The Coastal Watch Association operates a community focused air monitoring program designed to provide residents with transparent information about local air quality. The network currently uses non-regulatory monitors to track key pollutants including ozone (O₃), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), volatile organic compounds (VOCs), particulate matter smaller than 10 microns (PM₁₀), and fine particulate matter (PM₂.₅).
Data from these monitors helps identify pollution trends and potential impacts along the Coastal Bend. The program is expanding its network by adding regulatory-grade BAM 1022 particulate monitors alongside additional non-regulatory sensors developed by the University of Texas at Arlington to improve coverage and data reliability across the region.
