pyart.correct.cloud_threshold(data, n_avg=1.0, nffts=None)[source]#

Calculates the noise floor from a cloud threshold.

Parameters:

  • data (array) – Numpy array

  • n_avg (float) – Number of points to average over

  • nffts (int) – Number of heights to iterate over. If None will use the size of data.

Returns:

result (numpy scalar float) – Returns the noise floor value for each time sample.
