LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Niwot Ridge LTER collected on 1992-08-22

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Niwot Ridge LTER, originally collected on 1992-08-22 (17:05:55.4130130Z) by Landsat 5, row 032, path 034. Cloud cover was 50 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.

本长期生态研究（Long Term Ecological Research，LTER）遥感空间栅格数据集，包含针对尼沃特岭LTER站点的、经LEDAPS校正的Landsat增强型专题制图仪（Enhanced Thematic Mapper，ETM+）影像数据。该影像由Landsat 5卫星于1992年8月22日17时05分55.4130130秒（协调世界时，UTC）采集，轨道行号为032，轨道路径号为034，云量覆盖率为50%。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研发，其功能为基于Landsat专题制图仪（Thematic Mapper，TM）及增强型专题制图仪Plus（ETM+）的一级产品数字号生成大气层顶反射率，并通过大气校正生成地表反射率产品。美国地质调查局（U.S. Geological Survey，USGS）已采用LEDAPS算法用于生产Landsat地表反射率气候数据记录。本数据源自美国国家航空航天局Landsat计划，2009年发布的Landsat TM影像LT50340321992235XXX02，处理版本为LPGS_12.1.2，由美国地质调查局苏福尔斯分部于2012年11月1日11时52分58秒（协调世界时）提供。
