This is an award to support continued planning for VOCALS-REx. It is not a commitment by NSF to fund the field project. That funding decision will be determined by means of further review. The Variability of the American Monsoon Systems (VAMOS) Ocean-Cloud-Atmosphere-Land Study - Regional Experiment (VOCALS-REx) is an international field experiment designed to better understand physical and chemical processes central to the climate system of the Southeast Pacific (SEP) region. The climate of the SEP region is a tightly coupled system involving poorly understood interactions between the ocean, the atmosphere, and the land. VOCALS-REx will focus on interactions between clouds, aerosols, marine boundary layer (MBL) processes, upper ocean dynamics and thermodynamics, coastal currents and upwelling, large-scale subsidence, and regional diurnal circulations, to the west of the Andes mountain range. The field experiment is ultimately driven by a need for improved model simulations of the coupled climate system in both the SEP and over the wider tropics and subtropics. The coordination through VOCALS of observational and modeling efforts will lead to improved understanding and predictions by climate and regional forecasting agencies.Multi-disciplinary intensive observational datasets will be obtained during VOCALS-REx from several platforms including aircraft, a research vessel, and a surface land site. These datasets will be used to test a coordinated set of hypotheses that are organized into two broad themes: (1) improved understanding of aerosol-cloud-drizzle interactions in the marine boundary layer (MBL) and the physicochemical and spatiotemporal properties of aerosols; (2) improved understanding of the chemical and physical couplings between the upper ocean, the land, and the atmosphere. The intensive observational period will be a month long and will take place during October 2008, chosen because it is the month during which the coverage of stratocumulus over the SEP is at its greatest, the southeast trade winds are at their strongest, and the coupling between the upper ocean and the lower atmosphere is at its tightest. Broader impacts: The field and subsequent analysis phases will involve and foster considerable international collaboration and provide important training for a number of scientists and graduate students. The datasets generated in the field will stimulate the development of a broad range of numerical process models, and provide invaluable constraints that will accelerate the improvement of regional and global climate models.

该奖项旨在支持VOCALS-REx的持续规划。这不是NSF资助实地项目的承诺。这一供资决定将通过进一步审查加以确定。美国季风系统变率（VAMOS）海洋-云-大气-陆地研究-区域实验（VOCALS-REx）是一项国际实地实验，旨在更好地了解东南太平洋（SEP）地区气候系统的物理和化学过程。SEP地区的气候是一个紧密耦合的系统，涉及海洋，大气和陆地之间的相互作用知之甚少。VOCALS-REx将侧重于安第斯山脉以西的云、气溶胶、海洋边界层过程、上层海洋动力学和热力学、沿岸流和上升流、大规模沉降和区域日环流之间的相互作用。实地实验最终是由需要改进的模式模拟耦合的气候系统在SEP和更广泛的热带和亚热带地区。通过VOCALS对观测和模拟工作进行协调，将提高气候和区域预报机构的理解和预测。VOCALS-REx期间将从包括飞机、研究船和地面站点在内的多个平台获得多学科密集观测数据集。这些数据集将用于测试一组协调的假设，这些假设分为两大主题：（1）提高对海洋边界层（MBL）中气溶胶-云-毛毛雨相互作用以及气溶胶的物理化学和时空特性的理解;（2）提高对上层海洋，陆地和大气之间化学和物理耦合的理解。密集的观测期将长达一个月，将在2008年10月期间进行，选择这一时期是因为SEP上空的层积云覆盖范围最大，东南信风最强，上层海洋和下层大气之间的耦合最紧密。 更广泛的影响：实地和随后的分析阶段将涉及并促进大量的国际合作，并为一些科学家和研究生提供重要的培训。该领域产生的数据集将促进开发范围广泛的数值过程模型，并提供宝贵的约束条件，加速改进区域和全球气候模型。
