NASA SNWG/OPERA Project

This dataset contains Level-3 Dynamic OPERA surface water extent product version 1. The data are validated surface water extent observations beginning April 2023. Known issues and caveats on usage are described under Documentation. The input dataset for generating each product is the Harmonized Landsat-8 and Sentinel-2A/B/C (HLS) product version 2.0. HLS products provide surface reflectance (SR) data from the Operational Land Imager (OLI) aboard the Landsat 8 satellite and the MultiSpectral Instrument (MSI) aboard the Sentinel-2A/B/C satellite. The surface water extent products are distributed ove...本数据集包含第3级动态OPERA地表水范围产品V1.0。该数据为2023年4月起的经验证地表水范围观测数据。数据集使用时的已知问题与注意事项详见文档章节。生成每份产品的输入数据集为Landsat-8与Sentinel-2A/B/C协同产品（Harmonized Landsat-8 and Sentinel-2A/B/C, HLS）V2.0。HLS产品提供搭载于陆地卫星8号的陆地成像仪（Operational Land Imager, OLI）以及搭载于Sentinel-2A/B/C卫星的多光谱仪器（MultiSpectral Instrument, MSI）所采集的地表反射率（Surface Reflectance, SR）数据。本地表水范围产品的分发范围为……
