This RAPID project supports the deployment of a network of low-cost sensors on the Big Island of Hawaii to measure the production rate of sulfate aerosols during the current eruption of the Kīlauea volcano. Sulfate aerosols are of particular interest due to their role as an air pollutant at ground level that causes respiratory health effects and their role in the upper atmosphere as having a potential cooling impact on climate. A network of low-cost sensors at ground level around the Kīlauea volcano will measure the chemical conversion rates of primary gases, such as sulfur dioxide, to secondary air pollutants, such as sulfate aerosols, and assess how these rates vary under different atmospheric conditions (e.g., humidity, temperature, sunlight, cloudy vs. clear air). This research also will demonstrate the feasibility of using low-cost sensors as part of monitoring and emergency response efforts during extreme air quality events, such as wildfires. The uncertainty about the duration of the volcanic eruption at Kīlauea requires that this work be supported through a RAPID so that the research can be conducted while the eruption is ongoing. The results of this study will have implications for human health, air quality policy and emissions regulation, and climate.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个快速的项目支持在夏威夷大岛上部署低成本传感器网络，以衡量硫酸盐气溶胶的生产速率在当前的基洛瓦火山喷发期间。硫酸盐气溶胶特别引起了人们的关注，因为它们是地面水平的空气污染物的作用，从而引起呼吸健康效应及其在上层大气中的作用，因为它们对气候具有潜在的冷却影响。基地火山周围地面上低成本传感器的网络将测量主要气体的化学转化率，例如二氧化硫，例如硫酸盐气溶胶等二级空气污染物，并评估这些速率在不同的大气条件下如何变化（例如，湿度，温度，温度，云，云，云层清晰的空气）。这项研究还将证明在极端空气质量事件（例如野火）期间使用低成本传感器作为监测和应急工作的一部分的可行性。基洛伊亚火山喷发持续时间的不确定性要求通过快速支持这项工作，以便在爆发时可以进行研究。这项研究的结果将对人类健康，空气质量政策和排放法规和气候有影响。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准通过评估来支持的。
