Quantification of CO2 Flux by Volcanoes with GASPEC

这是一项进一步发展一种新仪器（GASPEC）的建议，作为一种真正的遥感器，能够定量测量火山的二氧化碳排放。原型仪器是在过去4年里开发出来的，其最终目标是测试火山爆发预测模型，并生产一种活火山监测工具。该项目的第一步将是利用亚利桑那州北部的一座燃煤电厂作为一个可接近的自然实验室。在这一步中，建议将GASPEC获得的复杂原始数据反卷积为代表火山附近大气真实情况的CO2、H2O蒸汽、云、灰、温度变化等引起的信号。第二步是将仪器带到埃特纳火山，因为这是一座非常著名的活火山，被认为是世界上火山二氧化碳的主要来源。在项目的这一阶段，重点将放在GASPEC和其他目前可用的远程和直接传感器获得的CO2/SO2变化的长期观察和比较上。计划中的研究将允许更友好地使用该仪器，并且应该能够消除低层大气中红外的复杂性，这可能使GASPEC成为火山的标准监测工具。

9614703 Williams This is a proposal to develop further a new instrument (GASPEC) as a true remote sensor capable of measuring quantitatively CO2 emissions from volcanoes. The prototype instrument was developed in the past 4 years and has as a final goal to test eruption forecasting models and produce a monitoring tool for active volcanoes. The first step for this project will be to use a coal-fired power plant in N. Arizona as an acessible natural laboratory. In this step, it is proposed to work on deconvoluting the complex raw numbers obtained by the GASPEC into signals caused by CO2, H2O vapor, clouds, ash, temperature changes, etc. which represent the reality of the atmosphere near volcanoes. The second step will be to take the instrument to Etna, as this is a very well-known active volcano, thought to be the major source of volcanic CO2 in the world. During this stage of the project, the focus will be on long-term observation and comparison of the changes in CO2/SO2 as obtained by GASPEC and other remote and direct sensors that are currently available. The planned research will allow a more friendly use of the instrument and should be capable of deconvoluting the complexity of infrared in the lower atmosphere, which may make the GASPEC a standard monitoring tool in volcanoes.
