LI-RAMIREZ, Jade Alexandra; PEREZ-ZAPATA, Ángela María; DUQUE-MENDEZ, Néstor Darío  e  ARISTIZABAL-ZULUAGA, Beatriz Helena. Generation and representation of air quality indexes: a case study applied to Manizales. Iteckne [online]. 2016, vol.13, n.2, pp.174-184. ISSN 1692-1798.

Air quality indexes for Manizales domain were implemented and a data warehouse was structured, allowing to people to display and obtain indexes information for free. Two kinds of indexes were calculated: Air Quality Indexes (AQI) and Percentage of exceedance of normed Limits (PELN). Indexes for Sulfur dioxide (SO₂), Ozone (O₃) and Particulate matter (PM₁₀ and PM_2.5) were calculated and analyzed using R software and Openair library. Access to the data warehouse is possible from the virtual platform called Centro de Datos e Indicadores Ambientales de Caldas (CDIAC) in charge of storing, processing and providing to people the information from the system of air quality monitoring stations. Results exhibit low concentrations of analyzed pollutants, with AQI ranging from 10 to 60 for particulate matter and, from 0 to 27 for gases. Generally AQI remained at Good category and occasionally at Moderate category. The PELN of pollutants did not exceed 1%.
