Analysis of SO2 and Aerosols from 2018 Kilauea Volcanic Activity Using SO2 Sondes, AERONET, and Pandora Spectrometer Data
Abstract
With the surge in volcanic activity and the creation of new fissures in Kilauea's East Rift Zone in May 2018, emissions of SO2 increased significantly. Between June 21-30 nine SO2sondes with enhanced upper and lower detection limits were launched from the southern portion of the island, downwind from the volcanic fissures to provide vertical profiles of SO2. The sonde launches were collocated with in-situ and remote sensing measurements in a mobile lab to provide SO2 mixing ratios and SO2 columns. A suite of remote sensing instruments were placed downwind of the fissures in Naalehu to provide longer term measurements of SO2 columns, AOD, cloud and ash plume heights, complimenting measurements available in Hilo and Keaau, nominally upwind of the fissures. We present preliminary results from the SO2 sonde flights and continuing data streams from Hawaii.
