The objective of this study is to determine the mechanism responsible for the formation and perpetuation of large and conspicuous rifts and gradients often visible in satellite observations of otherwise uniform stratus and stratocumulus cloud decks. A fully instrumented Twin Otter aircraft operated by the Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) will measure cloud and aerosol properties in and around the cloud-free regions. The data will be analyzed with the purpose of producing a physical model of the marine boundary layer that explains the formation and longevity of the rifts. Flights will be conducted from Monterey, California. Results of the study will be valuable for modeling aerosol and warm cloud processes, understanding the radiative properties of maritime clouds, and for interpretation of satellite data. The project is supported as a collaboration between Dr. Jonsson and Dr. Philip Durkee (Co-PI) and Dr. Bruce Albrecht at the University of Miami.

本研究的目的是确定机制，负责形成和永久性的大而明显的裂缝和梯度通常可见的卫星观测，否则均匀的层云和层积云甲板。 由跨学科遥控飞机研究中心（CIRPAS）运营的全仪表双水獭飞机将测量无云区域及其周围的云和气溶胶特性。 将对这些数据进行分析，目的是制作海洋边界层的物理模型，解释裂缝的形成和寿命。 航班将从加州的蒙特雷起飞。 这项研究的结果对于模拟气溶胶和暖云过程、了解海洋云的辐射特性以及对卫星数据的解释将是有价值的。 该项目是由Jonsson博士和Philip Durkee博士（Co-PI）以及迈阿密大学的布鲁斯阿尔布雷希特博士合作支持的。
