Abstract : The report completes the examination of 176 sets of data obtained with optical probing measurements in New Mexico. The study shows that: (1) A seasonal trend in the shape of the aerosol attenuation coefficient profile in the surface layer which is related to the strength of the diurnal surface convection; (2) the scavenging effects of precipitation are evident in the analysis of mid-tropospheric aerosol contents; (3) the relationship between the polar tropopause and upper tropospheric aerosol layer was less well defined in the data obtained during the latter part of 1965; (4) data from the latter part of 1965 support the findings that stratospheric aerosols have a tropical origin; and (5) the slow abatement of the Mt. Agung volcanic dust through 1965 is evident in changes in stratospheric optical thickness. (Author)
