LEDAPS corrected Landsat Enhanced Thematic Mapper image data for North Temperate Lakes LTER collected on 1992-04-17

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for North Temperate Lakes LTER, originally collected on 1992-04-17 (16:10:13.3520750Z) by Landsat 5, row 028, path 025. Cloud cover was 40 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，包含针对北温带湖泊LTER站点的、经陆地卫星生态扰动自适应处理系统（Landsat Ecosystem Disturbance Adaptive Processing System, LEDAPS）校正的陆地卫星增强型专题制图仪影像数据。该数据由陆地卫星5号于1992年4月17日16时10分13.3520750秒（协调世界时）采集，轨道行号为028、路径号为025，云量覆盖率为40%。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，其功能为基于陆地卫星专题制图仪及增强型专题制图仪Plus的一级数字数值，计算大气层顶部反射率，并通过大气校正生成地表反射率产品。美国地质调查局（U.S. Geological Survey, USGS）已采用该LEDAPS算法，用于生成陆地卫星地表反射率气候数据记录。本数据相关来源标注如下：美国国家航空航天局陆地卫星计划，2009年；陆地卫星专题制图仪（Landsat TM）数据编号LT50250281992108XXX02，处理版本为LPGS_12.1.2；美国地质调查局苏福尔斯分部，2012年11月1日09时56分25秒（协调世界时）。
