EVLA Memo 131 Measurements of C-Band EVLA Antenna Polarization
A simple method for determining absolute antenna cross-polarization is described. Observations using this method were taken at C-band and the results are shown. The wide-band EVLA circular polarizers have high cross-polarization, exceeding 5% at most frequencies on most antennas. However, orthogonality between the RCP and LCP outputs is maintained, resulting in baseline-based cross-polarization...
متن کاملA Distributed Framework for Remote Monitoring of Hurricane Wind Pressures and Wind Speeds using Wireless Sensor Networks
This paper presents a generalized software architecture used in a real sensor network application to provide the necessary communications infrastructure between remote sensor units and centralized server. The architecture utilizes existing wireless networking standards (IEEE 802.11 and HSDPA) and relies heavily on built in capabilities of Microsoft .NET development framework. Through layered an...
متن کاملCloud Microphysics Retrieval Using S-Band Dual-Polarization Radar Measurements
The recent deployment of multiparameter, polarimetric radars provides the impetus for development of microphysical retrievals. The primary objective of this paper is to describe a particle classification technique that makes use of polarimetric radar observations. The particle classification technique is computationally simple enough to be implemented for real-time research and operational fiel...
متن کاملAir–Sea Enthalpy and Momentum Exchange at Major Hurricane Wind Speeds Observed during CBLAST
Quantifying air–sea exchanges of enthalpy and momentum is important for understanding and skillfully predicting tropical cyclone intensity, but the magnitude of the corresponding wind speed–dependent bulk exchange coefficients is largely unknown at major hurricane wind speeds greater than 50 m s. Since direct turbulent flux measurements in these conditions are extremely difficult, the momentum ...
متن کاملForecasting Solar Wind Speeds
By explicitly taking into account effects of Alfvén waves, I derive from a simple energetics argument a fundamental relation which predicts solar wind (SW) speeds in the vicinity of the earth from physical properties on the sun. Kojima et al. recently found from their observations that a ratio of surface magnetic field strength to an expansion factor of open magnetic flux tubes is a good indica...
