Sulfur dioxide emission rates - Kīlauea summit - past year

Sulfur dioxide emission rates - Kīlauea summit - past year

Detailed Description

Sulfur dioxide (SO2) emission rates measured using an upward-looking ultraviolet spectrometer. These data are collected by traversing the gas plume in a vehicle, downwind of Halema‘uma‘u, generally within and south of Kīlauea Caldera. Results from multiple traverses during a day are averaged to yield the emission rates shown here. Successful measurements depend on wind, weather, and staff availability. Values are preliminary and are subject to revision.
