项目摘要

1613067GroppiThis award, made in response to a EArly-Concept Grants for Exploratory Research (EAGER) proposal submission, provides funds to allow for the acquisition of key electronic components necessary to develop a proof-of-concept microwave radar system ultimately intended to study volcano plumes. The so-called WAMS (Water and Ash MM-Wave Spectrometer), would be a two-antenna, active-passive system. The low frequency system would function as a water vapor radiometer, using the 22 GHz emission line, while the high frequency system would estimate water vapor temperature (via radiometry at 183 and 232 GHZ), and also function as a radar to study the ash. The investigators at Arizona State University have experience in the design and construction of similar instruments for radio astronomy. A successfully developed WAMS instrument with a dual antenna active-passive radar capability for imaging volcanic plumes offers the potential to measure path-integrated water vapor in a volcanic plume concurrently with measurement of ash concentration in near real time and thus might contribute to fundamental advances in our knowledge of basic volcanic conduit processes leading to eruption. This support will allow for development of a prototype instrument that will be laboratory tested by an ASU graduate student. The potential of a realized WAMS instrument to yield a better understanding of volcanic ash plume dynamics and evolution (e.g., particle aggregation dynamics and transport) may have benefits for mitigating air traffic hazards from volcanic activity. Coupled with the student training in electronics testing that will be fostered by this award, these two aspects support NSFs mission of promoting the progress of science and advancing the national welfare.*** Broader ImpactsThe EAGER project would directly engage a graduate student in laboratory testing of the prototype WAMS instrument. The potential of WAMS for better understanding volcanic ash plume dynamics and evolution (e.g. particle aggregation dynamics and transport) may have benefits for mitigating air traffic hazards from volcanic activity.
1613067 Groppi该奖项是为了响应早期探索研究概念赠款(EAGER)提案提交而颁发的,提供资金用于采购开发概念验证微波雷达系统所需的关键电子元件,最终用于研究火山羽流。所谓的WAMS(水和灰毫米波光谱仪),将是一个双天线,有源-无源系统。低频系统将用作水蒸气辐射计,使用22 GHz发射线,而高频系统将估计水蒸气温度(通过183和232 GHz的辐射测量),并用作研究火山灰的雷达。 亚利桑那州立大学的研究人员在射电天文学的类似仪器的设计和建造方面有经验。一个成功开发的WAMS仪器与双天线有源无源雷达成像火山羽流的能力提供了潜在的测量路径集成的水蒸气在火山羽流同时测量灰浓度在近真实的时间,从而可能有助于我们的基本火山管道过程导致喷发的知识的根本进步。 这种支持将允许开发一个原型仪器,将由亚利桑那州立大学的研究生进行实验室测试。 实现WAMS仪器的潜力,以更好地了解火山灰羽流动力学和演变(例如,颗粒聚集动力学和运输)可能有利于减轻火山活动造成的空中交通危险。 再加上该奖项将促进电子测试的学生培训,这两个方面支持NSF促进科学进步和促进国家福利的使命。更广泛的影响EAGER项目将直接让一名研究生参与WAMS仪器原型的实验室测试。 WAMS在更好地了解火山灰羽流动力学和演变(例如颗粒聚集动力学和运输)方面的潜力可能有利于减轻火山活动对空中交通的危害。
