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.
Zac Flamig (ARRC/SoM/HyDROS Lab) was recently involved in hydrology capacity building in Namibia and Rwanda. Invited by the Namibia Department of Hydrology, Zac spent a week in that country discussing the requirements for establishing a hydrologic model for the prediction of flooding on the Okavango River. The desire is to set up the OU Coupled Routing and Excess Storage (CREST) hydrologic model to provide prediction of future flooding events. Zac then conducted a weeklong CREST training workshop in Kigali, Rwanda for the Integrated Water Resources Department. The workshop involved approximately 20 government hydrologists and meteorologists. Zac was supported by the joint efforts of NASA and the U.S. Agency for International Development (USAID), and the National Science Foundation's Partner's for International Research and Education (PIRE) program.
Congratulations to Vivek Mahale, ARRC and SoM student, who recently won the 2013 Best Student Paper Award for the 16th conference of the AMS Committee on Aviation, Range, and Aerospace Meteorology (ARAM). Both Vivek's oral conference presentation and written paper, "The Microphysics of the 14 June 2011 Norman, Oklahoma, Downburst from Dual-polarization and Dual-Doppler Radar Measurements", were commended by the judges. In addition to an AMS certificate of achievement and monetary prize, the award will be announced in an upcoming issue of BAMS. Drs. Guifu Zhang and Ming Xue are Vivek's advisors and co-authors of the paper.
ARRC and ECE student Lei Lei was notified that her conference presentation, "A Comparison of Planar and Cylindrical Configurations of Polarimetric Phased Array Radar for Weather Observation", had been recognized for a student award at the recently held AMS Weather Analysis and Forecasting Symposium. Lei will receive a certificate and monetary award for her achievement. Congratulations!
Drs. Yang Hong, Pierre Kirstetter, Qing Cao (ARRC/CEES) and Dr. Jonathan Gourley (NOAA/NSSL) have been selected by the NASA Global Precipitation Measurement (GPM) mission as Science Team Members. As PI, Science PI or Co-PI, Hong and his team's three proposals have also been selected by the NASA Headquarter Precipitation Science Program for the 2013-2016 period. GPM is an international network of satellites that provide the next-generation global observations of rain and snow. The GPM concept centers on the deployment of a "Core" satellite carrying an advanced radar/radiometer system to measure precipitation from space and serve as a reference standard to unify precipitation measurements from a constellation of research and operational satellites. Through improved measurements of precipitation globally, the GPM mission will help to advance our understanding of Earth's water and energy cycle, improve forecasting of extreme events that cause natural hazards and disasters, and extend current capabilities in using accurate and timely information of precipitation to directly benefit society. The GPM Core Observatory is scheduled to launch in early 2014.
ARRC student Yunsung Hwang recently received notification that he had been selected as a winner of the 11th Conference on Artificial and Computational Intelligence and its Applications to the Environmental Sciences Student Competition. The competition took place during the AMS annual meeting in Austin, Texas. Yunsung received the award for his abstract "Novel Gust Front Detection with Polarimetric WSR-88D Using Neuro-fuzzy System. Congratulations Yunsung!
