Equation output

E_CH4 = A × EF × (1 − SF) × cycles
     = 4200 × 185 × (1 − 0.42) × 1.6
E_tCO2e = E_CH4 × GWP_CH4 / 1000
     ≈ 38,500 tCO2e / yr

Run engine

GCC-437 v1.2

Deterministic — same seed always produces the same point estimate. Seeded jitter stays within the ±14% uncertainty band.

Runs on-map in the GeoLibre workspace (Processing → Remote Sensing → NDWI). Inspectable and re-runnable.

Methodology-as-code, reproducible by design

The engine is versioned and deterministic. Any change bumps the version tag; historical results remain reproducible from sealed inputs and the recorded seed.
