ARRC faculty members Drs. Robert Palmer, Sebastian Torres, Boon Leng Cheong and Caleb Fulton, and ARRC graduate student David Bodine, recently received funding from the National Science Foundation (NSF) for their research project titled "Understanding Polarimetric Radar Tornadic Debris Signatures Using Modeling, Simulations, and Field Measurements." One of the major objectives of the project will be a detailed investigation of debris scattering characteristics using radar cross-section (RCS) measurements, electromagnetic simulations, and polarimetric radar emulation/signal processing. These tools, along with extensive field studies, will have a major impact on the operational meteorological community through improved tornado detection and near real-time damage estimation, and will help estimate errors associated with debris centrifuging and debris-influenced radial velocity. Since flying debris causes most tornado fatalities, characterizing the debris field is vital for understanding and nowcasting the threats posed by tornadoes.
Four representatives of the Japan Society for the Promotion of Science (JSPS) visited the University of Oklahoma (OU) on September 11, 2013 to learn about key research initiatives and to promote awareness of their fellowship opportunities. JSPS highlighted fellowship programs for US researchers at all levels: Masters student, doctoral student, post-doctoral researcher, early, mid and senior career faculty and distinguished visitor. The JSPS visitors were able to tour the OU campus, including tours of the National Weather Center and Devon Energy Hall. Among the Departments and Centers visited were: Advanced Radar Research Center, Center for Analysis and Prediction of Storms, Center for Research Program Development and Enrichment, College of Arts and Sciences, College of Engineering, George Lynn Cross Research Center, Office of the Vice President for Research, School of Civil Engineering and Environmental Sciences, School of Electrical and Computer Engineering, School of Meteorology and the Sensing Laboratory.
The ARRC is currently looking to hire a post-doctoral research associate to work in the field of antennas. Interested candidates should send a cover letter and CV to Professor Guifu Zhang at email@example.com as soon a possible. Click here for additional information.
The deadly storms that ripped through Oklahoma in May were among the worst in recorded history, and were predicted a week early. The Oklahoma Educational Television Authority's (OETA) award winning documentary series Stateline looks into the creative mix of federal and state agencies and students working in the National Weather Center to further increase the warning time for people in the path of a storm.

The Discovering Engineering via Adventure in Science (DEVAS) camp, directed by ARRC/ECE faculty member Dr. Jessica Ruyle and ECE faculty member Dr. Chad Davis, was held recently in the Digital Lab at Devon Energy Hall. Twenty-eight girls attended the 1-day camp that featured an overview presentation of what electrical and computer engineer's do, followed by a hands-on activity where the girls teamed up to build a touchpad using aluminum foil, electrical tape, a breadboard, and an arduino. Volunteering at the camp were OU graduate students Alexander Moreno and Kathryn Kidson, and undergraduates Andrius Lietuvninkas and Brad Pirtle. Brad designed the touchpad project. Also volunteering was ARRC graduate student David Bodine, who demonstrated the ARRC's Atmospheric Imaging Radar to the group.
The ARRC is currently looking to hire a research scientist in radar signal processing to support and further strengthen its rapidly growing sponsored research in DoD- and weather-related radar. This person will support the research mission of the ARRC by providing technical expertise to existing research projects, by supporting the development of new strategic capabilities, and by developing their own funded research program.

Dr. Yang Hong, ARRC/CEES faculty member and head of the HyDROS Lab at the Nat'l Weather Center, has been selected as Chair-elect of the International Professionals for the Advancement of Chinese Earth Sciences (IPACES). Established in 1999, IPACES is a nonprofit organization whose mission is to advance earth sciences research and education in China, and to promote scientific collaborations between China and the rest of the world. Membership in IPACES is by invitation only with current members either tenured professors at U.S. universities or senior scientists at national laboratories. IPACES is among the largest Chinese overseas think tanks currently advising the Chinese government and universities on science, education, research and development. Congratulations Yang!
The ARRC is currently looking to hire a permanent analog RF engineer to support its rapidly growing sponsored research programs. This person will support the research mission of the ARRC through RF design and consulting services, maintenance of ARRC hardware infrastructure, technical mentoring and occasional supervision of ARRC students, and general engineering support to existing projects and new proposal efforts.

On March 14, 2013 the University of Oklahoma made history at the Kessler Atmospheric and Ecological Field Station (KAEFS) when it made the first flight of a research-class unmanned aerial vehicle under its FAA Certificate of Authorization (CoA). The SMARTSonde (Small Multifunction Autonomous Research and Teaching Sonde) team led by Prof. Phil Chilson (School of Meteorology/ARRC) used the aircraft to collect data in the lower atmosphere for the purpose of comparison and validation studies with ground based remote sensors such as radar, sodar, and lidar. OU is the only university in the state to hold a CoA and the flights represent the state of Oklahoma’s first integration of an unmanned aerial vehicle into the US National Airspace System for civilian applications. Several ARRC students (currently Tim Bonin and David Goines) have been key players in the SMARTSonde Project. Additionally, OU’s Center for Applied Research and Development (CARD) and Department of Aviation played a critical role in this enterprise. Special thanks to James Grimsley, Robert Huck, and Ken Carson for their help in acquiring the CoA and completing the first flights; Phil Gibson for his support as KAEFS Director; and Robin Torres for an excellent job as Pilot in Command.
ARRC Research Scientist Dr. Boon Leng Cheong was invited by the Meteorological Research Institute (MRI), a division of the Japan Meteorological Agency (JMA), to present the research effort of waveform design for solid-state weather radars. With the latest development from the ARRC, there is a potential to significantly increase the radar sensitivity using an improved waveform design. The enhancement can be achieved without any hardware changes, which is highly desirable for existing solid-state based weather radars as their transmit power is limited. While in Japan, Dr. Cheong also visited Toshiba, which developed the solid-state C-band weather radar at the JMA-MRI, to present and discuss the same research topic.
