Asmara's air quality benefits from its exceptional Eritrean Highland position at 2,325 metres — one of Africa's highest capitals — with consistent northeast monsoon and highland breezes providing reliable natural ventilation. Vehicle traffic on surrounding roads and the government, manufacturing, and services corridor contribute modest local sources, while the extraordinary elevated highland position above most regional pollution sources and the outstanding Eritrean plateau climate generally maintain Asmara among Africa's more moderately ventilated highland capital environments throughout most of the year.

Are air quality levels in Asmara based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
