🔥 ECCO Recycling Landfill Fire (Calgary): A View from Space 🛰️ Sentinel-2 (MSI) satellite imagery from September 9, 2026. Visualized using a 12-4-2 band combination (SWIR-2 – Red – Blue): 🔹 Thermal zone (~400 × 400 m): A bright red hotspot at the Recycling facility. The shortwave infrared band (B12, 2.19 µm) captures a strong thermal radiance response: open combustion hotspots, excavated smoldering waste layers, and fresh hot ash. Due to the high sensitivity of the SWIR band to high-temperature sources, even localized sub-pixel hotspots create a pronounced signal across the entire active landfill cell. 🔹 Smoke plume: Rendered as a semi-transparent bluish veil drifting east and southeast over residential and industrial areas. The blue band (B2) captures light scattering from smoke particulates and aerosols (PM2.5 / PM10), while the infrared SWIR band easily penetrates the haze, allowing the underlying infrastructure to remain clearly visible. #Sentinel2 #Copernicus #RemoteSensing #Calgary #YYC #AirQuality
