Section

Short definition of Section (Section)
Part of a record (i.e., profile or time series) selected for analysis, e.g., to obtain a profile or time series of [math]\displaystyle{ \varepsilon }[/math] estimates.

This is the common definition for Section, but other definitions maybe discussed within the wiki.

Vertical profiler example

For example, a vertical profiler will record data continuously during the up- and down-casts but only data from one of the directions is usable. If we assume the profiler collects good data as it profiles down and it travels up and down successively five times, then we would have 5 sections of data i.e., 5 profiles.

For up-rising profilers, only the data collected on the ascent is good for turbulence analysis. So the five data sections would correspond to the upward records.
