Beginning November 12th, 2019, the KOAX WSR-88D operated by NOAA`s National Weather Service in Omaha/Valley, Nebraska went out of service for an important upgrade. Technicians refurbished and replaced the pedestal, one of the most critical components of the radar, which is necessary for antenna rotation and positioning to capture data in all directions. The components are extremely heavy and required the radome to be removed by crane and replaced when the work was completed (see below).

Pedestal Hoisting Pedestal

The radar and pedestal were designed to last 25 years, and this radar has exceeded its lifespan. This activity is necessary to keep the radar functioning for another 20 years or more.

The pedestal refurbishment is the third major project of the NEXRAD Service Life Extension Program, a series of upgrades that will keep our nation`s radars viable into the 2030s. NOAA`s National Weather Service, the United States Air Force, and the Federal Aviation Administration are investing $150 million in the eight year program. The first project was the installation of the new signal processor and the second project was the refurbishment of the transmitter. The fourth project will be the refurbishment of the equipment shelters. The Service Life Extension Program will be complete in 2023.

During the downtime, adjacent radars will be available. These include KFSD in Sioux Falls, KDMX in Des Moines, KEAX in Pleasant Hill, KTWX near Topeka, KUEX near Hastings, and KLNX near North Platte.

The KOAX WSR-88D is part of a network of 159 operational radars. The Radar Operations Center in Norman, Oklahoma provides lifecycle management and support for all WSR-88Ds.
