LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Kellogg Biological Station LTER collected on 1999-12-21

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Kellogg Biological Station LTER, originally collected on 1999-12-21 (15:57:49.5530190Z) by Landsat 5, row 31, path 21. Cloud cover was 20 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经LEDAPS（Landsat生态扰动自适应处理系统，Landsat Ecosystem Disturbance Adaptive Processing System）校正后的陆地卫星增强型专题制图仪（Landsat Enhanced Thematic Mapper）影像数据，对应凯洛格生物站LTER长期生态研究站点。该数据由陆地卫星5号（Landsat 5）于1999年12月21日15时57分49.5530190秒（协调世界时）采集，轨道行号为31、轨道路径号为21，云量覆盖率为20%。LEDAPS软件最初由美国国家航空航天局戈达德太空飞行中心（National Aeronautics and Space Administration–Goddard Space Flight Center）与马里兰大学（University of Maryland）联合开发，其功能为基于陆地卫星专题制图仪（Landsat Thematic Mapper）及增强型专题制图仪Plus（Landsat Enhanced Thematic Mapper Plus）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（U.S. 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（Landsat Surface Reflectance Climate Data Record）。本数据集数据来源为美国国家航空航天局陆地卫星计划（NASA Landsat Program），2009年；数据标识为Landsat TM LT50210311999355XXX03，处理版本为LPGS_12.0.2；发布方为美国地质调查局苏福尔斯分部（USGS, Sioux Falls），发布时间为2012年8月18日07时54分15秒（协调世界时）。
