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 situation, the emission sources, the dispersion of pollutants or the chemical reactions in the atmosphere. The result is the local […]

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) and Al Jubail (Saudi Arabia). All these cities have something in common, as they are all affected by three determining […]

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 the atmosphere, created by the wind blowing on arid and desert surfaces. The size of these particles found in natural […]

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 “island heat effect”, that usually occurs in big cities. Temperatures in these areas are higher than the surroundings, due to […]

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.

Meteosim is participating in the CASAP 2017

Meteosim presents an air quality technical paper during the CASAP 2017 event, celebrated in Cali, Colombia

The Colombian Congress and International Conference on Air Quality and Public Health – CASAP – is the most important meeting in Colombia addressing research and advances in air pollution issues and their impact on human health.

The 6th Edition of the Colombian Congress and International Air Quality and Public Heath Conference - CASAP 2017 will be held in the city of Cali, Colombia, from September 6th to 8th. This International event will be organized by Universidad del Valle, and is the second time that Meteosim is present with technical content.

Meteosim's team will present a technical lecture defining an standard methodology for obtaining an optimal configuration of the WRF model intended for air quality operative forecastings. This presentation will be the second day (September 7th) at 5:00pm in the Auditorio 3, at the venue of the event.
