Abstract:

In two balloon flights over Laramie, Wyoming, simultaneous measurements of aerosol backscatter and total aerosol scatter were successfully obtained. The data have been analyzed and used to directly measure the extinction-to-backscatter ratio under the assumption that the aerosols are relatively non-absorbing small imaginary component to the index of refraction. The results are consistent with previous estimates of the extinction-to- backscatter ratio, although very little information is available relevant to direct measurements of this important parameter. It is concluded that the new instruments and techniques employed here will provide a practical method of obtaining a wealth of new information concerning the extinction-to-backscatter ratio of tropospheric aerosols.
