Doppler Polarimetric Radar Measurements of the Gamma Drop Size Distribution of Rain
Publisher: American Meteorological Society
Abstract: The conversion of radar reflections into rain intensities is dependent upon assumptions regarding the drop size distribution. The gamma drop size distribution contains three unknown parameters; the number of parameters ...
Investigation of the Turbulent Structure of a Cloud-Capped Mixed Layer Using Doppler Radar
Publisher: American Meteorological Society
Abstract: A new method for retrieving air velocity fluctuations in the cloud-capped boundary layer (BL) using radar reflectivity and the Doppler velocity fields is proposed. The method was developed on the basis of data obtained by ...
Combined Observational and Model Investigations of the Z–LWC Relationship in Stratocumulus Clouds
Publisher: American Meteorological Society
Abstract: In situ measurements indicate the complexity and nonunique character of radar reflectivity?liquid water content (Z?LWC) relationships in stratocumulus and cumulus clouds. Parameters of empirical (statistical) Z?LWC dependences ...
Dual-Polarization Spectral Analysis for Retrieval of Effective Raindrop Shapes
Publisher: American Meteorological Society
Abstract: Dual-polarization radar observations of precipitation depend on size?shape relations of raindrops. There are several studies presented in literature dedicated to the investigation of this relation. In this work a new ...
Coherent Scattering of Microwaves by Particles: Evidence from Clouds and Smoke
Publisher: American Meteorological Society
Abstract: Many radar measurements of the atmosphere can be explained in terms of two scattering mechanisms: incoherent scattering from particles, and coherent scattering from variations in the refractive index of the air, commonly ...
A New Technique to Categorize and Retrieve the Microphysical Properties of Ice Particles above the Melting Layer Using Radar Dual-Polarization Spectral Analysis
Publisher: American Meteorological Society
Abstract: In this study, a dual-polarization spectral analysis for retrieval of microphysical properties of ice hydrometeors is developed. It is shown that, by using simultaneous Doppler polarimetric observations taken at a 45° ...
Precipitation Measurement at CESAR, the Netherlands
Publisher: American Meteorological Society
Abstract: The Cabauw Experimental Site for Atmospheric Research (CESAR) observatory hosts a unique collection of instruments related to precipitation measurement. The data collected by these instruments are stored in a database that ...
Cloudnet
Publisher: American Meteorological Society
Abstract: The Cloudnet project aims to provide a systematic evaluation of clouds in forecast and climate models by comparing the model output with continuous ground-based observations of the vertical profiles of cloud properties. ...
