LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Harvard Forest LTER collected on 1989-10-14

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Harvard Forest LTER, originally collected on 1989-10-14 (14:58:05.2410310Z) by Landsat 5, row 30, path 13. 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Landsat生态扰动自适应处理系统（Landsat Ecosystem Disturbance Adaptive Processing System, LEDAPS）校正后的哈佛森林LTER站点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1989年10月14日14时58分05.2410310秒（协调世界时）采集，轨道行号为30、轨道路径号为13，云量占比20%。

Landsat生态扰动自适应处理系统（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，用于基于Landsat专题制图仪（Thematic Mapper, TM）及增强型专题制图仪Plus（Enhanced Thematic Mapper Plus, ETM+）的L1级数字数值计算大气顶反射率，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）已采用该LEDAPS算法生成Landsat地表反射率气候数据记录。
