RISPotential of Higher-Order Moments and Slopes of the Radar Doppler Spectrum for Retrieving Microphysical and Kinematic Properties of Arctic Ice Clouds
Publisher: American Meteorological Society
Abstract: etrievals of ice-cloud properties from cloud-radar observations are challenging because the retrieval methods are typically underdetermined. Here, the authors investigate whether additional information can be obtained from ...
Ground-Based Temperature and Humidity Profiling Using Spectral Infrared and Microwave Observations. Part I: Simulated Retrieval Performance in Clear-Sky Conditions
Publisher: American Meteorological Society
Abstract: Two independent ground-based passive remote sensing methods are used to retrieve lower-tropospheric temperature and humidity profiles in clear-sky cases. A simulation study for two distinctly different climatic zones is ...
Potential of Dual-Frequency Radar and Microwave Radiometer Synergy for Water Vapor Profiling in the Cloudy Trade-Wind Environment
Publisher: American Meteorological Society
Abstract: High-resolution boundary-layer water vapor profile observations are essential for understanding the interplay between shallow convection, cloudiness and climate in the trade wind atmosphere. As current observation techniques ...
An Integrated Approach toward Retrieving Physically Consistent Profiles of Temperature, Humidity, and Cloud Liquid Water
Publisher: American Meteorological Society
Abstract: A method is presented for deriving physically consistent profiles of temperature, humidity, and cloud liquid water content. This approach combines a ground-based multichannel microwave radiometer, a cloud radar, a ...
A New Criterion to Improve Operational Drizzle Detection with Ground-Based Remote Sensing
Publisher: American Meteorological Society
Abstract: AbstractLight shallow precipitation in the form of drizzle is one of the mechanisms for liquid water removal, affecting cloud lifetime and boundary layer dynamics and thermodynamics. The early formation of drizzle drops ...
Advances in Continuously Profiling the Thermodynamic State of the Boundary Layer: Integration of Measurements and Methods
Publisher: American Meteorological Society
Abstract: This paper describes advances in ground-based thermodynamic profiling of the lower troposphere through sensor synergy. The well-documented integrated profiling technique (IPT), which uses a microwave profiler, a cloud ...
Developing and Evaluating Ice Cloud Parameterizations for Forward Modeling of Radar Moments Using in situ Aircraft Observations
Publisher: American Meteorological Society
Abstract: bserving ice clouds using zenith pointing millimeter cloud radars is challenging because the transfer functions relating the observables to meteorological quantities are not uniquely defined. Here, the authors use a spectral ...
A W-Band Radar–Radiometer System for Accurate and Continuous Monitoring of Clouds and Precipitation
Publisher: American Meteorological Society
Abstract: AbstractA new 94-GHz frequency-modulated continuous wave (FMCW) Doppler radar?radiometer system [Jülich Observatory for Cloud Evolution (JOYCE) Radar?94 GHz (JOYRAD-94)] is presented that is suitable for long-term continuous ...

Absorption Properties of Supercooled Liquid Water between 31 and 225 GHz: Evaluation of Absorption Models Using Ground-Based Observations
Publisher: American Meteorological Society
Abstract: icrowave radiometers (MWR) are commonly used to quantify the amount of supercooled liquid water (SLW) in clouds; however, the accuracy of the SLW retrievals is limited by the poor knowledge of the SLW dielectric properties ...
