Use of Dual-Wavelength Radar for Snow Parameter Estimates
(American Meteorological Society, 2005)Use of dual-wavelength radar, with properly chosen wavelengths, will significantly lessen the ambiguities in the retrieval of microphysical properties of hydrometeors. In this paper, a dual-wavelength algorithm is described ... -
The Concept of a Microwave Radar with an Asymmetric Knifelike Beam for the Remote Sensing of Ocean Waves
(American Meteorological Society, 2005)The features of near-nadir probing of the ocean surface from a satellite are investigated, and a new configuration of a microwave radar for the surface slopes measurement is proposed. Numerical modeling is used to examine ... -
An Update on SURFRAD—The GCOS Surface Radiation Budget Network for the Continental United States
(American Meteorological Society, 2005)The Surface Radiation budget (SURFRAD) network was developed for the United States in the middle 1990s in response to a growing need for more sophisticated in situ surface radiation measurements to support satellite system ... -
Multi-PRI Signal Processing for the Terminal Doppler Weather Radar. Part II: Range–Velocity Ambiguity Mitigation
(American Meteorological Society, 2005)Multiple pulse-repetition interval (multi-PRI) transmission is part of an adaptive signal transmission and processing algorithm being developed to combat range?velocity (RV) ambiguity for the Terminal Doppler Weather Radar ... -
Remote Environmental Monitoring Units: An Autonomous Vehicle for Characterizing Coastal Environments
(American Meteorological Society, 2005)In oceanography, there has been a growing emphasis on coastal regions, partially because of their inherent complexity, as well as the increasing acknowledgment of anthropogenic impacts. To improve understanding and ... -
The Impact of Altimeter Sampling Patterns on Estimates of Background Errors in a Global Wave Model
(American Meteorological Society, 2005)One of the main limitations to current wave data assimilation systems is the lack of an accurate representation of the structure of the background errors. One method that may be used to determine background errors is the ... -
