In one of his articles Dane Wigington refers to the fact that not only UVA reaches the surface but also UVB and even UVC. The latter one is not supposed to reach the surface at all.

These high levels of UVB and UVC are one of the arguments to prove objectively the changed atmosphere by the releasal of artificial aerosols.

As Dane Wigington has got these data from his own efforts and only for the Westcoast of the United States it is of value for this argumentation to have other data resources from other locations as well.

Here is one of an UVB-level graph from Diekirch in Luxembourg:
