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 00 (isoplanatic angle) are calculated by integration of model expressions for Cn as a function of altitude. The VanZandt model is used to obtain ro and 00 conibutions from above the ABL. These are compared to values obtained by integration over the thermosonde Cn height profiles. Comparisons are also made to isoplanometer and MTF device measurements made near the ground.
