Transparent documentation of where our data comes from. All sources are publicly accessible, scientifically validated, and independently verifiable.
This app relies on publicly available data from government agencies, scientific institutions, and community-driven projects. We don't generate our own flight or weather data—we aggregate and present information that anyone can access and verify.
All sources listed below are free to access (or have free tiers) and are used by researchers, meteorologists, and aviation professionals worldwide.
Real-time aircraft tracking using ADS-B (Automatic Dependent Surveillance-Broadcast) receivers worldwide. Provides flight number, aircraft type, altitude, speed, and heading.
Community-driven air traffic surveillance network. Academic research platform with historical flight data and open API access.
Commercial flight tracking service combining ADS-B, radar, and airline data. Provides detailed flight information and schedules.
National Oceanic and Atmospheric Administration. Provides upper-air observations, atmospheric soundings, and weather forecasts including temperature and humidity at flight levels.
European Centre for Medium-Range Weather Forecasts. Global numerical weather prediction models with high-resolution atmospheric data.
National Centers for Environmental Prediction. Provides GFS (Global Forecast System) model data including upper-level temperature and humidity.
Twice-daily atmospheric soundings from weather balloons launched worldwide. Direct measurements of temperature, humidity, and wind at all altitudes.
Interactive interface for browsing satellite imagery from NASA's Earth Observing System. Includes visible and infrared imagery showing contrails and clouds.
Geostationary Operational Environmental Satellites. High-resolution imagery updated every 5-15 minutes, useful for observing contrail formation and evolution.
Moderate Resolution Imaging Spectroradiometer. Twice-daily global coverage with specialized channels for detecting thin cirrus and contrails.
Educational resources and research findings from NASA's contrail studies. Includes lesson plans, scientific explanations, and historical context.
German Aerospace Center research on contrails and aviation's atmospheric impact. Leading institution in contrail cirrus research.
Educational website explaining contrail science with historical evidence, scientific references, and myth debunking. Excellent resource for understanding common misconceptions.
Academic journals publishing contrail research: Journal of the Atmospheric Sciences, Atmospheric Chemistry and Physics, Journal of Geophysical Research.
Combines real-time flight data (ADS-B Exchange, OpenSky) with atmospheric data (NOAA, ECMWF) to identify aircraft and explain contrail formation conditions.
Uses temperature and humidity data from weather models and radiosondes to explain why specific contrails persist or dissipate.
Learning modules are based on peer-reviewed research from NASA, DLR, and academic journals. All claims are scientifically sourced.
We encourage skepticism and independent verification. Every data source listed above is publicly accessible. You can:
