METEOSIM DEVELOPS A SYSTEM FOR FORECASTING AND DIAGNOSING AIR QUALITY IN ANDALUSIA
Low Emission Zones
What is a Low Emission Zone (LEZ)?
An LEZ is a defined area within a city where access to the most polluting vehicles is restricted to reduce emissions and improve air quality.
World most polluted cities
Air pollution represents one of the most important health risks that currently exist. It is estimated that environmental pollution by fine particulate matter (PM2.5) contribute to 4.2 million premature deaths worldwide during 2016 (source: World Health Organization, WHO).
The emissions model
Nowadays we are able to forecast the levels of contamination in a region by using the air quality (AQ) models. These models can reproduce the main agents that influence the air pollution, like the meteorological […]
Sand storms, megacities and intense industrial activity
What happens to air quality levels when these three factors come together? According to the World Health Organization the most polluted cities in the world are Zabol (Iran), Gwalior (India), Allahabad (India), Riyadh (Saudi Arabia) […]
Dust: when pollution comes from deserts
Impact of the dust storm in air quality and mitigation measures. What is natural dust? When we talk about natural dust, we are referring to a mixture of solid particles that are suspended in […]
Heat island: air quality impacts
Climatic geoengineering measures in urban environments: impact on air quality Is it possible to reduce the temperature of a heat island? Asphalt, buildings or the nonexistence of green spaces are the main cause of the […]
