SEN12MS-CR-TS

The SEN12MS-CR-TS dataset contains time series of corresponding Sentinel-1 dual-pol SAR data as well as cloudy and cloud-free Sentinel-2 multi-spectral images. The patches are distributed across the land masses of the Earth, providing a global sample distribution. The time points of the samples are evenly spaced throughout the entire year, covering all meteorological seasons. This is reflected by the dataset structure. All patches are pro-vided in the form of 16-bit GeoTiffs containing the following specific information: - Sentinel-1 SAR: 2 channels corresponding to sigma nought backscatter values in dB scale for VV and VH polarization. - Sentinel-2 multi-Spectral: 13 channels cor-responding to the 13 spectral bands (B1, B2, B3, B4, B5, B6, B7, B8, B8a, B9, B10, B11, B12).

SEN12MS-CR-TS 数据集包含时序配对的哨兵1号（Sentinel-1）双极化合成孔径雷达（SAR）数据，以及含云、无云的哨兵2号（Sentinel-2）多光谱影像。所有影像块均分布于全球陆地范围，具备全域采样分布特征。样本的时间节点在全年内均匀分布，覆盖所有气象季节，该特性可通过数据集结构得以体现。所有影像块均采用16位GeoTIFF格式存储，包含以下特定信息：
- 哨兵1号（Sentinel-1）合成孔径雷达（SAR）数据：包含2个通道，分别对应VV、VH极化模式下dB尺度的σ⁰（后向散射系数）数值。
- 哨兵2号（Sentinel-2）多光谱数据：包含13个通道，对应13个光谱波段（B1、B2、B3、B4、B5、B6、B7、B8、B8a、B9、B10、B11、B12）。
