Any atmospheric particulate concentration exceeding 35 µg/m³ triggers automatic suspension of all cargo manifests. The metric is binary: launch or hold.
Q2364111: Air Quality Index definitionGround stations (Intracoastal), satellite telemetry (ISS), and predictive dispersion models converge on a single truth vector. No single source is authoritative; consensus is required.
ISS-071-E439719: Canadian plume capturePM2.5 particles remain airborne 7–10 days; PM10 settles in 3–5. The buffer window scales logarithmically with particle mass. Wildfire smoke (Q113488705) contains both classes.
Q113488705: Wildfire smoke compositionBase buffer: 14 days. Multiplier: 1.5× for each 50-point AQI increment above 100. Maximum buffer: 90 days (total planetary quarantine).
No human approval required. The system holds all manifests until three consecutive hourly readings confirm AQI<100. Resume sequence: critical supplies → crew rotation → commercial cargo.
