Measuring and Modelling Volcanic Gas Releases to Earth's Atmosphere

该项目将继续研究向大气排放火山气体的问题。它将涉及使用各种技术对火山进行现场采样，对物种形成和反应进行热化学模拟，以及开发和使用遥感方法。在接下来的两年里，该计划将重点放在测试一种新的野外激光拉曼光谱仪上，该光谱仪有可能为遥感许多气体物种提供新的能力。想要火山/大气交换数据的大气科学家、对预测火山事件或火山气体灾害感兴趣的火山学家以及对高温下流体/岩石相互作用的金属挥发性和矿藏感兴趣的地球化学家可能会对这一结果感兴趣。

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.
