El Yunque peak (elevation 1067 m) at the eastern end of Puerto Rico is frequently in clouds, so that cloud water and aerosols can be conveniently sampled from a ground-based platform, avoiding the cost and complexities of airborne sampling. The orographic nature of these clouds enables the establishment of empirical relations between the composition of pre-cloud and after-cloud aerosols and the composition of the cloud water, and therefore offers a potential for a better understanding of cloud chemistry. Sampling and chemical analyses of aerosols and cloud water at El Yunque constitute the main component of the proposed research. At the El Yunque site, cloud water, interstitial aerosols, and total (cloud + interstitial) aerosols will be collected. Cloud water and water-soluble aerosols will also be analyzed for anions and cations. Filter samples will be analyzed for trace elements, total carbon, and black carbon.

埃尔云克峰（海拔1067米），位于 波多黎各经常有云，所以云水和 气溶胶可以方便地从地面采样， 平台，避免了机载的成本和复杂性， 取样. 这些云的地形特性使得 建立经验关系的组成 云前和云后气溶胶及其组成 云水，因此提供了一个更好的 了解云化学。 取样和化学品 在埃尔云克的气溶胶和云水分析构成了 这是拟议研究的主要内容。 关于El Yunque 站点、云水、间隙气溶胶和总量（云+ 间隙）气溶胶。 云水和 还将分析水溶性气溶胶中的阴离子， 阳离子。 将对过滤器样本进行微量元素分析， 总碳和黑碳。
