Assessment of the Mt. Pinatubo Eruption and Effects on Polar Ozone

该项目由小额赠款资助， 探索性研究（SGER）计划，将跟踪发展， 平流层气溶胶云的传输， 山脉皮纳图博火山爆发。 测量将在 在不同纬度的气球上探测， 到达极地地区（约1年）。 测量 将确定云的分布，并测量它们的 垂直剖面以及组成部分的大小和形状 粒子 特别重要的是， 云被困在（或排除）下一个极地冬季 漩涡，因为它是已知的平流层气溶胶发挥作用， 在破坏极地臭氧层方面发挥了重要作用。 特别 将注意到半球的差异。 该项目由极地项目部联合资助 和大气科学部。

This project, which is supported under the Small Grant for Exploratory Research (SGER) program, will trace the development and transport of the stratospheric aerosol clouds that were injected by the Mt. Pinatubo volcanic eruptions. The measurements will be made by balloon borne sondes at various latitudes until the cloud reaches polar regions (approximately 1 year). The measurements will determine the distribution of the clouds and measure their vertical profiles as well as the size and shape of the constituent particles. Of particular importance will be to what extent the cloud is trapped within (or excluded from) the next polar winter vortices, since it is known that stratospheric aerosols play an important role in the destruction of polar ozone. Particular attention will be paid to the hemispheric differences. This project is jointly funded by the Division of Polar Programs and Division of Atmospheric Sciences.
