientific community and public alike, since the Arctic is extremely sensitive to even small changes in climate, whether they are natural or anthropogenic in origin.

该项目将模拟1783-1784年冰岛拉基火山爆发，以评估高纬度火山爆发对气候系统的影响。历史数据是足够详细的，允许估计的辐射强迫所产生的喷发具有高度的信心。对气体和微粒排放量的估计将输入大气环流模型，并将其结果与观测结果进行比较。更广泛的影响有机会探讨火山爆发对极地对流层的影响，对科学界和公众都有广泛的好处，因为北极对即使是很小的气候变化都极为敏感，无论这些变化是自然的还是人为的。
