ChemTracker

ChemTracker processes live data from aircraft transponders and atmospheric models to identify and visualise chemical or contrail trails produced by flights overhead. The system analyses flight paths in real time, applying atmospheric science calculations to distinguish visible spray or exhaust patterns from normal weather phenomena. Results are displayed on an interactive map that highlights the aircraft responsible for each detected trail within the user’s geographic area.

The tool is aimed at researchers, hobbyists, and community groups interested in monitoring aerial emissions and their potential environmental impact. By correlating flight telemetry with atmospheric conditions, it offers a transparent view of where and when aircraft are generating observable trails.

Implemented as an experimental utility, ChemTracker focuses on real‑time processing and map‑based visualisation, allowing users to observe and record trail activity without requiring specialized hardware or external data sources.
