WAVEFRONT COHERENCE TIME (τ0) TEMPORAL EVOLUTION
Temporal evolution of the wavefront coherence time integrated in different vertical slabs between the sunset and the sunrise:-
TOTAL WAVEFRONT COHERENCE TIME (τ0,TOT) - [dome-20000]m
BOUNDARY LAYER WAVEFRONT COHERENCE TIME (τ0,BL) - [dome-600]m
FREE ATMOSPHERE WAVEFRONT COHERENCE TIME (τ0,FA) - [600-20000]m
On the x-axis is time in UT (bottom), in MST (top). Mountain Standard Time MST=UT-7. Data points frequency is 2 minutes. Data points are re-sampled at a frequency of 20 minutes after a 1-hour moving average. The error bars (black line) are the sigma over the 20 minutes sampling, computed before the moving average.
