1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: "Nadeau, Tricia A" <pnadeau@xxxxxxxx> Dear colleagues, We would like to make you aware of a new data publication containing all traverse-based SO2 emission rate measurements made by the Hawaiian Volcano Observatory from 2018 through 2022: Nadeau, P.A., Kern, C., Cappos, M.J., Elias, T., Warren, S.M., Lerner, A.H., Sealing, C.R., Slagle, C.L., Moisseeva, N., Holland, L.D., Clor, L., and Werner, C.A., 2023.

Emission rates (in t/d) during the published time period span five orders of magnitude through a range of activity styles unprecedented in recent times, including caldera collapse, the first prolonged non-eruptive period at KÄ«lauea since the early 1980s, a summit water lake, and the first eruption of Mauna Loa in nearly 40 years.
