RE: UV attenuation in air
UV attenuation in air is not constant, but is strongly a function of the concentration of ozone in the air.
Loss of stratospheric ozone has resulted in a significant drop in stratospheric temperature for the 25 or so years for which we have good data (because of reduced heating of the stratosphere from UV dissociation of ozone).
Best regards.

Subject: UV attenuation in air
Can anyone point me to a reference for UV attenuation in air by
wavelength?
I've been looking and all I can find it total atmospheric attenuation.
I need information for much shorter ranges - a few meters.
