Dr. Jay McDaniel, ECE Assistant Professor and member of the ARRC, has received a prestigious Faculty Early Career Development (CAREER) Program award from the National Science Foundation's Office of Polar Programs.

This five-year project will allow the McDaniel Microwave Group to develop a custom unmanned aerial vehicle, or UAV-based radar suite with sophisticated signal processing techniques to measure the depth and distribution of snow and ice to support actionable risk management strategies and socioeconomic resiliency from snow-related weather events.

Dr. Jorge Salazar Cerreno, ECE Associate Professor and member of the ARRC, was honored recently with the maximum distinction of Doctor Honoris Causa by the Universidad Antenor Orrego in Peru.

In a ceremony hosted by the ARRC on November 9, graduate student Rachael Cross was the recipient of the 2022 Weathernews Inc. Scholarship.  

The $5000 award, established in 2017 to enhance advanced research and development of radar technology, is presented annually to an outstanding ARRC student studying weather radar, observations of the atmosphere, data analysis, and implementation.   

Pictured presenting the award to Rachel are (l. to r.) Michihiro Teshiba, Weathernews Inc., Berrien Moore, Dean of the College of Atmospheric and Geographic Sciences, and Bob Palmer, Executive Director of the ARRC.

A team of scientists from the ARRC, the School of Meteorology, the Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO), and NSSL deployed multiple radar systems to collect data from the cold front that passed through the OKC metro area on Friday, November 4. 

 The RaXPol radar collected polarimetric data from 1601 - 1934 UTC, including several RHI scans approximately normal to the cold front and several PPI volume scans as well. According to the Norman Mesonet station, which was in view to the SW, the cold front’s passage over the deployment site occurred at approximately 1730 UTC. The teams felt the temperature drop 20-25 °F over an approximate time of 5 - 10 seconds following the wind shift. Simultaneous data was collected with the research WSR-88D (KOUN) and the mobile NOAA X-POL (NOXP) polarimetric radars. 

 The team was led by Dr. David Schvartzman, who coordinated with Drs. Howie Bluestein, David Bodine, and Valery Melnikov, to conduct the multi-frequency radar observations of the cold front and surrounding convective cells. Several students from the School of Meteorology, School of Electrical and Computer Engineering, and others affiliated with the ARRC, participated in the data collection experiment. The data will be used to conduct a dual-frequency / dual-polarization analysis with ARRC, SoM, CIWRO, and NSSL investigators collaborating to bring needed expertise together

Fantastic fall weather only added to the fun for ARRC members participating in the First Annual Hiking Trip last Saturday in the Wichita Mountains near Lawton. As beautiful as the weather was, the camaraderie was even better. “Clearing our minds in nature makes our research even better!” said ARRC Executive Director Bob Palmer.
