- Abstract
- The future of Earth-to-space communications relies on the use of higher radio-frequencies and optical frequencies. For such frequencies, tropospheric turbulence starts to have deleterious effects, leading to important phase variations and amplitude scintillation. Those effects can be described thanks to the knowledge of vertical profiles of the refractive index structure parameter Cn2. In this work, two approaches relying on radiosonde measurements are presented to obtain radio-frequency and optical Cn2. Theoretical developments highlighting the contribution of humidity to radio-frequency scintillation are presented. This contribution is also illustrated with high resolution radiosonde data at Trappes (France) and Hilo (HI, USA). Obtained Cn2 profiles are in agreement with the literature and will be validated with measurements at millimeter waves in the future.
