I looked up Sentinel-3 satellite imagery for cross-validation. ESA also runs the Sentinel-3. While Sentinel-2 is essentially just a single high-res multispectral optical payload (MSI), Sentinel-3 packs a whole suite of sensors; optical (OLCI), precision thermal radiometry (SLSTR), and radar altimetry (SRAL). The spatial resolution gets chopped hard versus Sentinel-2 and the swath is huge, but it's more than sharp enough to flag severe thermal anomalies across open desert scrub. Breaking down the frames. OLCI is the familiar optical sensor. Pulled the OLCI L1B baseline imagery and ran the Highlight Optimized Natural Color processing layer to keep the blown out white pixels from clipping over high-albedo terrain. Then you have SLSTR L1B—provides the baseline thermal infrared and optical observations. It is used to verify sea/land surface radiant temperatures and active fire pixels. I selected the F1 Brightness Temperature layer, a dedicated mid-wave/thermal infrared band designed specifically for active fires (such as wildfires and gas flares). The delta between yesterday's pass and today is night and day. Again: zero interest in feeding the toxic bull/bear crossfire. Just sharing OSINT observations through open source feeds. #oott #iran
