Sentinel-2 reflectance data for testing the SpiPy implementation of the SPIRES algorithm.

This dataset contains georeferenced satellite observations over a snow-covered region, suitable for testing spectral unmixing algorithms and snow property retrieval. Contents:1. sentinel_r.nc (1.4 GB) - Sentinel-2 surface reflectance - Spatial dimensions: 921×1347 pixels - Spectral bands: 9 (B2-B7, B8A, B11, B12) - Temporal: 2 time steps 2. sentinel_r0.nc (705 MB) - Background (snow-free) reflectance - Same spatial/spectral dimensions - Used for spectral unmixing background endmember These files are used for integration testing and validation of the SpiPy package.
