title: Ground Based Ultraviolet Remote Sensing of Volcanic Gas Plumes.
abstract: Ultraviolet spectroscopy has been implemented for over thirty years to monitorvolcanic SO₂ emissions. These data have provided valuable information concerningunderground magmatic conditions, which have been of utility in eruption forecastingefforts. During the last decade the traditionally used correlation spectrometers have beenupgraded with miniature USB coupled UV spectrometers, opening a series of exciting newempirical possibilities for understanding volcanoes and their impacts upon the atmosphere.Here we review these technological developments, in addition to the scientific insightsthey have precipitated, covering the strengths and current limitations of this approach.
