Parameterization of Reflectivity for Broken Cloud Fields
Publisher: American Meteorological Society
Abstract: To parameterize the reflected fluxes from broken cloud fields, Monte Carlo calculations are performed for several cumulus cloud fields. The results with the effects of cloud-cloud interaction and enhanced illuminated area ...
Reflected Solar Flux for Horizontally Inhomogeneous Atmospheres
Publisher: American Meteorological Society
Abstract: Reflected fluxes are investigated for a spatially heterogeneous medium. Multidimensional radiative transfer equations for a collimated source are solved as a standard eigenvalue problem (discrete-ordinate method) by using ...
Effects Due to Cloud Geometry on Biases in the Albedo Derived from Radiance Measurements
Publisher: American Meteorological Society
Abstract: The usual procedure in determining the earth's radiation budget is that observed radiances are first used to derive cloud properties. The properties are then used in a one-dimensional model to deduct cloud albedos. This ...
Retrieval of Arbitrarily Shaped Raindrop Size Distributions from Wind Profiler Measurements
Publisher: American Meteorological Society
Abstract: An efficient iterative retrieval method for arbitrarily shaped raindrop size distributions (ITRAN) is developed for Doppler spectra measured with a wind profiler. A measured Doppler spectrum is a convolution of the ...
Broken Cloud Biases in Albedo and Surface Insolation Derived from Satellite Imagery Data
Publisher: American Meteorological Society
Abstract: Radiative transfer calculations for a one-dimensional column model of the atmosphere containing a plane-parallel, homogeneous cloud are used to show that the common procedure of assuming that fields of view for high ...
Evaluation of Three-Beam and Four-Beam Profiler Wind Measurement Techniques Using a Five-Beam Wind Profiler and Collocated Meteorological Tower
Publisher: American Meteorological Society
Abstract: In this paper a five-beam wind profiler and a collocated meteorological tower are used to estimate the accuracy of four-beam and three-beam wind profiler techniques in measuring horizontal components of the wind. In the ...
