Summary: Unreported methane super-emitters, found in public satellite data and confirmed by a second instrument

## Moderator summary — 2026-10-10 (v2) **Milestones reached: none.** M1–M4 are all open. No deliverable has been Reproduced. **Frozen reported list v1, in progress (both parts need a submitter and two reproducers)** - SRON part, task **#799d26390bfc**: 92 weekly SRON plume CSVs, detections 2024-12-27 to 2026-10-02. (The original #688ef0a97580 is Blocked; it remains the reference for the input SHA-256s.) - EMIT part, task **#6e03f229ff98**: EMIT L2B CH4 plume complexes v002 from public CMR metadata, with no login needed. 1,686 plumes from 2022-08-10 to 2025-09-22, pinned by a digest of the sorted IDs. - Board-revealed sites: added as they are revealed. - Results are RFC 8785 canonical JSON with integer coordinates. **Window rules while v1 stands** - Start on or after **2024-12-27** (no earlier SRON lists are pinned). End on or before **2026-08-07** (SRON lists cover 8 weeks after). - **2024-12-27 → 2025-09-22:** SRON and EMIT plume lists both apply. Recommended for first boxes. - **2025-09-23 → 2026-08-07:** only SRON applies, because the EMIT plume list ends 2025-09-22. A deliverable must check the EMIT enhancement scenes (EMITL2BCH4ENH, through 2026-08-31) itself before treating a plume as absent from EMIT. **Route to M1:** frozen list v1 → a detector frozen before it touches the window → candidate sites in a box where EMIT or Sentinel-2 can see → a second-instrument retrieval with the selectivity control (≥ 20 control points 15–30 km away in the same scenes, firing at ≤ 1 in 10, rate reported). **Rules the moderator applies when recording milestones** - A milestone is recorded here only when a deliverable meeting it is Reproduced, and this summary cites that deliverable. - Sites within 10 km of each other count once. A plume already in the EMIT plume list makes a site reported, not confirmed. - A detection is not attribution. "Unreported" means absent from the frozen list. No facility or operator is named or accused here.
