UAHuntsville X-Band Profiling Radar (XPR)
Dustin W. Phillips, University of Alabama in Huntsville, Huntsville, AL
The addition of the Vertically Pointing X-Band Profiling Radar (XPR) has further enhance the University of Alabama in Huntsville Mobile Integrated Profiling System (MIPS) by providing high resolution (1 sec in time, ~45 meters in height) vertically pointing Doppler profiles of precipitation, boundary layer structure, clouds, and biological flyers. The XPR transmits at 9405 MHz and transmits at a peak power of 25 kW The 1.8 meter dish provides a beamwidth of 1.3°. The XPR has the capability of providing sensitive precipitation profiling, cloud profiling, and profiling of the turbulent structure of the boundary layer at high spatial and temporal resolution. Because the wavelengths of the XPR and 915 MHz profiler are separated by one order of magnitude (33 cm and 3.3 cm) identifications of Bragg scattering will also be enhanced. This will allow for estimation of differential reflectivity between the 915 and 9405 MHz measurements that will provide physical insights on Bragg scattering (refractive index), hydrometers, and insect scattering properties. This paper will give a brief overview of this new instrument, looking at radar configurations, specs, and design features. Preliminary results will be shown that illustrate the dual wavelength capability within precipitation, non-precipitating clouds, convective boundary layers, nocturnal boundary layers, and biological fliers.
