The goal of this project is to develop an instrument capable of long-term monitoring of volcanic emissions. Such an instrument could be deployed at strategic locations around an active volcanic site and left unattended for periods of up to six months to monitor important chemical and environmental parameters. The data would be stored in an internal computer and periodically transmitted to a remote observation station by telemetry. Unattended deployment of the instrument would greatly reduce the costs and logistical problems associated with repeated visits to remote sites and volcanologists with near-real-time data on chemical and physical parameters, this technology will be a valuable tool for validating models relating chemical emissions to volcanic activity. It could ultimately serve as an early warning system for pending eruptions. While this technology does not currently exist, the construction of such an instrument system is possible because of modern microelectronic capabilities coupled with recent advances in chemical sensor technology. This was demonstrated in Phase I of this project. The objectives of Phase II are the design, fabrication, optimization, and field testing of prototype analyzers. Following extensive environmental testing, the units will be deployed in the field.

该项目的目标是开发一种能够 长期监测火山喷发物。 这样一项文书 可以部署在活火山周围的战略要地 并在无人看管的情况下进行长达六个月的监测 重要的化学和环境参数。 这些数据将 存储在内部计算机中，并定期传输到 通过遥测技术建立的远程观测站。 无人值守部署 该文书的实施将大大降低成本和后勤费用， 与多次访问偏远地点有关的问题， 火山学家可以获得近实时的化学和物理数据 参数，这项技术将是一个宝贵的工具， 将化学排放与火山活动联系起来的模型。 它可以 最终成为即将爆发的早期预警系统。 虽然这项技术目前还不存在， 这样的仪器系统是可能的，因为现代 微电子能力加上最近的进展， 化学传感器技术 这一点在第一阶段的 这个项目 第二阶段的目标是设计， 原型的制造、优化和现场测试 分析仪。 经过广泛的环境测试， 将被部署到外地。
