Nope, no data at all on wavelength blocking, at least that I could find with only a few minutes of free time to look the site over. I did find this interesting statement: "Is carbon dioxide a harmful air pollutant, or is it an amazingly effective aerial fertilizer?" Venus must be an incredibly fertile place, by that standard. --- diveboss@xmission.com wrote:

Chuck, maybe you can find the answer here.
Quoting Chuck Hards <chuckhards@yahoo.com>:
Several years ago I made the comment to a friend who happens to be a career scientist that sometimes the sky didn't seem as blue as it was when I was younger. More greenish, espeically noticeable at low sun angles. I can't remember his exact answer, but he said it had to do with the increased concentrations of carbon dioxide and other greenhouse gasses in the atmosphere, as well as certain man-made particulates.
Would an increase in CO2 level (or other industrial pollutants) tend to make the atmosphere more opaque to certain wavelengths of light? Is ground-based astronomy eventually going to take a hit because of air pollution?
