Sentinel-2 NDVI z-score cube
The complete example is maintained in the Sentinel-2 recipe. It loads observed red/NIR bands, derives NDVI, standardizes the selected time period and plots the result. Live STAC and asset access are required.
For direct index loading, use the vegetation-index noun. For raw bands, use surface reflectance; the NDVI loader is not a substitute for a raw-band loader.
