AST-0421087 -- McGraw, University of New MexicoA compact, rugged, eye safe, low-cost lidar will be developed, specifically to measure atmospheric extinction at the New Mexico sky survey site at McDonald Observatory in West Texas to support the scientific programs of the CCD/Transit Instrument (CTI). The observing program of the CTI will accomplish a precise time-domain imaging photometric survey in multiple optical and near-infrared bandpasses of approximately 1% of the sky per night. The lidar data will enable more precise photometry by providing real-time measurements of the amount of atmopsheric extinction as well as its cause, i.e. low-lying aerosols, dust or smoke in the free troposphere, or high cirrus.

AST-0421087 -- McGraw，新墨西哥大学将开发一种紧凑、坚固、人眼安全、低成本的激光雷达，专门用于测量位于西德克萨斯州麦克唐纳天文台的新墨西哥州天空调查点的大气消光，以支持CCD/过境仪器（CTI）的科学计划。CTI的观测计划将在每晚约1%的天空中完成多个光学和近红外带通的精确时域成像光度测量。激光雷达数据将通过提供对大气消光量及其原因（即自由对流层中的低洼气溶胶、灰尘或烟雾或高卷云）的实时测量，实现更精确的测光。
