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. The Research Aviation Facility (RAF) provides airborne instrumentation for acquiring data in support of various facets of cloud microphysical research. These instruments measure the amount of cloud water, particle concentration, shapes, and sizes. Instrument configurations vary according to aircraft and scientific objective and scientists who use data from these instruments should be aware of the measurement limitations imposed in general by the capabilities of the instruments and by particular mounting configurations when applicable.
