We already knew of the pollution induced
smog, a
hazy condition produced by particle pollution. We also knew of
light pollution due to the atmosphere scattering of city lights and radio FM signals. It used to be that only astronomers were disturbed by this phenomena, but now the RF apectrum is so overwhelmed with new RF sources (cell phones, 802.11...) that it now has an ability to pollute the
readings made by meteorology satellites who have intruments that can detect only a few frequency bands.
