- pyart.util.image_mute_radar(radar, field, mute_field, mute_threshold, field_threshold=None)[source]#
This function will split a field based on thresholds from another field.
Specifically, it was designed to separate areas of reflectivity where the correlation coefficient is less than a certain threshold to discern melting precipitation.
radar (Radar) – Radar instance which provides the fields for muting.
field (str) – Name of field to image mute.
mute_field (str) – Name of field to image mute by.
mute_threshold (float) – Threshold value to mute by.
field_threshold (float) – Additional threshold to mask.
radar (Radar) – Radar object with 2 new fields from input field, one muted and one not muted.
