Microwave Refractive Index Structure Function Profiles (Cn2) Measured from a Small Aircraft

reportActive / Technical Report | Accession Number: ADA184343 | Open PDF

Abstract:

Measurements of the microwave refractive index structure function Cn2 obtained with a microwave refractometer on a small aircraft are presented. Thin layers 300 m of highly enhanced Cn2 were observed on several flights, usually associated with an inversion. Results from two refractometers about 4 m apart are shown for several flights. The double measurements are discussed from the point of view of the validity of the measurements themselves. Keywords include Refractive index structure function, Refractometers, and Atmospheric refraction.
