NUMBER 3, MARCH 1992 "Multi Wavelength Measurements of
Atmospheric Turbidity and Determination of the Fluctuations in
Total Ozone over Antarctica," R. Singh (Radio Sci. Div., Nat.
Physical Lab., New Delhi 110012, India), P.K. Pasricha et al.,
Atmos. Environ., 26A(4), 525-530, 1992. Sun photometer
measurements were made at 310, 368 and 500 nm during several
Indian expeditions to Antarctica, and at 368 and 500 nm over the
ocean on a cruise to one of the expeditions. Optical depth and
turbidity due to atmospheric haze aerosols were computed. The
wavelength 310 nm, towards the upper limit of the UV-B band that
is highly absorbed, is best suited for monitoring fluctuations
in total ozone. "More Rapid Polar Ozone Depletion through the
