A newly installed multi-axis differential optical absorption spectroscopy (MAX-DOAS) instrument on the rooftop of an 11-story campus building to provide sustained measurements of atmospheric composition over Central London. This provides crucial information about air pollution above the city and is the first long-term validation site for UV/visible space-based instruments in the UK.
