SSM/I Brightness Temperature Corrections for Incidence Angle Variations
Publisher: American Meteorological Society
Abstract: The incidence angles of the SSM/I radiometers on the DMSP satellites vary from satellite to satellite and exhibit variations of up to 1.5° during one orbit. The effects of these variations on the measured brightness ...
A Rain-Rate Retrieval Algorithm for Attenuated Radar Measurements
Publisher: American Meteorological Society
Abstract: A dynamic regularization scheme for rain-rate retrievals from attenuated radar measurements is presented. Most regularization techniques, including the optimal estimation method, use the state-space parameters to regularize ...
Latent Heat Flux over the North Atlantic Ocean—A Case Study
Publisher: American Meteorological Society
Abstract: Nimbus-7 SMMR data and ship observations are combined to compute the latent heat flux using the bulk aerodynamic method. Sea surface temperature (SST) and the surface humidity are determined with the microwave data. The ...
Estimating Longwave Net Radiation at Sea Surface from the Special Sensor Microwave/Imager (SSM/I)
Publisher: American Meteorological Society
Abstract: A neural network is used to calculate the longwave net radiation (Lnet) at the sea surface from measurements of the Special Sensor Microwave/Imager (SSM/I). The neural network applied in this study is able to account largely ...
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 ...
Multiple Scattering Effects in Pulsed Radar Systems: An Intercomparison Study
Publisher: American Meteorological Society
Abstract: In this paper, two different numerical methods capable of computing multiple scattering effects in pulsed-radar systems are compared. Both methods are based on the solution of the time-dependent vectorial form of the ...
Improving Estimates of Heavy and Extreme Precipitation Using Daily Records from European Rain Gauges
Publisher: American Meteorological Society
Abstract: The long-term variability in heavy precipitation characteristics over Europe for the period 1950?2000 is analyzed using high-quality daily records of rain gauge measurements from the European Climate Assessment (ECA) ...
PARSIVEL Snow Observations: A Critical Assessment
Publisher: American Meteorological Society
Abstract: The performance of the laser-optical Particle Size Velocity (PARSIVEL) disdrometer is evaluated to determine the characteristics of falling snow. PARSIVEL?s measuring principle is reexamined to detect its limitations and ...
Characterization of Precipitating Clouds by Ground-Based Measurements with the Triple-Frequency Polarized Microwave Radiometer ADMIRARI
Publisher: American Meteorological Society
Abstract: A groundbreaking new-concept multiwavelength dual-polarized Advanced Microwave Radiometer for Rain Identification (ADMIRARI) has been built and continuously operated in two field campaigns: the Convective and Orographically ...
Investigations of Backscatter Differential Phase in the Melting Layer
Publisher: American Meteorological Society
Abstract: ackscatter differential phase δ within the melting layer has been identified as a reliably measurable but still underutilized polarimetric variable. Polarimetric radar observations at X band in Germany and S band in the ...
