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).

本数据存储库包含由欧洲航天局（ESA）提供的两个 Sentinel-2 场景文件，以 .SAFE（欧洲标准存档格式）存档结构进行存储。该数据集作为示范，用以展示 .SAFE 存档的结构及其处理方法。

存储库中包含了两个处理级别的 Sentinel-2 数据：S2A_MSIL2A_*.SAFE 数据集包含经过大气效应校正的场景（即地表反射率值，2A级），而与之相对的 S2A_MSIL1C*.SAFE 数据集则包含 Sentinel-2 的顶大气层数据（即1C级）。
