LEDAPS corrected Landsat Enhanced Thematic Mapper image data for California Current Ecosystem LTER collected on 1991-05-10

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for California Current Ecosystem LTER, originally collected on 1991-05-10 (17:44:55.0560880Z) by Landsat 5, row 037, path 040. Cloud cover was 30 percent. The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) software was originally developed by the National Aeronautics and Space Administration–Goddard Space Flight Center and the University of Maryland to produce top-of-atmosphere reflectance from Landsat Thematic Mapper and Enhanced Thematic Mapper Plus Level 1 digital numbers and to apply atmospheric corrections to generate a surface-reflectance product. The U.S. Geological Survey (USGS) has adopted the LEDAPS algorithm for producing the Landsat Surface Reflectance Climate Data Record.

本数据集为加州洋流生态系统长期生态研究（Long Term Ecological Research, LTER）站点的遥感空间栅格数据集，由经过LEDAPS校正的Landsat增强型专题制图仪影像数据组成。该数据由Landsat 5卫星于1991年5月10日17时44分55.0560880秒（协调世界时）采集，轨道行号037、路径号040，云量覆盖率为30%。Landsat生态系统扰动自适应处理系统（Landsat Ecosystem Disturbance Adaptive Processing System, LEDAPS）最初由美国国家航空航天局戈达德太空飞行中心与马里兰大学联合开发，可基于Landsat专题制图仪（Thematic Mapper, TM）及增强型专题制图仪Plus（Enhanced Thematic Mapper Plus, ETM+）的一级数字量化值计算大气顶部反射率，并通过大气校正生成地表反射率产品。美国地质调查局（United States Geological Survey, USGS）已采用该LEDAPS算法，用于生成Landsat地表反射率气候数据记录。美国国家航空航天局Landsat项目组，2009年，Landsat TM LT50400371991130XXX03，LPGS_12.1.3，美国地质调查局苏福尔斯分部，2012年12月8日20时12分33秒（协调世界时）。
