Has air quality improved during lockdowns?
Delhi has had much cleaner air during the Covid-19 lockdowns, whereas we do not find the same improvement in PM2.5 levels in Oslo, Norway.
Lockdown
Oslo – less cars but bad air
Oslo, Norway, is like many other cities under Corona virus lockdown. Less traffic let us expect good air quality, but the opposite proved true for the end of March. We investigate reasons behind the high PM2.5 values.
PM2.5 levels drop in Wuhan, China
PM2.5 levels drop by almost 40% after the quarantine in Wuhan, China. We expect reductions in air pollution for the rest of the world as the pandemic develops.
