Passive Detection of Gases in the Atmosphere. Case Study: Remote Sensing of SO(2) in the UV Using LINUS
Abstract
An imaging UV spectrometer was used to study sulfuric plumes at Lassen Volcanic National Park, in an effort to identify and quantify SO 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 la laboratory measurements of SO(2) subsequently run at NPS. These data, along with additional measurements of platinum discharges for wavelength calibration, allow for comparison with atmospheric modeling calculations. Observations were modeled with the standard MODTRAN code. Comparisons between stimulated and measured data showed minor indications of SO(2) in the Lassen data. The gas concentration was estimated to be less than 10ppmv.
