The CALPUFF and AERMOD atmospheric pollutant dispersion models simulate the physical and chemical conditions that affect the dispersion of different atmospheric pollutants.

Impact of covid-19 on air quality in Catalonia
During the lockdown and the subsequent de-escalation phases established by the Spanish Government, mobility and work activity were significantly reduced, consequently impacting the levels of anthropogenic emissions into the atmosphere.
Low Emission Zones
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 significant health risks that exist today.
Mitigation measures in mining environments
Particulate matter is the main pollution problem in mines. The mining area is constantly exposed to a lot of activities that generate a large amount of dust and suspended particles.
The emissions model
Nowadays, we are able to forecast the levels of contamination in a region by using the air quality (AQ) models.
Sand storms, megacities and intense industrial activity
Según la Organización Mundial de la Salud (OMS) las ciudades más contaminadas del mundo son Zabol (Irán), Gwalior (India), Allahabad (India), Riyadh (Arabia Saudí) y Al Jubail (Arabia Saudí).
Dust: when pollution comes from deserts
When we talk about natural dust, we are referring to a mixture of solid particles suspended in the atmosphere, created by the action of wind on arid or desert surfaces.
Heat island: air quality impacts
Asphalt, buildings or the nonexistence of green spaces are the main cause of the island heat effect, that usually occurs in big cities.
New air quality paper published by Meteosim
Meteosim, in collaboration with the Polytechnic University of Catalonia (UPC) and the University of Las Palmas de Gran Canaria (ULPGC), published an interesting article in which it analyses and evaluates the coupling between a photochemical model and a model of finite elements of application on air quality. This study was previously presented at the prestigious HARMO congress in its 2017 edition.
