pyart.correct.smooth_phidp_double_window(radar, ind_rmin=10, ind_rmax=500, min_rcons=11, zmin=20.0, zmax=40, swind_len=11, smin_valid=6, lwind_len=31, lmin_valid=16, zthr=40.0, psidp_field=None, refl_field=None, phidp_field=None)

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
