Correlation magnitude of acoustic signal returns in counts from the water body by moored acoustic doppler current profiler. Correlation is a measure of data quality, and its output is scaled in units such that the expected correlation (given high signal/noise ratio, S/N) is 128.

GRIB:

The "beam_consistency_indicator" is the degree to which the magnitudes of a collection (ensemble) of acoustic signals from multiple underwater acoustic transceivers relate to each other. It is used as a data quality assessment parameter in ADCP (acoustic doppler current profiler) instruments and is frequently referred to as correlation magnitude. Convention is that the larger the value, the higher the signal to noise ratio and therefore the better the quality of the current vector measurements; the maximum value of the indicator is 128.
