near-miss on one test · score 0.873 · Sentinel-2CPhysics checks
B12 dimmed 3.4% while visible bands barely changed (0.6%).
- B12 dimmed 3.4% (more than 1%)
- B11 changed 1.7%, as much as B12
- Visible and near-infrared changed 0.6%, under half of B12
- Plume lies 80° from the wind (more than 45°)
Emission rate
≈ 19.1 t/h
68% range 14.6–23.2 t/h
Screening-grade satellite estimate: confirm with a hyperspectral satellite, an OGI drone or a ground survey before enforcement or carbon crediting.

B12 dimmed 2.0%, but visible bands changed 2.2% too: a surface change, not methane.
- B12 dimmed 2.0% (more than 1%)
- B11 changed 0.3%, less than half of B12
- Visible and near-infrared changed 2.2%, more than half of B12
- Plume lies 30° from the wind (within 45°)
Emission rate
Rejected as methane: no emission rate is reported for surface change.
Emissions
No T1 event, so no annual estimate.
Screening-grade satellite estimate: confirm with a hyperspectral satellite, an OGI drone or a ground survey before enforcement or carbon crediting.
Detection and limits
Steady emission above 5 t/h is ruled out (95%).
Over dense Indian landfills a single pass catches about 25–35% of plumes of 10 t/h or more.
Control point: 0 flags in 73 passes · p vs control 0.238
Screening-grade satellite estimate: confirm with a hyperspectral satellite, an OGI drone or a ground survey before enforcement or carbon crediting.
