Simultaneous profiles of aerosol backscatter ratio were measured over Lauder, New Zealand (45°S, 170°E) on the night of November 24, 1992. Instrumentation comprised two complementary lidar systems and a backscattersonde, to give measurements at wavelengths 351, 490, 532 and 940 nm. The data from the lidars and the backscattersonde were self‐consistent, enabling the wavelength dependence of aerosol backscatter to be determined as a function of altitude. This wavelength‐dependence is a useful parameter in radiative transfer calculations. In the stratosphere, the average wavelength exponent between 351 and 940 nm was −1.23±0.1, which was in good agreement with values derived from measured physical properties of aerosols.
