AfriSAR: Canopy Cover and Vertical Profile Metrics Derived from LVIS, Gabon, 2016

This dataset includes footprint-level canopy structure products derived from data collected using NASA's Land, Vegetation, and Ice Sensor (LVIS) during flights over five forested sites in Gabon during February and March 2016. Three types of canopy structure information are included for each flight: 1) vertical profiles of canopy cover fraction in 1-meter bins, 2) vertical profiles of plant area index (PAI) in 1-meter bins, and 3) footprint summary data of total recorded energy, leaf area index, canopy cover fraction, and vertical foliage profiles in 10-meter bins. Canopy structure metrics are provided for each waveform (20-m footprint) collected by the LVIS instrument. These data were collected by NASA as part of the AfriSAR project. AfriSAR is a NASA collaboration with the European Space Agency (ESA), German Aerospace Center (DLR), and the Gabonese Space Agency (AGEOS) that is collecting data useful for deriving forest canopy structure and will help prepare for and calibrate current and upcoming spaceborne missions that aim to gauge the role of forests in Earth's carbon cycle.

本数据集包含源自于美国宇航局（NASA）陆地、植被和冰传感器（LVIS）在2016年2月至3月对加蓬五个森林地点飞行采集的数据所生成的树冠结构层级的结构产品。每个飞行任务中均包含三种类型的树冠结构信息：1）树冠覆盖率在1米间隔的垂直剖面；2）植物面积指数（PAI）在1米间隔的垂直剖面；3）足迹汇总数据，包括总记录能量、叶面积指数、树冠覆盖率和10米间隔的垂直叶层剖面。LVIS仪器收集的每个波形（20米足迹）均提供了树冠结构指标。这些数据作为AfriSAR项目的一部分由NASA收集。AfriSAR是美国宇航局与欧洲空间局（ESA）、德国航空航天中心（DLR）和加蓬航天局（AGEOS）的合作项目，旨在收集有助于推断森林树冠结构的数据，并将有助于为当前和即将进行的旨在评估森林在地球碳循环中作用的航天器任务进行准备和校准。
