pyart.correct.calc_cloud_mask#

pyart.correct.calc_cloud_mask(radar, field, height=None, noise_threshold=-45.0, threshold_offset=5.0, counts_threshold=12)[source]#

Primary function for calculating the cloud mask.

Parameters:

  • radar (Radar) – Py-ART Radar object.

  • field (string) – Reflectivity field name to calculate.

  • height (string) – Height name to use for calculations.

  • noise_threshold (float) – Threshold value used for noise detection. Greater than this value.

  • threshold_offset (float) – Threshold offset value used for noise detection

  • counts_threshold (int) – Threshold of counts used to determine mask. Greater than or equal to this value.

Returns:

radar (Radar) – Returns an updated Radar object with cloud mask fields.
