VAMOS Ocean-Cloud-Atmosphere-Land Study (VOCALS) Regional Experiment Scientific Program Overview

这是一个奖项，以支持继续规划人声-雷克斯。这不是NSF为该油田项目提供资金的承诺。这一筹资决定将通过进一步审查来确定。美洲季风系统(VAMOS)海洋-云-大气-陆地研究-区域实验(VOALS-REX)的可变性是一项国际实地实验，旨在更好地了解对东南太平洋(SEP)区域气候系统至关重要的物理和化学过程。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，人们对此知之甚少。Voals-Rex将重点研究安第斯山脉以西的云、气溶胶、海洋边界层(MBL)过程、上层海洋动力学和热力学、沿岸流和上升流、大规模下沉和区域日间环流之间的相互作用。野外试验最终是因为需要改进SEP以及更广泛的热带和亚热带地区的耦合气候系统的模式模拟。通过声乐观测和建模工作的协调将导致气候和区域预报机构更好地理解和预测。在声乐-霸王龙期间，将从几个平台获得多学科密集的观测数据集，包括飞机、科考船和地面陆地站点。这些数据集将被用来检验一套协调的假设，这些假设分为两大主题：(1)更好地理解海洋边界层(MBL)中的气溶胶-云-毛毛雨相互作用以及气溶胶的物理化学和时空特性；(2)更好地理解上层海洋、陆地和大气之间的化学和物理耦合。密集观测期为一个月，将在2008年10月进行，因为这是SEP上平流层积云覆盖最大、东南信风最强、上层海洋和低层大气耦合最紧密的月份。更广泛的影响：实地和随后的分析阶段将涉及并促进相当大的国际合作，并为一些科学家和研究生提供重要培训。实地生成的数据集将刺激各种数值过程模式的发展，并提供宝贵的制约条件，加速改进区域和全球气候模式。

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.
