+# DeepExtremeCubes-video: Sentinel-2 Minicubes in Video Format for Compound-Extreme Analysis
+
+## Description
+
+### Dataset
+
+**DeepExtremeCubes-video** is a storage-efficient, analysis-ready re-packaging of the original [DeepExtremeCubes](https://doi.org/10.5281/zenodo.1234567) collection.
+All 42 k Sentinel-2 minicubes (2.56 km × 2.56 km, 2016-2022, 7 bands, 5-daily cadence) have been transcoded with **[xarrayvideo](https://github.com/IPL-UV/xarrayvideo)** into H.265/HEVC videos, achieving \~12 × lossless-perceptual compression (≈ 270 GB vs 2.3 TB) at ≈ 56 dB PSNR.
+
+This compact representation removes the prime bottleneck for training deep-learning models on spatio-temporal Earth-observation data, while preserving scientific fidelity for tasks such as:
+
+* **Impact mapping** of compound heat-wave & drought (CHD) events
+* **Forecasting** vegetation stress during extremes with ConvLSTM / U-TAE models
+* **Self-supervised pre-training** on long reflectance sequences
+
+### Sensors used
+
+* **Sentinel-2 MSI (Level-2A surface reflectance)** – Bands B02, B03, B04, B05, B06, B07, B8A at 10 m & 20 m (upsampled)
+* **ERA5-Land single-pixel time-series** (temperature, soil moisture, etc.)
+* **Copernicus DEM 30 m** (static)
+* **Cloud/SCL masks** from EarthNet Cloud-Mask v1
+
+> **Note:** All dynamic variables (bands, masks, ERA5-Land) are encoded as multi-channel videos; static rasters (DEM, land-cover) remain as compressed GeoTIFFs.
