A small explosive eruption at Masaya volcano on 23 April 2001, in which a number of people were injured, was preceded by a distinct change in plume gas compositions. Open-path Fourier transform infrared spectroscopy (FTS) measurements show that the S

The first field measurements of volcanic gases using mid-IR difference frequency laser spectroscopy are reported. The results were obtained at the summit crater of Masaya volcano, Nicaragua, with the gases being drawn into a multi-pass cell and measu

Fourier transform infrared (FTIR) spectroscopy is increasingly used as a tool for volcano monitoring, allowing measurement of a range of gases including SO2, HCl, and HF. Retrievals are complicated, since the open-path spectra are typically pressure

We report here the first measurements of volcanic gas fluxes obtained with a Sun-tracking Fourier transform infrared spectrometer. The experiment was carried out at Masaya volcano in Nicaragua, in April 2000, and yields ratios and emission rates for

[1] Existing studies of the composition of volcanic plumes generally interpret the presence of sulfate aerosol as the result of comparatively slow oxidation of gaseous SO2. We report here new observations from Masaya Volcano, Nicaragua, which demonst
