Airshed professionals apply cutting-edge science and methodologies to the development of customized solutions to clients on air quality issues. The air quality team has experience in assessment of impacts in local, regional and national level.

Emission inventory (EI) is a basic necessity for planning air pollution control activities. EI provides a reliable estimate of total emissions of different pollutants, their spatial and temporal distribution, and identification and characterization of main sources. This information on EI is an essential input to air quality models for developing strategies and policies. Airshed supports the development of air pollutant and greenhouse gas emission inventories for clients and national governments to fulfill their international reporting requirements. Our services span local and national inventory and capacity building to build teams and train inventory compilers.

Airshed is equipped with all the tools require to conduct source apportionment studies based on dispersion and receptor model.

Air Dispersion Modeling is often a requirement for attaining environmental compliance approval and air permits. AIRSHED offers extensive modeling expertise across a wide variety of sectors. Airshed has worked and working closely with state meteorologists and research institutes. Airshed uses air dispersion models such as:
• AERMOD
• CALPUFF
• CAMx
• CMAQ

An expert in air toxics health risk assessment, our team comprises multidiscipline professionals such as chemical engineers, civil engineers, meteorologists, chemists, statisticians, risk assessors, toxicologists, epidemiologists, and pharmacologists.

The ability to continuously monitor and gather data to assist our client’s air compliance programs is an important part of Airshed services. Continuous monitoring systems (CMS) may take the form of continuous emissions monitors (CEMS) that directly measure stack emissions.

Aished has substantial experience in designing, operating, managing and ensuring the quality of ambient air and meteorological monitoring programs. These monitoring programs can be short-term or long-term projects including a single station or multiple stations. Airshed has experience with ambient air monitoring programs for a variety of pollutants, including:
• Sulfur Dioxide (SO2)
• Oxides of Nitrogen (NOX)
• Particulate Matter less than 10 Micron (PM10)
• Particulate Matter less than 2.5 Micron (PM2.5)
• Ozone (O3)
• Carbon Monoxide (CO)
• Volatile Organic Compounds (VOCs)
• Inorganic Compounds
• Organic Compounds
• Molecular Marker
• Biological Monitoring (Pollen, Molds, etc)

Development of high-resolution thematic layers of primary air pollutants (SOx, NOx, CO, VOCs and PM) and air pollution sources (industries, vehicles, fugitive, etc).
