Sentinel-2 .SAFE Archive Sample (Level1C and Level2A)

This data repository contains two Sentinel-2 scenes in the .SAFE (Standard Archive Format for Europe) archive structure made available by the European Space Agency (ESA). The data is used as a demonstrator to show the structure of .SAFE archives and how to handle them.

The repository contains Sentinel-2 data in two processing levels: The S2A_MSIL2A_*.SAFE dataset contains a scene that was corrected for atmospheric effects (i.e., surface reflectance values, Level-2A). The S2A_MSIL1C*.SAFE datasets in contrast, contains Sentinel-2 data at top-of-atmosphere level (i.e., Level-1C).

本数据集仓库包含两份由欧洲空间局（European Space Agency, ESA）发布的、采用.SAFE（欧洲标准归档格式，Standard Archive Format for Europe）归档结构的哨兵二号（Sentinel-2）影像场景。该数据集用作演示示例，用于展示.SAFE归档的结构及其处理方式。
本仓库包含两个处理级别的哨兵二号数据：S2A_MSIL2A_*.SAFE数据集对应的影像场景已完成大气校正，即搭载地表反射率数据的二级产品（Level-2A）；与之相对，S2A_MSIL1C*.SAFE数据集则包含大气层顶级别的哨兵二号数据，即一级产品（Level-1C）。
