91AV Polarimetric Doppler Weather Radar

Description:

In 2012, 91AV 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 (press release). ÌýIn 2015, was awarded the winning bid to manufacture and erect 91AV's weather radar.

The 91AV weather radar is a scanning polarimetric Doppler radar operating at S-band with a beam width of 0.95°. ÌýIn addition to being an education and research tool for the Department of Atmospheric Science, the radar will fill a low-level NEXRAD coverage gap over northeast Louisiana and southeast Arkansas (see before and after). ÌýThe radar data will be available to the National Weather Service to help serve their mission of protecting life and property in this region, which is important considering the ArkLaMiss is prone to severe weather (see climatology of tornado formation within 100-km of the 91AV radar location).

91AV is the only primarily undergraduate institution in the United States with a S-band polarimetric Doppler weather radar. ÌýOur students receive hands-on instruction at the undergraduate level on radar operation, in addition to advanced radar analysis and interpretation techniques. ÌýThis uniquely positions our graduates for jobs that require radar operation and/or analysis skill.

Radar Groundbreaking:

Officials from GOSHEP and 91AV, including faculty and students, officially broke ground on the weather radar on May 6, 2015 (). Ìý for more photos from the groundbreaking.

Current Status (9/18/17):

The 91AV polarimetric S-band Doppler weather radar is operational with base products available onÌýour . ÌýThe radar is in use by the region's emergency managers and the National Weather Service offices in Shreveport, LA and Jackson, MS.
