The European heat wave of 2018 and its promotion of the ozone climate penalty in southwest Sweden
The ozone concentration ([O3]), temperature (T) and vapour pressure deficit (VPD) during the 2018 heat wave (HW) was compared with conditions from 2013–2017. The study included one coastal and two inland sites in southwest Sweden. The positive relationship between [O3] and T was stronger in 2018. Th...
