Detecting volcanic sulfur dioxide plumes in the Northern Hemisphere using the Brewer spectrophotometers, other networks, and satellite observations

Christos S. Zerefos et al.

Data sets

SO2 columns World Ozone and Ultraviolet Radiation Data Centre

SO2 columns NOAA-EPA Brewer Spectrophotometer UV and Ozone Network

OMI and GOME-2 satellite SO2 data products Aura Validation Data Center

Surface SO2 concentrations over Europe European Environment Agency databases

Short summary
The paper makes a convincing case that the Brewer network is capable of detecting enhanced SO2 columns, as observed, e.g., after volcanic eruptions. For this reason, large volcanic eruptions of the past decade have been used to detect and forecast SO2 plumes of volcanic origin using the Brewer and other ground-based networks, aided by satellite, trajectory analysis calculations and modelling.
