Measurement of the Size Distribution and CCN Supersaturation Spectrum of Submicron Aerosols over the Ocean
Publisher: American Meteorological Society
Abstract: Data on the submicron aerosol size distribution, the supersaturation spectrum, and the relationship between dry size and critical supersaturation taken during a cruise of the USNS Hayes from Norfolk, Virginia, to Piraeus, ...
Experimental Determination of the Eddy Diffusion Coefficient Over the Open Ocean from Atmospheric Electric Measurements
Publisher: American Meteorological Society
Abstract: The method of determining the eddy diffusivity over the open ocean either from profiles of the average electric filed or from average values of space charge and electric field measured near the sea surface is discussed. ...
The Mobility of Tropospheric Ions Above the Exchange Layer
Publisher: American Meteorological Society
Abstract: Measurements of both polar conductivities, the densities and mobility distributions of small ions, electric field intensity, and other related atmospheric variables were made from an airplane from 30 m to 5.6 km. A Blackwood ...
Airship Measurements of Ship’s Exhaust Plumes and Their Effect on Marine Boundary Layer Clouds
Publisher: American Meteorological Society
Abstract: High-resolution aerosol, trace gas, and cloud microphysical measurements were made from an airship during transects across ships exhaust plumes advecting downwind of ships in the marine boundary layer (MBL). This study was ...
Airship Measurements of Aerosol Size Distributions, Cloud Droplet Spectra, and Trace Gas Concentrations in the Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: The use of an airship as a platform to conduct atmospheric chemistry, aerosol, and cloud microphysical research is described, and results from demonstration flights made off the Oregon coast are presented. The slow speed ...
Accuracy Limitations on CCN Measurements with Thermal Gradient Diffusion Chambers
Publisher: American Meteorological Society
Abstract: Limitations on the accuracy of CCN counts obtained with thermal gradient diffusion cloud chambers (TGDCC) are discussed. Evidence presented here regarding 1) the absence of a well-defined plateau when the number of CCN in ...
The Electrical Shielding Layer Around Charged Clouds and its Role in Thunderstorm Electricity
Publisher: American Meteorological Society
Abstract: The system of differential equations which governs the equilibrium charge distribution around a charged cloud located in an atmosphere with constant ionization is solved numerically for clouds with differing water content. ...
Vertical Profiles of CCN at Various Geographical Locations
Publisher: American Meteorological Society
Abstract: Measurements of the number density, volatility and supersaturation spectra of CCN during aircraft soundings to about 15,000 ft MSL over Arizona, Central Pacific, Alaska, and in a convective region over Florida, and on five ...
