SGER: Validation of Forest Fire Smoke Plume Heights from the MISR Satellite Instrument Using Low-Cost, Hand-Held Video Recorders

这一探索性项目的重点是改进大气传输模型中森林火灾烟羽的表示。美国航天局TERRA卫星上的多角度成像分光辐射仪（MISR）仪器提供的烟羽高度数据可用于评价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成像。这一努力是一种新的、低成本的卫星数据验证方法，也是第一次努力从地面观测数据中建立森林火灾烟羽高度数据库，了解森林火灾污染物的迁移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务局之间的合作。农村地区的人民历来是得不到充分服务的群体，他们将成为这一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。

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.
