Aerometric Data Analysis

What are the characteristics of ozone, particulate matter, or hazardous air pollutant concentrations in a city, region, or state? Is the air quality improving over time? What role does transport of pollutants from other regions play in an area’s air quality? What emissions sources are contributing to air quality problems in an area? STI data analysts are experienced at assembling, validating, analyzing, interpreting, and presenting data to address these and other questions. We employ graphical and statistical methods to characterize spatial and temporal patterns in ambient pollutant concentrations, quantify pollutant trends, quantify the contribution of important sources to ambient concentrations, assess relationships among pollutants, and assess the capability of the networks to meet monitoring objectives. Aerometric data analysis projects span all business areas at STI and, thus, rely on collaborative efforts among staff with extensive knowledge of data quality assurance and validation, meteorology, atmospheric chemistry, statistics, emissions, exposure, geographic information systems (GIS), and policy.
