Historical simulation and volcanic eruptions at 15S and 40S in January, April, and July with specific dynamics

Simulations employed the CESM-MAM3 model to quantify stratospheric aerosol loading from historical volcanic and extreme wildfire emissions, with meteorological fields nudged toward MERRA2 reanalysis. Idealized experiments further included volcanic eruptions at 15°S and 40°S, each erupting in January, April, and July.本研究采用CESM-MAM3模型开展模拟实验，以量化历史火山活动与极端野火排放所引发的平流层气溶胶负荷；模拟过程中将气象场逼近至MERRA2再分析数据。理想数值试验进一步设置了南纬15°与南纬40°两处火山喷发场景，两处喷发均分别于1月、4月及7月进行。
