When a project submitted to the Environmental Impact Assessment System (SEIA) emits pollutants or precursors of pollutants into the atmosphere, air quality models are frequently used as a tool to evaluate the impact of these emissions on the air resource, and the consequent impact on other renewable natural resources and people’s health.
Due to the relevance of this resource, the Environmental Assessment System (SEA) established the “Guide for the use of Air Quality Models”, which presents clear criteria, good practices and the minimum information necessary for the assessment, so to advance in improving the environmental evaluation in Chile and to comply with the legal mandate established in Law No. 19,300.
This Guide provides information and guidelines on the most relevant aspects of photochemical modeling within environmental assessment, namely:
In this regard, this Guide recommends the Community Multi-scale Air Quality (CMAQ) model as a model to simulate atmospheric photochemistry in Chile, where our company has extensive experience in this important tool. For meteorological modeling, which is an input for these photochemical models, our company generates this information through the use of the Weather Research and Forecasting – Advanced Research WRF (WRF-ARW) model.
Our PARTICULAS professionals have more than 16 years of experience in photochemical modeling of atmospheric pollutants. We have carried out modeling of meteorological variables with the WRF model and photochemical modeling (CMAQ) in various areas of Chile and Peru.
We invite you to learn more about our personalized service carried out in Chile and Peru. Indeed, in Chile we have applied CMAQ in the smelter mining areas, Mejillones, the saturated or latent areas of the O’Higgins, Biobío, Araucanía and Los Lagos regions. For Peru we have used CMAQ for the cities of Trujillo, Huancayo, Chiclayo, Cusco, Piura and Iquitos (Study carried out for the OEFA).
