SMAPVEX08 In Situ Vegetation Data, Version 1

This data set includes in situ vegetation data collected during the Soil Moisture Active Passive Validation Experiment 2008 (SMAPVEX08) campaign. Sampling was designed to coincide with satellite overpasses, such as Landsat's Thematic Mapper (TM) 5 and the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on NASA's Terra satellite (MODIS/Terra), which can be then used to estimate vegetation water content on the regional scale.

本数据集涵盖2008年土壤湿度主动被动验证实验（Soil Moisture Active Passive Validation Experiment 2008，缩写SMAPVEX08）野外考察期间采集的原位植被数据（in situ vegetation data）。本次采样的设计目标为与指定卫星的过境时间保持同步，涉及的传感器包括陆地卫星5号的专题制图仪（Landsat Thematic Mapper 5，缩写TM 5），以及搭载于美国国家航空航天局（National Aeronautics and Space Administration，缩写NASA）泰拉卫星的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，缩写MODIS，即MODIS/Terra）。利用该数据集可实现区域尺度的植被含水量（vegetation water content）估算。
