This report documents the SO2 emission rates for the period 2014-2017, from the summit and East Rift Zone eruptions of Kīlauea, along with the wind or plume speed and direction data used to calculate the emission rates. The Kīlauea summit SO2 emission rates are reported every ten seconds, as measured by a novel configuration of 10 fixed, upward looking UV spectrometers (FLYSPEC array), and for days with at least 2 hours of data, the daily means are reported. The plume or wind speeds used to calculate the emission rates are measured by cross correlation of plume features (see William-Jones and others (2006)) or by ground-based anemometer (SDH) and are reported with the emission rates. When the SDH ground based wind...

Kīlauea Volcano on the Island of Hawai‘i was in a state of nearly continuous eruption from 1983 – 2018. Large amounts of sulfur dioxide gas (SO2) were released from the volcano’s East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit of the volcano from 2008-2018. This data release presents ground-based estimates of SO2 emission rates from the two gas emission sources for the period 2008-2013. For the two-year period 2008-2010, the summit data have been revised from previously published emission rates (Elias and Sutton, 2012). During this era, very high emissions from the volcano’s newly active lava lake led to opaque plumes and challenges in accurately quantifying SO2 column...
