Satellite instruments have been providing measurements of global volcanic emissions of
sulfur dioxide (SO 2) since 1978, based on observations in the ultraviolet (UV), infrared (IR) …

The global flux of sulfur dioxide (SO2) emitted by passive volcanic degassing is a key
parameter that constrains the fluxes of other volcanic gases (including carbon dioxide, CO2) …

Sulfur dioxide (SO 2) measurements from the Ozone Monitoring Instrument (OMI) satellite
sensor processed with the new principal component analysis (PCA) algorithm were used to …

In June 2019 a stratospheric eruption occurred at Raikoke (48∘ N, 153∘ E). Satellite
observations show the injection of ash and SO 2 into the lower stratosphere and an early …

Over the last four decades, space-based nadir observations of sulfur dioxide (SO2) proved
to be a key data source for assessing the environmental impacts of volcanic emissions, for …

Recently, Whitburn et al.(2016) presented a neural-network-based algorithm for retrieving
atmospheric ammonia (NH 3) columns from Infrared Atmospheric Sounding Interferometer …

Sulphur dioxide (SO 2) fluxes of active degassing volcanoes are routinely measured with
ground-based equipment to characterize and monitor volcanic activity. SO 2 of unmonitored …

Besides their strong contribution to weather forecast improvement through data assimilation,
thermal infrared sounders onboard polar-orbiting platforms are now playing a key role for …

Despite their potential to slow global warming, until recently, the radiative forcing associated
with volcanic aerosols in the lowermost stratosphere (LMS) had not been considered. Here …

Retrievals of sulfur dioxide (SO2) from space‐based spectrometers are in a relatively early
stage of development. Factors such as interference between ozone and SO2 in the retrieval …
