Volcanic ash is often neglected in climate simulations because ash particles are assumed to have a short atmospheric lifetime, and to not participate in sulfur chemistry. After the Mt. Kelut eruption in 2014, stratospheric ash-rich aerosols were observed for months. Here we show that the persistence of super-micron ash is consistent with a density near 0.5 g cm<sup>-3</sup>, close to pumice. Ash-rich particles dominate the volcanic cloud optical properties for the first 60 days. We also find tha ...[more]
