Abstract

Intercomparison of C_n² measurements using a stellar scintillometer, UHF radar and ballon-borne microthermal probes(thermosonde) demonstrate near identical results. The radar provides data at improved altitude resolution (≈1 km) with a long time base. The thermosonde provides even higher altitude resolution (≈ 20 m) but over a short time base The results of the intercomparison measurements conducted in 1981 at Westford, MA are presented. A comparison of the coherence length and isoplanatic angle are shown using the different altitude resolution data.
