Short summary

A method to form SO₂ profiles in the stratosphere with high vertical resolution following volcanic eruptions is introduced. The method combines space-based high-resolution vertical aerosol profiles and SO₂ measurements the first 2 weeks after an eruption with air mass trajectory analyses. The SO₂ is located at higher altitude than in most previous studies. The detailed resolution of the SO₂ profile is unprecedented compared to other methods.
