Show moreThese bulletins describe the facilities, equipment, and services of the Research Aviation Facility, located at Jefferson County Airport in Broomfield, Colorado, and operated by the National Center for Atmospheric Research (NCAR) under the direction of the University Corporation for Atmospheric Research (UCAR). They are intended to guide scientists in making effective use of NCAR aircraft. NCAR presently operates three aircraft equipped with inertial navigation systems (INS) and a gust probe or a radome with pressure ports for air motion measurements. These aircraft can be instrumented to measure both mean horizontal wind and turbulent fluctuations of the three air velocity components. Show less
