Abstract

Two Atmospheric Boundary Layer (ABL) models, the Kukaharets/Tsvang and the Kaimal models are used to obtain Cn² profiles during daytime conditions for comparison with balloon-borne thermosonde measurements. Path averaged Cn2 measurements obtained on a 14 meter tower are used as inputs to the models. Values of ro2(coherence length) and Oo (isoplanatic angle) are calculated by integration of model expressions for Cn2 as a function of altitude. The VanZandt mode is used to obtain ro and go contributions from above the ABL. These are compared to values obtained by integration over the thermosonde Cn2 height profiles. Comparisons are also made to isoplanometer and MTF device measurements made near the ground.
