Rosenstiel Air Monitoring Station, Miami, Florida | Environmental Monitoring

Rosenstiel is an air monitoring station located at 4600 Rickenbacker Causeway in Miami, Florida, within Miami-Dade County. Operated by the Miami-Dade County Department of Environmental Resources Management, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station's coastal siting on Virginia Key provides representative data for urban and marine-influenced air quality in the Miami metropolitan area. As part of the EPA's regulatory framework, Rosenstiel contributes to the national air quality monitoring network, which includes over 4,000 stations across the United States. The station likely measures pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, as well as meteorological parameters. The last reported sample date is September 30, 2025, indicating ongoing data collection and reporting continuity. The environmental significance of Rosenstiel lies in its role in tracking air quality trends in a densely populated urban area with unique coastal influences. Data from this station supports public health advisories, regulatory compliance, and research on air pollution transport from local sources such as traffic, industry, and maritime activities. The station's long-term operation contributes to the EPA's mission to protect human health and the environment through comprehensive air monitoring.

Miami's air quality is influenced by a mix of urban emissions, including vehicle traffic, port activities, and industrial sources, as well as natural factors like sea salt aerosols and Saharan dust. The Rosenstiel station's coastal location provides critical data on the interaction between urban pollution and marine air masses. Monitoring at this site helps assess compliance with EPA NAAQS and supports studies on ozone formation in subtropical climates, where high solar radiation and temperatures enhance photochemical reactions.
