Short summary

A new inverse modeling and simulation system is developed to enable efficient and reliable transport simulations of volcanic SO₂ at large scale. The complex time- and altitude-dependent volcanic emission pattern of the Nabro eruption is identified by our inversion algorithm. The simulation results show good agreements with different satellite observations in terms of SO₂ horizontal distributions, and help to further reveal the complex transport processes such as the Asian monsoon circulation.
