This is Sentinel-2 at 10-meter resolution, over the Colossus 1 parcel. LFM2.5-VL finds thirty-five near-identical rectangular units arranged in rows — the signature of a natural-gas turbine bank. Stateflow dates this scene to April 2026. The same parcel was empty fields 22 months earlier.
NO₂ is the fingerprint of combustion — gas turbines, diesel generators, anything that burns hydrocarbons in air. TROPOMI measures a tropospheric NO₂ column every single day, from 824 km up, over every square kilometre on Earth. Here's what it logged over Riverport Road.
Each lane is one site on a time axis. The hatched red regions are periods of documented operation with no matching permit. The green regions are permitted operation. Operational-start (OP) comes from the atmospheric onset date; permit-filed (PRM) is the date the state received the first application.
Independent instruments, different orbits, different chemistries — all pointing at the same parcel of land and the same six-month gap.
The satellite record establishes, independently of any filing, that 3231 Riverport Road began emitting nitrogen dioxide at volumes consistent with large gas-turbine operation on or around 21 October 2024.
The first permit application at this address was filed 184 days later, and covered fewer than half of the units the optical record can count.
Boxtown, the community immediately downwind, already carries a cancer-risk burden four times the national average. The regulatory process protected them six months slower than the ESA archive could have.
