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.

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 ...
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.

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."

This is officially the widest tornado to ever occur, with a width of 2.6 miles (4.2 km) at its peak. This is the width found by the National Weather Service based on preliminary data from University of Oklahoma RaXPol mobile radar that also sampled winds of 296 mph (476 km/h), which was used to upgrade the tornado to EF5.

Storm chasers and the RaXPol mobile research radar observed a brief satellite tornado rotating around the primary El Reno tornado; no damage was reported. [107] EF0 SSW of El Reno: Canadian: OK: 2313–2314 0.5 mi (0.80 km) 350 yd (320 m)
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)
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 ...
