About ChemTracker

ChemTracker is a real-time flight tracking application that predicts whether aircraft overhead are producing visible contrails. Developed by CCC Impact BV (Netherlands), ChemTracker uses live ADS-B flight data from a global receiver network, atmospheric conditions from 8 pressure levels via Open-Meteo, and the Schmidt-Appleman thermodynamic criterion to analyze every aircraft within 250 kilometers of the user's position. The app runs Monte Carlo simulations (25–50 evaluations per aircraft) and factors in solar visibility to determine if contrails are visible from the ground. ChemTracker is available worldwide as a progressive web app with a 14-day free trial.

What Makes ChemTracker Unique

  • Only app that predicts contrail formation using atmospheric science — powered by the Schmidt-Appleman thermodynamic criterion, the same model used in peer-reviewed aviation research.
  • Real-time scoring for every aircraft — each flight is classified as CLEAR, DISPERSING, or SPRAYING based on live atmospheric data and Monte Carlo simulation.
  • Sky Scanner — point your phone at a trail in the sky to instantly identify the aircraft responsible.
  • Solar visibility engine — factors in time of day and sun position for ground-level sighting prediction, so you only see trails that are actually visible right now.
  • Community field reports — users photograph and log trails to build a crowdsourced observation dataset that improves detection accuracy over time.

How It Works

  1. 1Live flight positions from a global ADS-B receiver network provide real-time location, altitude, and identity for every aircraft within 250 km.
  2. 2Atmospheric analysis retrieves temperature, humidity, and pressure at 8 altitude levels from Open-Meteo, matching conditions to each aircraft's flight level.
  3. 3Schmidt-Appleman scoring + Monte Carlo simulation runs 25–50 evaluations per aircraft, accounting for measurement uncertainty, to produce a contrail prediction with confidence level.

Short Description (150 characters)

Real-time flight tracking and contrail detection. See which aircraft are leaving trails above you. Powered by atmospheric science.

Long Description (500 characters)

ChemTracker shows you every aircraft in your area and predicts which ones are producing visible contrails. Using live ADS-B flight data, atmospheric conditions at 8 pressure levels, and the Schmidt-Appleman thermodynamic criterion, it runs Monte Carlo simulations to score each aircraft as CLEAR, DISPERSING, or SPRAYING. Point your phone at a trail in the sky to identify the plane. Track flights within 250 km, log sightings with photos, and explore community reports. Available worldwide with a 14-day free trial. No credit card required.
