Short summary
We report long-term and spatially resolved hourly measurements of organic carbon (OC) and elemental carbon (EC) concentrations in ambient particulate matter in Riyadh, Saudi Arabia. Our analysis suggests both local vehicular emissions and regional sources (e.g., oil extraction and refining) were strong influences. Our work informs the development of pollution control strategies for Riyadh.
