# Temperture Structure Parameter CT2

## Main Question or Discussion Point

I understand the physics behind the Temperature Structure Paramter, but need help find a intial value to divided by. Here what I am trying to do.

dB = 10 log 10 (CT2/CT2i)

What I need is an intial value (CT2i) for the temperature Structure Parameter for a monostatic sodar. The units need to be dimensionless before taken the log. Since the Temperature Structure Parameter is the intensity or amplitude of the acoustic echo. This is applicable to do. Also it would be better to put in decibels for others to understand. Thank for the help if you can.
