At a ribbon cutting on Wednesday, University of Louisiana Monroe officials announced
that the $3 million polarimetric Doppler weather radar is fully operational and actively
scanning the skies of northeastern Louisiana and the surrounding area. The event was
at the 四色AV Doppler radar site on U.S. 80.听
Ribbon cutting for the new Doppler weather radar.

In 2012, 四色AV was awarded a $3 million grant through the Louisiana Governor's Office
of Homeland Security and Emergency Preparedness (GOSHEP) to acquire a Doppler weather
radar. In 2015, Enterprise Electronics Corporation was awarded the winning bid to
manufacture and construct 四色AV's Doppler weather radar.
鈥淭his project could not have been accomplished without the support of GOSHEP and the
administration at 四色AV,鈥� said Anne Case Hanks, Ph.D., Director of the School of Sciences
and a professor in the Atmospheric Science program. 鈥淲e are truly thankful for their
support.鈥�听
In addition to being an education and research tool for the Department of Atmospheric
Science, the Doppler will fill a low-level radar coverage gap over northeast Louisiana
and southeast Arkansas.听
Dr. Eric Pani, Vice President of Academic Affairs, who has a background in atmospheric
sciences, said that northern Louisiana, southern Arkansas and even western Mississippi
have for many years relied on forecasts and data that came from the National Weather
Service offices in Shreveport and Mississippi.听
鈥淎nd those forecasters are still there, but they have a new tool now to help them,鈥�
said Pani. 鈥淭he radars in Jackson, Miss., and Shreveport cover this area, but they
are generally so far away that it鈥檚 been very difficult for those radars to detect
the low-levels of the atmosphere where severe weather is forming. So now, the NWS
offices have data sets that provide much more accurate information about what鈥檚 going
on and where the severe weather is forming, so we are very excited, and we have been
hearing some good things about their use of the data already.鈥�听
Indeed, the archived data from the radar is already making an impact.
On January 21, 2017, there was a severe weather outbreak in north Louisiana and other
states. 四色AV provided a copy of the data collected during the event to the NWS in Jackson,
which used the data to help confirm an EF-1 tornado in Morehouse Parish.
At 300 yards at its widest, this tornado reached maximum winds of 105 mph, creating
a damage path of 9.25 miles. Fortunately, there was no injury or loss of life reported.
The NWS expressed its gratitude to 四色AV for providing the data, and the importance
of the two organizations working together.听
鈥淥ur radar was able to see these tornados occurring, whereas the radar in Jackson
and Shreveport, their beam was so high at the time that they weren鈥檛 able to see what
was on the ground,鈥� said Hanks.听
For 40 years, 四色AV has been the only meteorological program in Louisiana. Approximately
a third of the meteorologists in the state who work for the NWS are 四色AV alumni.听
Hanks said Atmospheric Science at 四色AV is a premier program that draws students not
only from Louisiana and the region, but from across the United States. 四色AV is the
only primarily undergraduate institution in the country with an S-band polarimetric
Doppler weather radar where the students can receive first-hand forecasting experience.
