VGAM: Compact and Low Power Mass Spectrometer-based Instrumentation for Volcanic Gas Monitoring
<p>Compact mass spectrometers can provide simultaneous multi-species analysis with high sensitivity and precision.<br> For volcanic gas monitoring in situ, instrumental mass spectrometry requires reliability and ruggedness combined<br> with low power usage and portability. The Volcanic Gas Analytical Monitor (VGAM) is capable of quantitative<br> molecular analysis of a variety of atmospheric and volcanic gases in a single sensor by ion trap mass<br> spectrometry. These gases include: H 2 , He, H 2 O, N 2 , O 2 , Ar, NO, N 2 O, CO, CO 2 , H 2 S, SO, SO 2 , and CH 4 . Unlike<br> previous field instruments using magnetic sector and quadrupole mass spectrometers (MS) with vacuums backed<br> by compact turbomolecular pumps, the VGAM uses a low-power autoresonant ion trap MS and NEG-Ion vacuum<br> that operate at only 25 W total power, which is often the power requirement for just the mass spectrometer. Ratio-<br> metric mass spectral response is combined with total pressure measurements to report absolute partial<br> pressures. Data are generated in real time and are recorded to internal flash memory. Relatively low power (&lt;1<br> Watt) data telemetry to remote sites is possible. Analysis of volcanic plumes, fumaroles, and solfatara fields is<br> accomplished by direct inlet of gases, after trapping as much excess water vapor in both the external and internal<br> foreline as possible. We report herein on the VGAM auto-run and post-processing procedures, initial calibration<br> results for CO 2 , and the results of a brief field deployment at Sulphur Banks solfatara field, Kilauea Volcano,<br> Hawaii.</p>
Data for recreating figures of scientific paper by Hermanson et al on volcanic impacts on climate
<p>This data is the data necessary to recreate the figures that appear in a draft manuscript submitted to the AGU journal Journal of Geophysical Research - Atmospheres for peer review. When / if the manuscript is accepted then the article will be linked from here. The data is in netcdf files. The data was created by processing (mainly averaging) data from five different institutions. It was given to the authors for the purpose of scientific research only.</p>
