Adaptive Thresholding (AT) For Snowmelt Detection With Calibrated Enhanced-Resolution Brightness Temperatures (CETB) - Timing And Regional Patterns For Case Study Of Alaska
--
https://doi.org/10.1016/j.srs.2026.100390 <-- shared paper
--
“HIGHLIGHTS:
• Data-driven Adaptive Thresholding (AT) for snowmelt detection using PMW CETB data.
• AT improves melt detection accuracy to ≤ 1.0 day MAE over legacy methods in Alaska.
• AT captures spatial and regional melt variability linked to snow class and terrain.
• AT is sensor-agnostic, scalable across frequencies and polarizations for broad use..."

“When it comes to water, the world is changing faster than ever. 🌏 Now you can map it just as quickly within QGIS. Seen [in the first figure] are examples from France and the Dominican Republic, which leverage 11 years of the Landsat-Sentinel Harmonized 30-meter product, to reveal temporal river dynamics, ephemeral rivers beneath a bay, and lake terraces…”
