RaXPol often collaborates with adjacent mobile radar projects, such as Doppler on Wheels and SMART-R. [2] Unlike its counterparts, RaXPol typically places emphasis on temporal resolution, and as such is capable of surveilling the entire local atmosphere in three dimensions in as little as 20 seconds, or a single level in less than 3 seconds.

Mobile doppler weather radars have been used on dozens of scientific and academic research projects from their invention in the late 1900s. [1] One problems facing meteorological researchers was the fact that mesonets and other ground-based observation methods were being deployed too slow in order to accurately measure and study high-impact atmospheric phenomena.

Initially receiving an official EF3 rating based on damage, the El Reno tornado was subsequently upgraded to a radar-estimated EF5 rating, the highest on the scale, based on data from a mobile radar. The University of Oklahoma 's RaXPol mobile Doppler weather radar, positioned at a nearby overpass, measured winds preliminarily analyzed as in ...
That radar, stationed near the intersection of Smith Road and Walbaum Road less than two miles (3.2 km) south of I-40, captured the "first polarimetric, rapid-scan, mobile Doppler weather radar dataset of an EF-5 tornado." [11]: 3 The RaXPol mobile Dopper radar, shown here scanning a severe thunderstorm in Oklahoma in 2013
Animated radar loop (left, storm-relative velocity; right, reflectivity) of the nearly stationary supercell thunderstorm that spawned the EF3 tornado from 5:36–7:33 p.m. CDT (2236–0033 UTC). A large, very slow-moving, and erratic tornado remained on the ground for just over an hour as it executed a cyclonic loop in Ottawa County south of ...
These smaller truck-mounted radars would replace a single large S-band radar, allowing for dual-Doppler analyses and quicker deployment times. The second planned project is the Bistatic Adaptable Radar Network (BARN) which will be integrated with existing DOWs and the COW to provide high resolution wind vector observations without the need for ...
RaXPol mobile radar data confirmed that an anticyclonic tornado, which was a satellite to the long-tracked Lake Thunderbird–Shawnee EF4 tornado, damaged trees. [29] EF1 ESE of Dallas Center: Dallas: IA: 2345 – 2348 1.43 mi (2.30 km)
Throughout the early and late 1990s, several mobile radar concepts came to be, often involving high frequency X-band radars which suffer significant attenuation, and often lack in range. Ideally, these radars would serve as research and observation platforms, covering regions scarcely covered by the NEXRAD network as a whole. [ 2 ]
