Develop an app or platform to crowd-source information for comparing changes in environmental factors, such as temperature, relative humidity, air pollution, with occurrence of symptoms of allergies and respiratory diseases. Create tools for public entry and grading of symptoms, including but not limited to cough, shortness of breath, wheezing, sneezing, nasal obstruction, itchy eyes; and geographic mapping of symptom frequency and intensity. Create a platform for comparison of symptom map with NASA provided data, with visualization options for web and/or smart phone.


Ventus is a web app that aims to study the effects of air pollution and climate changes on our health. This is achieved by crowd-sourcing symptom data from users worldwide, retrieving data about air quality and climate changes from public sources like OpenWeather and NASA GIBS, and combining the two datasets to deduce the relationships between air pollution and climate change, with the spreading of a certain disease.


  • View symptom map, combined with weather data
  • Get precautions and warnings about selected places for travel

Future Development

  • Integrate machine learning to automatically build the relationships between air quality and climate change, and diseases.
  • Add personalized results based on each user's medical history and symptom reports.
