      AirWare application: Porto do Acu, Brazil

      AirWare/EIA application for an industrial district       On-line Model System
      (sub-contracting to Braile Enghenaria Ltda.)

      Location: Coastal location North of de Janeiro.

      • UTM 24 - SW: 256.000/7.560.000, NE: 296.000/7.600.000
      • Master domain of 120km by 120km;
      • Main model domain 45km x45+km (plus sub-domains, including logistics corridor)
      • Major city: Campos (dos Goytacazes), ~ 430,000 inhabitants;
      • Sao Joao da Barra, North of of the study area, population was 28,609 (2005).

      Terms of Reference for the model applications:

      10 BASIC SCENARIOS: scenarios 9 and 10 combine the previous ones, run with AERMOD over periods of 30 month with (substance specific) aggregation periods: hourly, 8 hourly, 24 hourly, annual, calculated for each scenario, substance and x and aggregation period: basic statistics (max, average, number of exceedences, AOT) and a list of the 30 highest values, with reference to the

      Additional scenarios (Na, Nb, Nc, ...) have been introduced for sensitivity analysis, NO2 (AERMOD/OLM and CAMx) and traffic (TRAFFIC), specific emission groups (e.g., traffic) mass budget checks and source apportioning. More than 30 major model scenarios derived from subsets and combinations of the basic 10 (each up to three years, up to 6 substances, with variations of emissions, source geometry) totalling 239 annual model runs were performed and evaluated for a total of 359 emission sources.
