In GEE
Load Sentinel‑2 from 2024-09-01 to “now”. Compute NDVI. Classify forest (1) vs. shrubland (2). Calculate simple fire potential = 1 − NDVI. Export a multi-band TIFF (RGB + classification + fire potential). Locally
Load the exported TIFF with rasterio. Load your Sentinel‑3 brightness temperature TIFF. Threshold the SLSTR data at 50 °C → temp_mask. Identify high fire-potential areas from the classification → high_fire_potential_mask. Combine: hot_and_high_fire_risk = temp_mask & high_fire_potential_mask. Visualize in geemap (or QGIS, etc.).
