Modeling of Particle and Gas Dispersion

With more than 20 years of experience in modeling the dispersion of atmospheric pollutants, we offer an advanced service for projects subject to the Environmental Impact Assessment System (SEIA) and for self-assessment of operational emissions scenarios.

Importance of the Service

We use air quality models as key tools to assess the impact of emissions on air and human health, following the “Guide for the Use of Air Quality Models” established by the SEA in March 2023.

Features of Our Service

Recommended Models: We implement Calpuff and Aermod models, recommended by the SEA guide, for simulating the dispersion of particles, gases, and odors.

Meteorological Modeling: We use the WRF-ARW model to generate the necessary meteorological information for these dispersion models.

Services Offered

Statistical analysis using OpenAir-Project and Python to develop a baseline.

Complete modeling of one year's meteorology.

Annual modeling of the dispersion and deposition of particles, gases, and odors.

Assimilation of surface and altitude meteorological data.

Environmental impact evaluation.

Determination of influence areas.

Study on the deposition of toxic pollutants.

Dispersion analysis near large bodies of water.

Impact of point and area sources.

Studies of short and long-range pollutant transport.

Our Experience

We have worked in high mountain and coastal terrains, achieving high performance in our models. Among our clients are CODELCO, Anglo American, BHP Billiton, ENAP Refinerías, Antofagasta Minerals, SQM, CAP, Aes Andes, Quimetal, Gestiona, among other important companies.
