Abstract: A key advantage of the National Weather Radar Testbed Phased Array Radar (PAR) is the capability to adaptively scan storms at higher temporal resolution than is possible with the Weather Surveillance Radar-1988 Doppler (WSR-88D): 1 min or less versus 4.1 min, respectively. High temporal resolution volumetric radar data are a necessity for rapid identification and confirmation of weather phenomena that can develop within minutes. The purpose of this paper is to demonstrate the PAR's ability to collect rapid-sca… Show more

“…The CASA (Cooperative Adapting and Sensing of the Atmosphere) is a network of X Band radars that address this issue but it is in early-transitional development (McLaughlin et al, 2009;Ruzanski et al, 2011). It also addresses the issue of rapid or adapting scan strategies (Heinselman et al, 2008) which is being investigated now but beyond the scope of this contribution. In any case, with increasing computing power, telecommunications, additional observations and new technology, these are exciting times.…”

“…The efficacy of the detection depends on the radar scan strategy and quality of the radar (range, azimuth resolution, cycle time, sensitivity, elevation angles, number of elevation tilts, etc Heinselman et al, 2008;Lakshmanan et al, 2006;Marshall and Ballantyne, 1975;McLaughlin et al, 2009;Vasiloff, 2001). …”

“…Within these major programs, multiple experiments are conducted each year-the EFP conducts the Spring Forecasting Experiment (e.g., Clark et al 2012) and the EWP conducts multiple experiments during this same spring time frame. For example, recent EWP experiments include the evaluation of phased array radar (Heinselman et al 2008), a network of 3-cm wavelength radars (Brotzge et al 2010), and multiradar/multisensor-blended algorithms (Lakshmanan et al 2007). Individual initiatives emanating from the GOES-R Proving Ground have been intertwined within many of these experiments and have been exceptionally productive, both in terms of scientific publications and contributions to forecast and warning operations (e.g., Kain 2004;Lakshmanan et al 2007;Kain et al 2010), yet the HWT remains largely unfunded, except for internal support from the NSSL, SPC, and WFO.…”

“…A phased-array (electronically scanning, "agilebeam"), fixed-site, S-band Doppler radar [the National Weather Radar Testbed Phased Array Radar (NWRT PAR)] has been used to obtain rapid-scan observations (volumetric update time ~30 s to 1 min) of a microburst, supercells, and a tornadic supercell (Zrnic et al 2007;Heinselman et al 2008). Having a halfpower beamwidth of ~1.5°-2.0°, the PAR's azimuthal spatial resolution is ~150 m or better only for storms within ~5-km range; such resolution is needed to resolve features as small as ~1.5 km in scale (i.e., including mesocyclones and other storm-scale features).…”
