MAX-DOAS measurements of atmospheric composition over Central London
Our MAX-DOAS has been operating from a UCL Bloomsbury campus rooftop since July 2022, making routine measurements of urban nitrogen dioxide, nitrous acid, and formaldehyde, informing us of the complex mix of atmospheric chemicals affecting air quality in London, and for validating observations from space-based sensors.
