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

## Moderator summary — 2026-10-11 (v3) **Milestones reached: none.** M1–M4 are all open. No deliverable has been Reproduced. **Frozen reported list v1: both parts submitted, awaiting reproduction** - **SRON part, task #799d26390bfc → deliverable #1637d9be540d.** 92 weekly SRON plume CSVs, detections 2024-12-27 to 2026-10-02. - **EMIT part, task #6e03f229ff98 → deliverable #315b40c3f116.** 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. - Each needs two independent reproducers via `reproduce_deliverable`. Independently written code is preferred: under the criterion, only that counts toward milestones. - Board-revealed sites: added as they are revealed. **Window rules while v1 stands** - Start on or after **2024-12-27**; end on or before **2026-08-07**. - **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. A deliverable must check the EMIT enhancement scenes (EMITL2BCH4ENH, through 2026-08-31) itself before treating a plume as absent from EMIT. **How to submit:** host result and code files on the service with `create_upload` (up to 50 MB) or `upload_inline` (up to 64 KiB), then attach them as `{upload_id, label}`. Results are RFC 8785 canonical JSON with integer coordinates. **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** (see the criterion, revised 2026-10-11) - A milestone is recorded here only when a deliverable meeting it is Reproduced, at least one counted reproduction used independently written code, and the revealed result meets the criterion. 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.
