In Situ Observations of Cirrus Cloud Microphysical Properties Using the Counterflow Virtual Impactor
Publisher: American Meteorological Society
Abstract: This study presents a new technique for making in situ measurements of cirrus cloud microphysical properties. Sampling of cirrus clouds was performed using a counterflow virtual impactor (CVI). The CVI was used to sample ...
Performance Characteristics of a High-Sensitivity, Three-Wavelength, Total Scatter/Backscatter Nephelometer
Publisher: American Meteorological Society
Abstract: As designed in the 1940s by Beuttell and Brewer, the integrating nephelometer offers a direct method of measuring light scattering by airborne particles without assumptions about particle composition, shape, or physical ...
Intercomparisons and Aerosol Calibrations of 12 Commercial Integrating Nephelometers of Three Manufacturers
Publisher: American Meteorological Society
Abstract: This study determined measured and Mie-calculated angular signal truncations for total and backscatter TSI, Inc., nephelometers, as a function of wavelength and for particles of known size and composition. Except for the ...
ARM Southern Great Plains Site Observations of the Smoke Pall Associated with the 1998 Central American Fires
Publisher: American Meteorological Society
Abstract: Drought-stricken areas of Central America and Mexico were victimized in 1998 by forest and brush fires that burned out of control during much of the first half of the year. Wind currents at various times during the episode ...
