"A very recent study comparing ground and satellite measurements by an international research team at the Leibniz Institute for Tropospheric Research revealed that smoke from the forest fires on the west coast of the USA, in September 2020, travelled thousands of kilometres to Central Europe affecting the atmosphere for many days there. On Sept 11, 2020, from measurements taken in Leipzig, Germany, smog had reduced sunlight by a third."
