Short summary

Using the NAME dispersion model in combination with high-resolution SO₂ satellite data from TROPOMI, we investigate the dispersion of volcanic SO₂ from the 2019 Raikoke eruption. NAME accurately simulates the dispersion of SO₂ during the first 2–3 weeks after the eruption and illustrates the potential of using high-resolution satellite data to identify potential limitations in dispersion models, which will ultimately help to improve efforts to forecast the dispersion of volcanic clouds.
