glidertools.optics.backscatter_dark_count
- glidertools.optics.backscatter_dark_count(bbp, depth, percentile=5)
Calculates an in situ dark count from the backscatter sensor.
The in situ dark count for the backscatter sensor is calculated from the user-defined percentile between 200 and 400m.
- Parameters:
bbp (numpy.ndarray or pandas.Series) – The total backscatter array after factory calibration in m-1.
depth (numpy.ndarray or pandas.Series) – The depth array in metres.
- Returns:
bbp – The total backscatter data corrected for the in situ dark value.
- Return type:
numpy.ndarray or pandas.Series
