In brief
The network of 18 stations measures particulate matter, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide while tracking weather variables. Real‑time data feeds an AQI scale that triggers health advisories for vulnerable populations. Mobile laboratories supplement stationary sites in areas requiring extra attention.
Saudi Arabia’s National Center for Environmental Compliance launched a 24‑hour air‑quality monitoring network of 18 stations across Jeddah, reporting the first readings on November 6, 2026, according to the Saudi Press Agency (SPA). The system delivers continuous measurements of fine and inhalable particulate matter, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide, all of which feed a real‑time Air Quality Index (AQI) that alerts authorities and the public when thresholds are breached.
The 18 monitoring points are geographically spread, covering residential areas, major roads, industrial sites, and the coast. SPA notes that the network includes stations in Al‑Matar, Obhur, Dahaban, Buraiman, Al‑Rawdah, Al‑Jami’ah, Al‑Khumrah, the Jeddah Historic District and the industrial zone. The layout is designed to capture spatial variations in pollutant concentrations and to identify trends over time.
Operational Details
Each station runs 24 hours a day, transmitting data on temperature, humidity, wind speed and direction, and visibility—variables that influence pollutant dispersion. The National Center for Meteorology contributes complementary weather data to explain how winds and sea breezes distribute air contaminants across the city.
SPA emphasizes that the AQI classifies readings into six levels—Good, Moderate, Unhealthy, Severe and Hazardous—allowing targeted health advisories for children, older adults, pregnant women and those with asthma or cardiac conditions. When readings exceed approved limits, health officials can issue alerts and guidance to mitigate exposure.
Mobile laboratories are deployed to support monitoring in locations deemed to need additional attention, ensuring the network remains comprehensive and responsive to Jeddah’s dynamic air‑quality conditions.
