Abstract
An imaging UV spectrometer was used to study sulfuric plumes at Lassen Volcanic National Park, in an effort to identify and quantify SOâ presence. The NPS instrument, LINUS (Lineate Imaging Near -Ultraviolet Spectrometer) was taken to Lassen on September 13 and 14, 2002. Data taken there are compared to laboratory measurements of SOâ subsequently run at NPS. These data, along with additional measurements of platinum discharges for wavelength calibrat ion, allow for comparison with atmospheric modeling calculations. Observations were modeled with the standard MODTRAN code. Comparisons between simulated and measured data showed minor indications of SOâ in the Lassen data. The gas concentration was estimated to be less than 10ppmv.
