Research Aviation Facility Bulletins

The RAF Bulletin series is intended to guide scientists in making effective use of NCAR aircraft. Some of the topics presented here deserve more space than is available. However, we have endeavored to make the material useful to those having little or no experience in the use of an aircraft as an observing system. For historical versions for RAF Bulletins (including many that are not listed here) please visit the RAF Collection at the NCAR Archives.
