GONZALEZ-CRUZ, M.B.; PIRE-RIVAS, S.F.  and  LOPEZ-JIMENEZ, P.A.. Sensitivity of conservative pollutants estimation using ISCST3 to input parameters for a case of study. Rev. Mex. Ing. Quím [online]. 2012, vol.11, n.2, pp.287-298. ISSN 1665-2738.

This paper describes a process of analysis of the Gaussian model ISCST3 of air pollutants dispersión applied in a densely populated area, the Higher Polytechnic Institute José Antonio Echeverría (CUJAE) in Havana. For the numerical simulation was carried out a sources and emissions inventory of air pollutants in the área, to estímate the concentration of the conservative pollutant, in this case sulfur dioxide. The objective is to show the sensitivity of numerical simulation with variation in the input of several parameters: average albedo, Bowen ratio, surface roughness and wind speed. After obtaining the results, the influence of variatíons in these parameters input and contaminant concentration studied is analyzed. Concluding that the wind speed is the parameter to which the model is more sensitive and has the lowest sensitivity to changes in albedo input. The least affected receptor concentration values estimated for 24 hours is the number 2, located in the center of the screen and land in the campus CUJAE. While for hourly values, receptors 1 and 3 are less sensitive.

Keywords : parameters; sensitivity analysis; Gaussian model; ISCST3; conservative pollutants; atmosphere contamination; sulfur dioxide.
