embed2scale/SSL4EO-S12-downstream

SSL4EO-S12-downstream数据集是用于Embed2Scale挑战的数据集，包含Sentinel-1和Sentinel-2数据。该数据集由开发集5149个数据立方体和测试集8111个数据立方体组成，分别约为60GB和90GB。数据立方体包含两种极化方式（VV和VH）的S1数据和13个S2 L1C通道以及12个S2 L2A通道，每个位置在四个月份（3-5月、6-8月、9-11月、12-2月）进行采样。数据以zipped zarr文件格式存储，其结构为（位置数、时间戳数、通道数、高度、宽度）。该数据集结构与SSL4EOS12 v1.1数据集相同。

The SSL4EO-S12-downstream dataset is used for the Embed2Scale Challenge, containing Sentinel-1 and Sentinel-2 data. The dataset consists of a development set of 5149 datacubes and a test set of 8111 datacubes, approximately 60GB and 90GB in size, respectively. The data cubes include S1 data in two polarizations (VV and VH) and 13 S2 L1C channels as well as 12 S2 L2A channels, with each location sampled at four times during the months of March-May, June-August, September-November, and December-February. The data is stored in zipped zarr file format, structured as (number of locations, number of timestamps, number of channels, height, width). The structure of this dataset is identical to the SSL4EOS12 v1.1 dataset.
