NOAA today announced that it is exercising a contract option with King Aerospace Inc. of Addison, Texas, for the construction, integration, and system testing for a tail Doppler radar to be installed on the agency’s Gulfstream-IV hurricane surveillance aircraft. The option is valued at $3.1 million.

“By installing the tail Doppler radar on the G-IV jet, NOAA will be taking a first step toward improving intensity forecasts,” said Rear Admiral Samuel P. De Bow Jr., director of NOAA’s Office of Marine and Aviation Operations and the NOAA Commissioned Officer Corps. “This ultimately will help forecasters save lives and property during hurricanes.”

With the TDR system, the G-IV will be able to acquire three-dimensional hurricane core wind field data. The raw radar data will be processed onboard the aircraft through quality-control software being developed by NOAA’s Hurricane Research Division in Miami, Fla. This quality-controlled data will then go into the new Hurricane Weather Research and Forecasting model being developed by the National Weather Service’s Environmental Modeling Center in Suitland, Md. The model will be used by NOAA’s National Hurricane Center to aid forecasters in hurricane intensity forecasts.

NOAA expects the system to reach full operational capability by the beginning of the 2009 hurricane season on June 1.

As part of the NOAA aircraft fleet, the G-IV is operated, managed and maintained by the Aircraft Operations Center of NOAA’s Office of Marine and Aviation Operations, located at MacDill Air Force Base in Tampa, Fla.

In 2007 NOAA, an agency of the U.S. Commerce Department, celebrates 200 years of science and service to the nation. From the establishment of the Survey of the Coast in 1807 by Thomas Jefferson to the formation of the Weather Bureau and the Bureau of Commercial Fisheries in the 1870s, much of America's scientific heritage is rooted in NOAA.

NOAA is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of our nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 60 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.
