Evaluation of air quality through estimation and comparison of typical non parametric curves

Evaluation of air quality through estimation and comparison of typical non parametric curves

We estimate typical daily curves for the pollutants carbon monoxide, nitrogen dioxide and ozone in the years 2003, 2004 and 2005 in Cali city, by means of a nonparametric smoothing technique. The curves evolution is studied through statistical comparison using a nonparametric analysis of covariance, hoping to find out patterns and trends. The results show the existence of a statistically significant reduction in the typical pollution levels throughout the years. The data comes from the stations of the Air Quality Monitoring Network.

Se estiman curvas típicas diarias para los contaminantes monóxido de carbono, dióxido de nitrógeno y ozono en los años 2003, 2004 y 2005 en la ciudad de Cali, mediante una técnica no paramétrica de suavización. Se estudia la evolución de las curvas comparándolas estadísticamente por medio de un análisis de covarianza no paramétrico, con el fin de identificar patrones y tendencias. Los resultados muestran que existe una reducción estadísticamente significativa de los niveles típicos de contaminación a través de los años. La información utilizada proviene de las estaciones de la red de monitoreo de calidad del aire en la ciudad.
