LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Sevilleta LTER collected on 1989-07-14

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Sevilleta LTER, originally collected on 1989-07-14 (17:12:48.6100500Z) by Landsat 4, row 37, path 33. Cloud cover was 10 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.

本数据集为塞维利亚特长期生态研究（Long-Term Ecological Research, LTER）区域的遥感空间栅格数据集，包含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, ETM+）影像数据。该数据由陆地卫星4号（Landsat 4）于1989年7月14日17时12分48.6100500秒（协调世界时）采集，轨道行号为37、轨道路径号为33，云量占比为10%。LEDAPS软件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，其功能为基于陆地卫星专题制图仪（Landsat Thematic Mapper, TM）及增强型专题制图仪Plus（ETM+）的一级数字量化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算法生成陆地卫星地表反射率气候数据记录。数据来源信息：美国国家航空航天局陆地卫星项目，2009年；数据标识：Landsat TM LT40330371989195XXX02，处理版本：LPGS_12.0.2；分发机构：美国地质调查局苏福尔斯分部，发布时间：2012年8月10日18时24分16秒（协调世界时）。
