Study models climate models’ ability to simulate aerosols in volcanic eruptions

The stratospheric aerosol model developed at the Finnish Meteorological Institute was part of a comprehensive study comparing the ability of advanced aerosol models to simulate the atmospheric properties of aerosols emitted in volcanic eruptions.

According to the study, while climate models are generally adept at modelling the transport of aerosols, they exhibit some drawbacks, such as overestimating the transport of aerosols to the Northern Hemisphere.
