Ozone modeling in an ethanol, gasoline and diesel fuels environment: The metropolitan area of Sao Paulo, Brazil
- Univ. of Sao Paulo (Brazil)
- California Institute of Technology, Pasadena, CA (United States)
Over the past several years, in the Metropolitan Area of Sao Paulo (MASP), ambient ozone concentrations have reached over five times the concentration considered protective of public health by the World Health Organization, with routine occurrence of levels that exceed Brazil`s 1 hour National Ambient Air Quality Standard (160 {mu}g/m{sup 3}). For the past 19 years, ethanol has been used both as fuel (E95) and as gasoline additive (E20G80) in light duty vehicles. This talk will discuss the results of the application of the CIT photochemical airshed model to the February 16-17, 1989 meteorological experiment carried out in the MASP. Simulated hourly ozone concentrations for the 1989 vehicular fleet included three cases: (1) the actual fleet (F.95, E20G80, and diesels), (2) a light duty fleet fueled with E95 only, and (3) entirely with gasoline.
