This Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) data set was developed from Landsat 5 Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data for use in studying land cover features during the Soil Moisture Experiment 2004 (SMEX04).

数据用户须知：本数据集的文档仅由首席研究员（Principal Investigator）提供，未由NSIDC进一步完善、全面审核或编辑，因此本数据集的技术支持可能有限。

本归一化植被指数（Normalized Difference Vegetation Index, NDVI）与归一化水体指数（Normalized Difference Water Index, NDWI）数据集，基于陆地卫星5号专题制图仪（Landsat 5 Thematic Mapper, TM）及增强型专题制图仪（Enhanced Thematic Mapper Plus, ETM+）数据构建，用于2004年土壤湿度实验（Soil Moisture Experiment 2004, SMEX04）期间的地表覆盖特征研究。
