Liquid Water Path and Plane-Parallel Albedo Bias during ASTEX
Publisher: American Meteorological Society
Abstract: Inhomogeneous distributions of liquid water like those observed in real clouds generally reflect less solar radiation than idealized uniform distributions assumed in plane-parallel theory. Here the authors determine cloud ...
Surface-Based Remote Sensing of Marine Boundary-Layer Cloud Properties
Publisher: American Meteorological Society
Abstract: Surface-based measurements are used to define some of the important macrophysical and optical properties of marine clouds. These measurements were taken during five different marine field programs. A progression is made ...
Windowed and Wavelet Analysis of Marine Stratocumulus Cloud Inhomogeneity
Publisher: American Meteorological Society
Abstract: To improve radiative transfer calculations for inhomogeneous clouds, a consistent means of modeling inhomogeneity is needed. One current method of modeling cloud inhomogeneity is through the use of fractal parameters. This ...
Influences of Storm-Embedded Orographic Gravity Waves on Cloud Liquid Water and Precipitation
Publisher: American Meteorological Society
Abstract: This study illustrates opportunities for much improved orographic quantitative precipitation forecasting, determination of orographic cloud seedability, and flash flood prediction through state-of-the-art remote sensing ...
Investigations of a Winter Mountain Storm in Utah. Part II: Mesoscale Structure, Supercooled Liquid Water Development, and Precipitation Processes
Publisher: American Meteorological Society
Abstract: A comprehensive analysis of a deep winter storm system during its passage over the Tushar Mountains of southwestern Utah is reported. The case study, drawn from the 1985 Utah/NOAA cooperative weather modification experiment, ...
The Albedo of Fractal Stratocumulus Clouds
Publisher: American Meteorological Society
Abstract: An increase in the planetary albedo of the earth-atmosphere system by only 10% can decrease the equilibrium surface temperature to that of the last ice age. Nevertheless, albedo biases of 10% or greater would be introduced ...
Relationship between Ice Water Path and Downward Longwave Radiation for Clouds Optically Thin in the Infrared: Observations and Model Calculations
Publisher: American Meteorological Society
Abstract: A vertically pointing 3.2-cm radar is used to observe altostratus and cirrus clouds as they pass overhead. Radar reflectivities are used in combination with an empirical Zi-IWC (ice water content) relationship developed ...
Comparison of Infrared Atmospheric Brightness Temperatures Measured by a Fourier Transform Spectrometer and a Filter Radiometer
Publisher: American Meteorological Society
Abstract: Increased interest in using atmospheric brightness temperature measurements from simple infrared radiometers combined with radars and lidars has prompted the investigation of their accuracy for various sky conditions. In ...
A Remote-Sensing View of a Freezing-Rain Storm
Publisher: American Meteorological Society
Abstract: A destructive freezing-rain storm on 15 February 1990 was observed intensively with advanced ground-based remote sensors and conventional instruments by the Lake Ontario Winter Storms (LOWS) project in upstate New York. A ...
Comparisons of Ice Cloud Parameters Obtained by Combined Remote Sensor Retrievals and Direct Methods
Publisher: American Meteorological Society
Abstract: Ice cloud microphysical parameters derived from a remote sensing method that uses ground-based measurements from the Environmental Technology Laboratory?s Ka-band radar and an IR radiometer are compared to those obtained ...
