LAZO, Pamela; CURE, Michel y GAETE, Hernán. MODELING OF THE SULFUR DIOXIDE DISPERSION IN THE PUCHUNCAVI CITY USING THE PROGRAM ISC3. Ingeniare. Rev. chil. ing. [online]. 2006, vol.14, n.3, pp.229-237. ISSN 0718-3305. http://dx.doi.org/10.4067/S0718-33052006000200006.
The present work evaluates the atmospheric dispersion model ISC3 in Puchuncaví, Chile, modelling the emissions of SO 2 coming from the five stations that make up the air quality network in the industrial complex of Ventanas. 24 hour average concentrations for the years 2003 and 2004 were modelled, systematic errors being diminished by using a Kalman filter. The performance of the model is evaluated using a series of statistic tools. An analysis of the sensitivity of the SO 2 rate of emission, speed and wind direction variation is made, noting that the model is sensible to these factors, being this one of the causes of the errors found in four of the five stations that measured the quality of the air. It is concluded that the Kalman filter improves model ISC3, providing results with fewer errors in the five air quality measuring stations.
