LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Shortgrass Steppe collected on 1991-08-29

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Shortgrass Steppe, originally collected on 1991-08-29 (17:00:57.8100310Z) by Landsat 5, row 032, path 033. 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.

本长期生态研究（Long Term Ecological Research，LTER）遥感空间栅格数据集，包含针对短草草原（Shortgrass Steppe）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（Landsat Enhanced Thematic Mapper）影像数据。该数据由陆地卫星5号（Landsat 5）于1991年8月29日17时00分57.8100310秒（协调世界时UTC）采集，轨道行号032、轨道路径号033，云量覆盖率为30%。
LEDAPS最初由美国国家航空航天局戈达德航天飞行中心（National Aeronautics and Space Administration–Goddard Space Flight Center）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（Landsat Thematic Mapper，TM）及增强型专题制图仪Plus（Enhanced Thematic Mapper Plus，ETM+）的一级数字数值，计算大气层顶反射率，并通过大气校正生成地表反射率产品。
美国地质调查局（United States Geological Survey，USGS）已采用LEDAPS算法，用于生成陆地卫星地表反射率气候数据记录。
