Abstract: Measurements of the spectra of cloud condensation nuclei (CCN) within and near the boundaries of clouds are presented. Some of the in-cloud measurements excluded the nuclei within cloud droplets; these are interstitial CCN ...

Abstract: As part of the Cooperative Convective Precipitation Experiment (CCOPE) Aerosol Measurement Program, airborne grab samples and simultaneous nearby continuous surface measurements of CCN spectra were compared. A strong ...

Abstract: Measurements of fog drop size distribution, cloud condensation nuclei and fog condensation nuclei were made at several locations along the U.S. Pacific Coast. Wide variations in fog microstructure were associated with and ...

Abstract: Comparisons between cloud-base CCN concentrations and cloud droplet concentrations in stratus clouds over San Diego and 100 km out to sea showed a positive correlation. The supersaturation in these clouds, as derived from ...

Abstract: The state of knowledge of the particles upon which liquid droplets condense to form atmospheric water clouds is presented. The realization of cloud condensation nuclei (CCN) as a distinct aerosol subset originated with the ...

Abstract: A thermal gradient diffusion cloud chamber with a supersaturation field that increases along the path of the flow of sample is used as a cloud condensation nucleus (CCN) spectrometer. The CCN spectrum is derived from the ...

Abstract: Measurements of a mid-Atlantic clean and polluted cloud are presented. The cleaner cloud had lower concentrations of larger droplets with a broader spectrum and more drizzle drops. The first two characteristics are attributed ...

Abstract: loud microphysics and cloud condensation nuclei (CCN) measurements from two marine stratus cloud projects are presented and analyzed. Results show that the increase of cloud droplet concentrations Nc with CCN concentrations ...

Abstract: For certain field and laboratory investigations, it would he useful to have apparatus capable of yielding a continuous, instantaneously recorded measurement of the concentration of cloud nuclei. A description of such a ...

Abstract: A slightly improved version of the continuous flow diffusion cloud chamber which has been described earlier (Hudson and Squires, 1973) has been rotated so that the plates are vertical instead of horizontal, the air flow ...
