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 modeling within the environmental assessment, namely:
In this regard, this Guide recommends the Calpuff and Aermod models as models to simulate the dispersion of particles and gases in Chile, where our company has extensive experience and has the Calpuff View and Aermod View licenses. For meteorological modeling, which is an input for these dispersion 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 modeling the dispersion of atmospheric pollutants. We have carried out modeling of meteorological variables with the WRF model and modeling of the pollutant’s dispersion in various areas of Chile, from complex high mountain terrain, such as complex coastal terrain, achieving excellent levels of modeling performance.
