GRIB:

Acceptable proportion of signal returns as a percentage by moored acoustic doppler current profiler. Percent-good data indicate what fraction of data passed a variety of criteria. Rejection criteria include low correlation, large error velocity and fish detection (false target threshold). Default thresholds differ for each ADCP; each threshold has an associated command.

AMIP:

GRIB:

The phrase "proportion_of_acceptable_signal_returns" means the fraction of a collection (ensemble) of returned signal transmissions that have passed a set of automatic quality control criteria. For an ADCP (acoustic doppler current profiler) the rejection criteria include low correlation, large error velocity and fish detection. The dimensionless proportion is often but not exclusively expressed as a percentage when it is referred to as "percent good".
