RISEvaporative and Radiative Cooling in POST Stratocumulus
Publisher: American Meteorological Society
Abstract: uoyancy reversal by evaporative cooling in entrainment holes has a minimal influence on stratocumulus (Sc) observed during the Physics of Stratocumulus Top (POST) aircraft field study held off the California coast in 2008. ...
Retrieval of Vertical Air Motion in Precipitating Clouds Using Mie Scattering and Comparison with In Situ Measurements
Publisher: American Meteorological Society
Abstract: or the first time, the Mie notch retrieval technique is applied to airborne cloud Doppler radar observations in warm precipitating clouds to retrieve the vertical air velocity profile above the aircraft. The retrieval ...
The 2D-S (Stereo) Probe: Design and Preliminary Tests of a New Airborne, High-Speed, High-Resolution Particle Imaging Probe
Publisher: American Meteorological Society
Abstract: The design, laboratory calibrations, and flight tests of a new optical imaging instrument, the two-dimensional stereo (2D-S) probe, are presented. Two orthogonal laser beams cross in the middle of the sample volume. Custom, ...
Speciation of Organic Aerosols in the Tropical Mid-Pacific and Their Relationship to Light Scattering
Publisher: American Meteorological Society
Abstract: Although the importance of the aerosol contribution to the global radiative budget has been recognized, the forcings of aerosols in general, and specifically the role of the organic component in these forcings, still contain ...
Analysis of Humidity Halos around Trade Wind Cumulus Clouds
Publisher: American Meteorological Society
Abstract: Regions of enhanced humidity in the vicinity of cumulus clouds, so-called cloud halos, reflect features of cloud evolution, exert radiative effects, and may serve as a locus for new particle formation. Reported here are ...
Aerosol and Cloud Microphysical Characteristics of Rifts and Gradients in Maritime Stratocumulus Clouds
Publisher: American Meteorological Society
Abstract: A cloud rift is characterized as a large-scale, persistent area of broken, low-reflectivity stratocumulus clouds usually surrounded by a solid deck of stratocumulus. A rift observed off the coast of California was investigated ...
Stratocumulus Cloud Clearings and Notable Thermodynamic and Aerosol Contrasts across the Clear–Cloudy Interface
Publisher: American Meteorological Society
Abstract: ata from three research flights, conducted over water near the California coast, are used to investigate the boundary between stratocumulus cloud decks and clearings of different sizes. Large clearings exhibit a diurnal ...
Eastern Pacific Emitted Aerosol Cloud Experiment
Publisher: American Meteorological Society
Abstract: loud?radiation interactions are widely held to be the largest single source of uncertainty in climate model projections of future radiative forcing due to increasing anthropogenic emissions. The underlying causes of this ...
Racoro Extended-Term Aircraft Observations of Boundary Layer Clouds
Publisher: American Meteorological Society
Abstract: f-a-kind, extended-term cloud aircraft campaign was conducted to obtain an in situ statistical characterization of continental boundary layer clouds needed to investigate cloud processes and refine retrieval algorithms. ...
CASPER: Coupled Air–Sea Processes and Electromagnetic Ducting Research
Publisher: American Meteorological Society
Abstract: AbstractThe Coupled Air?Sea Processes and Electromagnetic Ducting Research (CASPER) project aims to better quantify atmospheric effects on the propagation of radar and communication signals in the marine environment. Such ...
