Welcome from the Executive DirectorWelcome to the Advanced Radar Research Center (ARRC) at the University of Oklahoma! The ARRC is approaching its 10-year anniversary, and in that time has grown from a small group of energetic faculty and students into the largest academic radar program in the nation with well over 100 members. We focus on interdisciplinary education, leveraging a nationally ranked meteorology program and aggressively growing engineering departments. Our School of Electrical and Computer Engineering, for example, has moved up 25 spots in national rankings in just the last year, largely due to a significant growth in radar and applied electromagnetics. The ARRC recently moved into the state-of-the-art Radar Innovations Laboratory – a 35,000-sqft “working laboratory” dedicated to innovations in radar technology and science. With the complete support of the university administration, the ARRC is poised to become the “go to” place for all things radar! -- Bob Palmer
ARRC Scientists Deploy Radars to Study Hurricane Joaquin
A team of scientists from the University of Oklahoma's (OU's) Advanced Radar Research Center (ARRC) is deploying two mobile weather radars from the ARRC in advance of hurricane Joaquin. Hurricane Joaquin has already reached major storm status (Cat 3) and is expected to strengthen further before weakening slightly by landfall. Given that inland flooding is a major cause for loss of life during landfalling hurricanes, the ARRC scientists will focus on studying "Rossby Vortex Waves", an atmospheric wave phenomena that generates rain bands that spin outward from the eyewall region into the inner core of the hurricane. It is believed that these rain bands contribute significantly to the flooding rains that accompany many landfalling hurricanes. The team, led by Dr. Michael Biggerstaff from OU's School of Meteorology, have deployed mobile radars in past hurricanes including Isabel in 2003, Francis in 2004, Ike in 2008, Irene in 2011 and Isaac in 2012. The two radars being sent to study Joaquin are the ARRC's rapid-scanning dual-polarimetrric X-band radar (RaXPOL) and the C-band dual-polarimetric Shared Mobile Atmospheric Research and Teaching (SMART) radar. Both radars have been used to study tornadic storms, lightning, nocturnal heavy rains and hurricanes. The OU group is part of the Digital Hurricane Consortium, a collection of university, private sector and federal laboratories that coordinate research observing system deployments in advance of landfalling hurricanes. This year the SMART radar data will be transmitted back in near real-time to a server at OU and made available to the National Oceanic and Atmospheric Administration (NOAA) for dissemination in a preliminary test of the Coastal Recovery Act which will support future deployments to aid operational weather forecasts and warnings during landfalling hurricanes in the US.Posted on Thursday Oct 01, 2015 10:46 am CDT
Research Grant Paves Way for Weather Drone Studies in Oklahoma

OU and NSSL Research Scientists and Professor received NASA Group Achievement Award
Research Scientist Dr. Pierre-Emmanuel Kirstetter (ARRC/NSSL), along with Dr. Yang Hong (CEES/ARRC) and Dr. Jonathan J. Gourley (NSSL) are members of the Global Precipitation Measurement (GPM) Post-Launch Team recently selected for a NASA Agency Group Achievement Award with a citation “For exceeding all expectations for GPM operations, data processing, algorithm performance, science impact, and education and public outreach within one year after launch”. GPM is an international network of satellites that provides the next-generation observations of rain and snow across the entire globe. NASA's most prestigious honor awards are approved by the Administrator and presented to a number of carefully selected individuals who have distinguished themselves by making outstanding contributions to the Agency's mission. These NASA awards highlight the contribution of outstanding hydrometeorological research conducted on the Norman campus to advance our understanding of Earth's water and energy cycle, improve forecasting of extreme events such as floods, and extend current capabilities in using accurate and timely observations of precipitation to directly benefit society.Posted on Monday Jul 27, 2015 05:21 pm CDT
