correction of the system offset and smoothing using two window

Parameters:

  • radar (Radar) – Radar object for which to determine the system phase.

  • ind_rmin, ind_rmax (int) – Min and max range index where to look for continuous precipitation

  • min_rcons (int) – The minimum number of consecutive gates to consider it a rain cell.

  • zmin, zmax (float) – Minimum and maximum reflectivity to consider it a rain cell

  • swind_len (int) – Length of the short moving window used to smooth

  • smin_valid (int) – Minimum number of valid bins to consider the short window smooth data valid

  • lwind_len (int) – Length of the long moving window used to smooth

  • lmin_valid (int) – Minimum number of valid bins to consider the long window smooth data valid

  • zthr (float) – reflectivity value above which the short window is used

  • psidp_field (str) – Field name within the radar object which represent the differential phase shift. A value of None will use the default field name as defined in the Py-ART configuration file.

  • refl_field (str) – Field name within the radar object which represent the reflectivity. A value of None will use the default field name as defined in the Py-ART configuration file.

  • phidp_field (str) – Field name within the radar object which represent the corrected differential phase shift. A value of None will use the default field name as defined in the Py-ART configuration file.

Returns:

phidp_dict (dict) – The corrected phidp field
