Air Quality Strategy and Compliance
Air Quality Strategy
We help define the air quality pathway for a project through early technical review, study planning and compliance support.
Service areas
Our services address the air quality needs that arise throughout a project, from early strategy and assessment to compliance, monitoring and follow-up.
Air Quality Modelling
Dispersion Modelling and Impact Assessment
We undertake air quality impact assessment using dispersion models supported by observed or WRF-derived meteorology, applying specialist modelling where required.
Atmospheric dispersion modelling
Assessment of impacts using WRF, CALPUFF, AERMOD, CAMx and WRF-Chem according to the objective, scale and technical requirement.
Meteorological inputs and WRF modelling
Preparation of representative meteorological inputs, including WRF simulations where required.
Odour assessment and dispersion modelling
Assessment of odour impacts at communities and sensitive receptors using appropriate dispersion methods.
Atmospheric Emissions
Atmospheric Emissions Assessment
We prepare traceable emissions inventories and supporting analyses for assessment, modelling, reporting and offset planning.
Atmospheric emissions inventories
Calculation and reporting of emissions by source, pollutant and project phase.
Reporting and compliance support
Technical support for emissions reporting and compliance requirements before the relevant Chilean authority.
Emissions offset planning
Assessment and development of offset measures to meet project commitments.
Baseline Assessment and Monitoring
Baseline Air Quality Assessment and Monitoring
We characterise existing air quality conditions, assess monitoring information and support environmental assessment, monitoring programmes and compliance.
Baseline air quality assessment
Characterisation of existing conditions using public datasets and monitoring measurements.
Baseline meteorological assessment
Analysis of meteorological and climatological data relevant to the project setting.
Monitoring network design
Strategic distribution of meteorological and air quality stations.
Monitoring network audit
Verification of efficient operation and reliable data recording.
Detailed services
Early air quality strategy and technical review
We identify constraints, assess available information and define an appropriate air quality assessment pathway before key project decisions are made.
Compliance with Air Pollution Prevention and Decontamination Plans (PPDA)
We provide technical support to interpret and address requirements under Chilean Air Pollution Prevention and Decontamination Plans, combining compliance review with applied air quality analysis.
Atmospheric dispersion modelling
We apply dispersion models to estimate pollutant concentrations, potential areas of influence and impacts at relevant receptors, supporting environmental assessment and project decisions in Chile and the region.
Meteorological inputs and WRF modelling
We process meteorological observations and develop WRF simulations where required to provide a robust meteorological basis for dispersion modelling.
Odour assessment and dispersion modelling
We assess odour emissions and dispersion to evaluate potential effects on communities and sensitive receptors.
Atmospheric emissions inventories
We quantify emissions by source, pollutant, project phase and operating scenario, providing traceable inputs for assessment, modelling and compliance.
Reporting and compliance support
We support emissions reporting and compliance processes through calculations, review of technical documentation and responses to authority requirements.
Emissions offset planning
We assess and develop emissions offset measures, supporting compliance and project commitments through technically grounded evaluation of alternatives.
Baseline air quality assessment
We characterise existing air quality conditions using available datasets, monitoring measurements and relevant technical information.
Baseline meteorological assessment
We analyse meteorological and climatological data to characterise the atmospheric setting relevant to air quality studies.
Monitoring network design
We design meteorological and air quality monitoring networks with regard to location, representativeness and the intended use of the data.
Monitoring network audit
We review monitoring network operation and assess the quality, consistency and technical usability of meteorological and air quality data.
