The focus of this exploratory project is on improving the representation of smoke plumes from forest fires in atmospheric transport models. Smoke plume height data from the Multiangle Imaging Spectro-Radiometer (MISR) instrument aboard NASA's TERRA satellite can be used to evaluate the accuracy of smoke plume rise models as well as to estimate the extent to which forest fire smoke plumes penetrate the planetary boundary layer. In this project, ground-based plume height data will be derived from imaging obtained by U.S. Forest Service personnel using small, rugged, video recorders. This effort represents a novel, low-cost approach to satellite data validation, and a first effort at producing a database of forest fire smoke plume heights from ground-based observations.Understanding the transport of pollutants from forest fires is critical to assessing the impact of natural processes on air quality in the United States. This project establishes collaborations between universities and the Forest Service. People in rural areas, a traditionally underserved group, will be integral participants in this project. The results of this project will be a resource for the atmospheric research community and air quality regulatory agencies.

这个探索性项目的重点是改善大气运输模型中森林火灾烟雾的表现。来自美国宇航局TERRA卫星上的多角度成像光谱辐射计（MISR）的烟羽高度数据可用于评估烟羽上升模型的准确性，以及估计森林火灾烟羽穿透行星边界层的程度。在这个项目中，地面羽流高度数据将来自美国林务局人员使用小型、坚固的录像机获得的图像。这项工作代表了一种新颖的、低成本的卫星数据验证方法，也是首次通过地面观测建立森林火灾烟羽高度数据库。了解森林火灾中污染物的运输对于评估自然过程对美国空气质量的影响至关重要。该项目建立了大学和林业局之间的合作关系。农村地区是一个传统上得不到充分服务的群体，他们将成为这个项目不可或缺的参与者。该项目的成果将成为大气研究界和空气质量管理机构的资源。
