Uman in Yucatán reflects the flat Yucatan Peninsula's suburban Mérida metropolitan corridor adjacent to the state capital, with vehicle traffic on surrounding roads and the henequen, services, and residential character contributing local sources. Consistent Caribbean and Gulf of Mexico trade winds provide background ventilation, while the flat karst plain allows reasonable dispersal and Uman generally maintains moderate Yucatan metropolitan suburban readings throughout most of the year.

When is air pollution at its worst in Uman?
Uman usually sees its poorest air quality when road traffic coincides with periods when maritime winds die down. Sea breezes typically keep conditions in check, except during still weather. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Uman 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.
