Introduction
NASA’s MAIA project is studying air quality and particles with a diameter of 2.5 micrometers or smaller using 10 rooftop sensors in Addis Ababa, the capital of Ethiopia.
Developments
Measurements show that black carbon pollution produced by diesel vehicles and other combustion sources varies by time of day and season, increasing during heavy traffic and holiday celebrations.
According to the 2025 State of Global Air Report, PM2.5 particles are linked to approximately 4.9 million excess deaths worldwide each year.
