Abstract

   The current problems in relation to odor pollution episodes make it necessary to have methods to assess odor impacts. Such assessment can be performed using dispersion models that allow to estimate odor concentrations considering the emissions, the meteorology and the topography, among other data. Pollutant dispersion modeling is usually based on minimum averaging times of one hour; however, some pollutants require shorter averaging times, as it is the case of odors. Recently, the Atmospheric Research Group of the Faculty of Engineering of Bilbao has set up a methodology to perform dispersion studies in the Cadagua valley area (near Bilbao), that could be used in other areas with similar characteristics. The GIA used the version 5.8 of the non-steady-state gaussian plume model CALPUFF (version officially approved by the EPA), which allows a maximum temporal resolution of one hour, coupled with the mesoscale model RAMS. There exists a later version (version 6), that has the capability of using sub-hourly temporal resolution. The aim of this study is to set up the methodology using version 6 of the CALPUFF system to perform dispersion simulations with high spatio-temporal resolution in areas of complex topography. The preliminary results show more and higher peaks of pollutant concentration using 10 minutes averaging times than those estimated with smaller temporal resolution. This could be important for an adequate estimation-interpretation of odor nuisance.
