# Dataset Card for Copernicus-Pretrain |
|
|
|
|
|
<!-- Provide a quick summary of the dataset. --> |
|
|
|
|
|
[Copernicus-Pretrain](https://github.com/zhu-xlab/Copernicus-FM/tree/main) is a large-scale EO pretraining dataset with 18.7M aligned images covering all major Sentinel missions (S1,2,3,5P). |
|
|
|
|
|
*Officially named **Copernicus-Pretrain**, also referred to as SSL4EO-S ("S" means Sentinel), as an extension of [SSL4EO-S12](https://github.com/zhu-xlab/SSL4EO-S12) to the whole Sentinel series.* |

## Dataset Details |
|
|
|
|
|
<!-- Provide a longer summary of what this dataset is. --> |
|
|
|
|
|
Copernicus-Pretrain contains 18.7M aligned imagery from all major Sentinel missions in operation (Sentinel-1 SAR, Sentinel-2 multispectral reflectance, Sentinel-3 multispectral radiance, and Sentinel-5P atmospheric variables), as well as an elevation product Copernicus DEM GLO-30. |
|
|
The images are organized into ~310K regional grids (0.25°x0.25°, consistent with ERA5), densely covering the whole land surface and near-land ocean with eight distinct Sentinel modalities. |
