New framework uses VSWIR imaging to map wildfire temperatures

Researchers have developed a new framework for analyzing wildfire temperatures using VSWIR imaging spectroscopy data from NASA's AVIRIS-3 instrument. This framework employs a full-physics approach with a forward model to resolve solar and emitted radiance, optimized for fast convergence on a graphics processing unit (GPU). The system achieved an RMSE of 41.8 Kelvin in simulated spectra and was applied to over 168 overflights during the 2025 FireSense campaign, demonstrating a residual radiance fit of less than 10%. The retrieved temperature parameters also showed good generalization to space-borne instruments like EMIT, with an absolute error of 30 K. AI

IMPACT This research could improve wildfire monitoring and response by providing more accurate real-time temperature data from satellite imagery.
