Rancho & Teddy Air Monitoring Station, Las Vegas, Nevada | NEAR ROAD Network

Rancho & Teddy is an air monitoring station located at 2755 South Rancho Drive in Las Vegas, Nevada, United States. It operates under the NEAR ROAD network, which focuses on measuring air pollution near major roadways to assess traffic-related emissions. The station is managed by the Clark County Department of Environment and Sustainability (DES), a key agency for local air quality management. The station is part of the broader US EPA Air Quality System (AQS) monitoring network, which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, nitrogen dioxide, and sulfur dioxide. NEAR ROAD stations are strategically sited to capture pollutant gradients near highways, providing representative data for exposure assessments. The last reported sample date is September 30, 2025, indicating ongoing operations. Environmental monitoring in Las Vegas is critical due to the city's rapid urban growth, desert climate, and high traffic volumes. The Rancho & Teddy station contributes to understanding local air quality trends, supporting public health advisories and regulatory compliance with National Ambient Air Quality Standards (NAAQS). Its roadside location helps evaluate the effectiveness of emission control policies.

Las Vegas experiences a desert climate with frequent temperature inversions that can trap pollutants near the surface. The NEAR ROAD network addresses the need for monitoring traffic-related air pollution, which includes fine particulate matter (PM2.5) and nitrogen oxides (NOx). Clark County's air quality program aligns with EPA standards to protect public health, especially in urban corridors where vehicle emissions are concentrated.
