A chemtrail is a term used by many observers to describe the persistent white trails left behind by aircraft in the sky. While officially classified as condensation trails (contrails) formed when hot jet exhaust meets cold atmospheric air, a growing community of concerned citizens questions whether all trails can be explained this simply. ChemTracker lets you investigate for yourself by showing you exactly which aircraft are leaving trails, at what altitude, and under what atmospheric conditions — so you can draw your own conclusions based on real data.

How does ChemTracker work?

ChemTracker combines real-time ADS-B flight data with atmospheric science to show you every aircraft in your area. It uses your location, live weather data including humidity and temperature at cruising altitude, and the known science of contrail formation to predict which planes are likely producing visible trails. You can point your phone at the sky and see overlaid flight information in real time.

Can I track chemtrails in real-time?

Yes. ChemTracker provides real-time tracking of all aircraft in your vicinity and highlights which ones are currently producing visible trails. Using live ADS-B transponder data and atmospheric readings, the app updates continuously so you can monitor exactly what is happening in the sky above your location at any moment. You can also set up alerts to be notified when trail-producing aircraft enter your area.

What is the difference between a chemtrail and a contrail?

A contrail (condensation trail) is the official explanation for the white lines left by aircraft — formed when water vapor in jet exhaust freezes in cold, humid air at high altitudes. The term chemtrail is used by researchers and observers who believe some trails may contain additional substances beyond normal water vapor, noting that some trails persist and spread for hours while others disappear quickly. ChemTracker helps you study these differences by showing atmospheric conditions, aircraft identity, altitude, and trail persistence predictions for every flight overhead.

Frequently Asked Questions

Are there chemtrails at Hollywood Burbank Airport today?

ChemTracker monitors real-time atmospheric conditions above Hollywood Burbank Airport (BUR) to predict contrail formation. Currently, 3 of 8 pressure levels show conditions favorable for contrail formation — indicating moderate likelihood of persistent trails above this airport.

Why do planes at Hollywood Burbank Airport leave trails?

Aircraft departing or overflying Hollywood Burbank Airport (BUR) produce contrails when hot, humid jet exhaust mixes with cold ambient air at cruising altitude. This forms ice crystals that become visible as white trails. Contrails persist when the surrounding air is supersaturated with respect to ice (RH-ice above 100%), which can cause them to spread into cirrus-like haze lasting hours.

How does ChemTracker monitor aircraft at Hollywood Burbank Airport?

ChemTracker uses live ADS-B transponder data to track every aircraft in the airspace around Hollywood Burbank Airport (BUR) in real time. Each aircraft's altitude is cross-referenced against atmospheric data from Open-Meteo at 8 pressure levels. The app shows flight numbers, current altitudes, and whether atmospheric conditions at each level are favorable for contrail formation.

What atmospheric conditions cause contrails at Hollywood Burbank Airport?

Contrails form above Burbank when air temperature drops below approximately −40°C at cruising altitude (typically 8,000–12,000 metres). The Schmidt-Appleman criterion calculates the precise threshold based on ambient pressure, relative humidity, and engine efficiency. When relative humidity with respect to ice exceeds 100%, contrails persist and spread. ChemTracker checks all 8 pressure levels above Hollywood Burbank Airport for these conditions every 30 minutes.
