Research Initiation Awards provide support for junior and mid-career faculty at Historically Black Colleges and Universities who are building new research programs or redirecting and rebuilding existing research programs. It is expected that the award helps to further the faculty member's research capability and effectiveness, improves research and teaching at his home institution, and involves undergraduate students in research experiences. The award to North Carolina Central University has potential broader impact in a number of areas. The goal of the project is develop a new Aerosol Optical Depth (AOD) retrieval approach that addresses outstanding challenges of remote sensing applications to air particulate matter (PM2.5). Particles less than 2.5 micrometers in diameter (PM2.5), which are generated by all types of combustion activities and certain industrial processes, are referred to as "fine" particles and are believed to pose a great health risks. Because of their small size, fine particles can lodge deeply into the lungs. This project will also enhance the research experience and training of undergraduate students at North Carolina Central University. The goal of this project is to develop a new methodology for retrieving Aerosol Optical Depth at a 1 kilometer resolution suitable for the aerosol microphysical environments and land surface types in North Carolina. This project seeks to allow better characterization of spatial and temporal variations in spectral Aerosol Optical Depth and thus improve the understanding of aerosol optical properties including estimation of the single scattering albedo and the asymmetry parameter. The specific objectives are to investigate the spectral characteristics of aerosols in urban areas; to develop a regression model to estimate PM2.5 using ground AOD measurements; and to develop a new method to retrieve AOD from satellite data at a 1 kilometer resolution.

研究启动奖为历史悠久的黑人学院和大学的初级和中级教师提供了支持，他们正在构建新的研究计划，或重新指导和重建现有的研究计划。预计该奖项有助于进一步促进教职员工的研究能力和有效性，改善他的家庭机构的研究和教学，并让本科生参与研究经验。 北卡罗来纳州中央大学的奖项在许多领域都具有更广泛的影响。该项目的目的是开发一种新的气溶胶光学深度（AOD）检索方法，该方法解决了遥感应用程序对空气颗粒物质的出色挑战（PM2.5）。直径小于2.5微米（PM2.5）的颗粒是由所有类型的燃烧活动和某些工业过程产生的，被称为“细”颗粒，被认为带来很大的健康风险。由于它们的尺寸很小，因此细颗粒可以深入肺部。该项目还将增强北卡罗来纳州中央大学的本科生的研究经验和培训。 该项目的目的是开发一种新的方法，用于以1公里的分辨率检索气溶胶光学深度，适合北卡罗来纳州的气溶胶微物理环境和地表类型。该项目旨在更好地对光谱气溶胶光学深度的空间和时间变化进行更好的表征，从而提高对气溶胶光学特性的理解，包括对单个散射反照率和不对称参数的估计。具体目标是研究城市地区气溶胶的光谱特征；开发回归模型以使用地面AOD测量值估算PM2.5；并开发一种新方法以1公里的分辨率从卫星数据中检索AOD。
