Response of Cloud Supersaturation to Radiative Forcing
Publisher: American Meteorological Society
Abstract: The diffusional growth or evaporation of cloud droplets due to net emission or absorption of radiation is studied. Time dependent solutions for droplet temperatures and supersaturation are obtained, taking into account the ...
Effects of Cloud Heterogeneities on Shortwave Radiation: Comparison of Cloud-Top Variability and Internal Heterogeneity
Publisher: American Meteorological Society
Abstract: This paper examines the processes through which cloud heterogeneities influence solar reflection. This question is important since present methods give numerical results only for the overall radiative effect of cloud ...
Statistical Dependence of Albedo and Cloud Cover on Sea Surface Temperature for Two Tropical Marine Stratocumulus Regions
Publisher: American Meteorological Society
Abstract: The relationship between sea surface temperature (SST) and albedo or cloud cover is examined for two tropical regions with high values of cloud radiative forcing and persistent marine stratocumulus (mSc)?one off the west ...
Plane Parallel Albedo Biases from Satellite Observations. Part II: Parameterizations for Bias Removal
Publisher: American Meteorological Society
Abstract: Using the same satellite observations as in Part I of this paper, the authors explore ways to remove the cloud albedo bias (or plane parallel albedo bias), the difference between the plane parallel homogeneous albedo and ...
Plane Parallel Albedo Biases from Satellite Observations. Part I: Dependence on Resolution and Other Factors
Publisher: American Meteorological Society
Abstract: Due to cloud heterogeneity and the nonlinear dependence of albedo on cloud water content, the average albedo of a cloudy scene found by calculating the albedo of independent pixels within the scene tends to be different ...
Feasibility and Error Analysis of Cloud Motion Wind Extraction from Near-Simultaneous Multiangle MISR Measurements
Publisher: American Meteorological Society
Abstract: Satellite wind measurements represent an invaluable contribution to the description of the flow field over the oceans. Conventional cloud-tracking techniques suffer from the inability to simultaneously determine wind speed ...
The Effect of Cloud Sides on Reflected Solar Radiation as Deduced from Satellite Observations
Publisher: American Meteorological Society
Abstract: We report the observation of a feature that is characteristic of the reflection of solar radiation from absorbing, finite clouds. When absorption takes place, more radiation can be reflected by broken cloud fields than by ...
The Image Navigation Cloud Mask for the Multiangle Imaging Spectroradiometer (MISR)
Publisher: American Meteorological Society
Abstract: The authors have developed a cloud mask technique that may be applied to the efficient selection of ?clear enough? scenes for image navigation. While the mask can be applied generally, the motivation for its development ...
Transport of Infrared Radiation in Cuboidal Clouds
Publisher: American Meteorological Society
Abstract: The transport of infrared radiation in a single cuboidal cloud has been modeled using a variable azimuth two-stream (VATS) approximation. Computations have been made at 10 ?m for a Deirmendjian (1969) C-1 water cloud of ...
Two-Dimensional Supersonic Thrust Vectoring Using Staggered Ramps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thrust vectoring performance of a novel nozzle mechanism was numerically investigated. The nozzle was designed for supersonic, air-breathing engines using published engine data, isentropic relationships, and piecewise ...
