- **use cases**: ["Near-real-time tropical forest disturbance detection independent of cloud cover","Supply chain deforestation monitoring (palm, cocoa, rubber, soy)","Enforcement triggering for protected-area management agencies","Carbon project additionality and reversal monitoring"]
- **practical limitations**: ["Sentinel-1 fleet changed in 2022 (S-1B retired) and 2024 (S-1C added); revisit cadence and accuracy figures published in Reiche et al. 2021 reflect the S-1A+S-1B era and have not been re-validated post-fleet change in tier 1 sources accessed","Minimum mapping unit is 0.2 hectare (20 Sentinel-1 pixels); smaller disturbances are not detected","Coverage is humid tropical forest; not designed for boreal or temperate biomes"]
- **known artefacts**: ["Speckle noise inherent to single-look SAR; algorithm applies pixel-specific Gaussian Mixture Models and Bayesian confirmation to suppress false positives","Country count expansion from initial 6 (Congo Basin, 2021 launch) to a wider set across the humid tropics; exact current country count not confirmed from a tier 1 source in this pass"]
- **last verified date**: "2026-05-18T00:00:00.000Z"
