One Long Sunday

Station Weekend Effects as Predictors of Ozone Change under a 2020 Lockdown in an Urban Monitoring Network

A paper from the School of Settled Matters and the School of Underlying Conditions estimates, for each of eleven stations in one coastal city's air-quality network, how much ozone rose per unit fall in nitrogen oxides between a pre-pandemic Sunday and a midweek day, and uses that weekend sensitivity to predict each station's ozone change over a thirteen-week 2020 lockdown. The prediction holds to within 0.6 ppb at nine stations, where total oxidant barely moved and the rise was reduced titration, and fails at a freight-corridor roadside station, where the lockdown removed different vehicles from those a Sunday removes, and at a suburban station downwind of the centre, where ozone rose 3.1 ppb more than any weekend had implied.
