Air quality monitoring at Universidad Iberoamericana, Mexico City: Ozone and meteorological data during the rainy and ozone seasons (Mar–Nov 2024)

Abstract

This dataset contains hourly-averaged measurements of ozone and meteorological variables collected between March 1 and November 30, 2024, at Universidad Iberoamericana, Mexico City (latitude: 19.372292, longitude:99.263679). The data capture conditions across both the ozone season (March-June) and the rainy season (May-October) in a high-altitude urban environment. Variables include ozone concentration (ppb), temperature ( °C), relative humidity (%), wind direction (°), wind speed (m/s), atmospheric pressure (hPa), accumulated precipitation (mm), and solar radiation (W/m²). The dataset was obtained using a calibrated low-cost sensor system, which transmitted data to the cloud for subsequent download in CSV format. This open-access dataset is intended to support research on the interactions between meteorological conditions and air quality. It can be reused in studies focused on air quality modelling, atmospheric dynamics, environmental monitoring, or urban climate in megacities with similar characteristics.
