Near-Real-Time Satellite Estimates of Surface PM2.5 Concentrations in Africa
In many parts of the world, air quality planning and management capabilities are limited by a lack of timely air quality observations. This is often the case in locations where ambient air quality conditions are worst. Globally, poor air quality is estimated to lead to 4.5 million premature deaths annually due to ambient exposure to PM2.5, and yet available data on air pollution remains scant or non-existent for many locations, including much of Africa. This approach provides timely data that is critically needed to fill that data gap, enhance air quality management, and improve health.
