Short summary

Sulfuric acid (H₂SO₄) is commonly accepted as a key precursor for atmospheric new particle formation. However, direct measurements of [H₂SO₄] remain challenging, motivating the development of proxies. Using data collected in two different volcanic plumes, we show, under these specific conditions, the good performance of a proxy from the literature and also highlight the benefit of the newly developed proxies for the prediction of the highest [H₂SO₄] values.
