Measuring and Modelling Volcanic Gas Releases to Earth's Atmosphere

点击翻译按钮获取中文摘要

This project is to continue work on volcanic gas emissions to the atmosphere. It will involve field sampling at volcanoes using a variety of techniques, thermochemical modelling of speciation and reactions, and development and use of remote sensing methods. In the next two years, the plan is to focus on the testing of a new field laser Raman spectrometer which has the potential of providing a new capability for remotely sensing many gas species. The results are of potential interest to atmospheric scientists who want data on volcano/atmosphere interchanges, volcanologists interested in forecasting volcanic events or in volcanic gas hazards, and geochemists interested in metal volatilities and ore deposits of fluid/rock interactions at high temperatures.
