Data sets

ICOZA: Atmospheric species measurements of OH, HONO, HO2, NO, NO2, NOy, O3, SO2 and CO from Weybourne Atmosphere Observatory July 2015 L. Crilley, L. Kramer, C. Reed, J. D. Lee, R. Massey-Woodward, L. Whalley, G. Forster, and B. Bandy

Short summary
Measurements of OH, HO2 and RO2 radicals and also OH reactivity were made at a UK coastal site and compared to calculations from a constrained box model utilising the Master Chemical Mechanism. The model agreement displayed a strong dependence on the NO concentration. An experimental budget analysis for OH, HO2, RO2 and total ROx demonstrated significant imbalances between HO2 and RO2 production rates. Ozone production rates were calculated from measured radicals and compared to modelled values.
