“…( 97) with Hilo ðdz ¼ 200 mÞ-C 2 n ðhÞ using that wind speed profile supplied by Mr. Quatresooz and Professor Oestges. 40 The two profiles are in better agreement in the 12-km and upper region but deviate some in the lower atmospheric region. However, both figures are in reasonable agreement with the data overall.…”

“…Substituting Eqs. (39) and (40) into Eq. ( 36) yields E Q -T A R G E T ; t e m p : i n t r a l i n k -; e 0 4 1 ; 1 1 4 ; 1 2 0 The current threshold that minimizes the BER given in Eq.…”

“…This requires tracked/tilt-corrected and untracked beam wander models. 40 The key to these models is two sets of nondimensional beam parameters-one set at the transmitter and a second set at the receiver at distance R. For collimated transmitter, we have E Q -T A R G E T ; t e m p : i n t r a l i n k -; e 1 0 7 ; 1 1 4 ; 3 6 7…”

“…Figure 20 shows a year-long average of the refractive index structure parameter profile versus altitude estimates as a function of the re-interpolation distance dz (estimate’s vertical spacing) generated by Quatresooz et al., using the high-density profiles from the University of Wyoming (UWYO) Atmospheric Science Radiosonde Archive 40 . This set of data profiles is for Hilo, Hawaii.…”
