This is project is a contribution to the VOCALS (VAMOS Ocean-Cloud-Atmosphere Study) project; VAMOS is the Variability of the American Monsoon System project.It is widely recognized that the marine atmospheric boundary layer and the stratus and stratocumulus clouds that top it are critically important for the verisimilitude of coupled climate models in the Southeastern Pacific. Most models, however, still have serious deficiencies in representing these features in this region. As part of the overall modeling efforts for VOCALS, in-situ observations from the VOCALS field campaign (VOCALS REx - VOCALS Regional Experiment), will be combined with previous field observations, and satellite data from CloudSat, CALIPSO, ICESat, and MODIS, to address the poor simulation of the marine boundary layer in the Southeast Pacific. In-situ and satellite data will be integrated to document and to understand the temporal and spatial variations of the marine boundary layer height and cloudsBroader impacts of this project are in its contributions to the overall VOCALS effort: the combined dataset will be made readily available through the investigators' web page and through CD/DVD dissemination. Results from the research will be presented to students in the lead investigator's gradate course.

这个项目是对VOCALS （VAMOS海洋-云-大气研究）项目的贡献；VAMOS是美国季风系统变率项目。人们普遍认为，海洋大气边界层及其上的平流层和层积云对东南太平洋耦合气候模式的真实性至关重要。然而，大多数模型在该区域表现这些特征方面仍然存在严重缺陷。作为VOCALS整体建模工作的一部分，VOCALS野外活动（VOCALS REx - VOCALS区域实验）的现场观测结果将与以前的野外观测结果以及来自CloudSat、CALIPSO、ICESat和MODIS的卫星数据相结合，以解决东南太平洋海洋边界层模拟的不足。将整合现场和卫星数据，以记录和了解海洋边界层高度和云层的时空变化。该项目的更广泛影响在于它对VOCALS整体工作的贡献：合并后的数据集将通过调查人员的网页和CD/DVD传播随时提供。研究结果将在首席研究员的研究生课程中呈现给学生。
