Dataset of Ozone (O3) and Carbon Monoxide (CO) concentrations measured at a neighborhood-level air quality monitoring station

The dataset was collected in Cadereyta, Nuevo León, Mexico, from March 1 to June 30, 2024. The monitoring station is located in an area with varying characteristics related to potential sources of carbon monoxide (CO) emissions and other ozone precursor pollutants (O3). This air quality monitoring station is situated in a residential area between two boulevards with heavy vehicular traffic, as well as a nearby highway (less than 600 meters away) that sees significant traffic from high-capacity tractor-trailer trucks. Additionally, an oil refining plant is located within a distance of less than 4.5 km. O3 concentrations (ppb) were measured using a ZE25 sensor, while CO concentrations (ppm) were obtained with a low-cost, calibrated MQ series sensor, sampling every 3 minutes. Meteorological variables, including temperature (°C), relative humidity (%), and barometric pressure (hPa), were measured with a Bosch BME280 sensor.
