Researchers at the Advanced Radar Research Center (ARRC) are leading the initiative, supported by NSF's Mid-scale Research Infrastructure-1 program. The new systems will offer exceptional capabilities to address significant observational deficiencies within the atmospheric science community.
KaRVIR will be a pioneering platform, distinguished as the only mobile, dual-Doppler Ka-band imaging radar system in the United States. Its mobile design aims to facilitate field campaigns, help scientists better understand the science of clouds, examine intricate atmospheric flows, and visualize the dynamics and structure of smoke plumes and wildfires.
Ka-band radar operates at a higher frequency compared to many other weather radars. This elevated frequency allows for the detection of a diverse range of particle sizes, a capability that is not always achievable with mid- and low-frequency radars. Such a level of detail represents a significant advancement in the study of phenomena like cloud development and the behavior and spread of fires.
The initiative will take advantage of the advanced radar development at the ARRC. KaRVIR will integrate the engineering and meteorological expertise of OU to create a radar system capable of observing intricate atmospheric details in twenty seconds or less.
KaRVIR is a scientific game-changer. It will provide four-dimensional observation of clouds, precipitations, and winds, unlocking new understanding of weather systems, cloud microphysics, boundary layer dynamics, and even wildfire behavior.

KaRVIR hopes to deliver unprecedented high-resolution measurements of cloud microphysics, turbulence, and three-dimensional air motions, providing essential insights into the initiation of rainfall and acting as a standard for cloud-resolving weather models.
Its estimated capability to identify particles ranging from fine ash to substantial cloud formations at millimeter wavelengths could greatly improve wildfire monitoring, forecasting, and predictions regarding long-range smoke transport, enhancing air quality preparedness for remote communities.
In addition to advancing scientific knowledge, KaRVIR aims to improve public safety by facilitating quicker and more precise severe weather alerts and disaster response. It also aims to educate and train the next generation of scientists and engineers through practical research and educational opportunities.
The KaRVIR initiative brings together faculty specialists from the Gallogly College of Engineering and the College of Atmospheric and Geographic Sciences, along with proficient radar engineers from the ARRC.
