"Breathe, breathe in the air. Don't be afraid to care."
Breathe is a modern, open-source iOS application designed to monitor real-time air quality data across the Jammu, Kashmir and Ladakh region. Built using Swift and SwiftUI, Breathe offers a fluid, expressive interface adhering to native iOS design standards.
Why Breathe?
Breathe provides localized air quality data by combining crowdsourced and open ground sensors with satellite modeling. Our goal is to offer accurate environmental data for the JK & Ladakh region in an open-source and transparent manner.
Data Sources & Methodology
Breathe aggregates data from multiple independent, publicly available sources:
Local Sensors: For AirGradient Enabled Zones, Breathe utilizes crowdsourced ground sensors from AirGradient (https://www.airgradient.com/) to provide real-time PM2.5 and PM10 readings.
Environmental Models: For other pollutant concentrations and the remaining districts/Non AirGradient Enabled Zones, Breathe integrates data from Open-Meteo (https://open-meteo.com/), an open-data meteorological provider.
Calculations: AQI values are calculated based on established US-EPA and Indian National AQI (NAQI) standards.
