The Air Quality is much better now then normal (see attached info).
But where you live (Haarlem If I have understand correct) and where I live (near Rotterdam)
there is still Air Pollution.
That's the only positve effect of the Corona crises, clearer skys..
So whe must use these clear skys for at long as it thakes.
