GRIC Air Quality Monitoring Program: Comprehensive Data & Reports Overview

The GRIC DEQ Air Quality Monitoring Program encompasses a robust network of three ambient air monitoring sites dedicated to monitoring criteria pollutants, including seasonal ozone, PM10 (both filter-based and continuous), and PM2.5 (filter-based). This initiative includes special projects such as JATAP for VOC and PM2.5 speciation. The program emphasizes data validation, analysis, and quality assurance through in-house management and systematic reporting, leveraging software tools like ArcGIS, MS Excel, and specialized data platforms. Community engagement and regulatory support ensure compliance with national standards while addressing public concerns.
