Abstract: The simultaneous operation of two NCAR ice nuclei counters and an integrating nephelometer at Mauna Loa Observatory over a period of 9 months shows concentration changes in the ice nuclei population that vary in direct ...

Abstract: Solar radiation transmission data taken at Mauna Loa exhibit a seasonal variation with the minimum in summer. On the basis of Barrett's model for the depletion of solar radiation by aerosols, it is suggested that these ...

Abstract: Nephelometry, in conjunction with a tube furnace and an Aitken nuclei counter, has been applied to the investigation of the volatile component of the aerosol budget at Cape Kumukahi, Hilo. and Mauna Loa Observatory, Hawaii. ...

Abstract: Aitken nuclei and ice nuclei concentrations in the smoke plume from an oil well fire near Glenrock, Wyo., on 14 December 1973, were found to be elevated by at least an order of magnitude as compared with the surrounding ...

Abstract: To assess the influence of anthropogenic aerosols on the physics and chemistry of clouds in the northeastern United State, aerosol and cloud-drop size distributions, elemental composition of aerosols as a function of size, ...

Abstract: Using an airborne lidar, we have measured atmospheric aerosol backscatter coefficients (differential backscatter cross section per unit volume) for 10.6 ?m wavelength laser radiation as a function of height to 5200 m for ...
