pyart.correct.det_sys_phase_ray(radar, ind_rmin=10, ind_rmax=500, min_rcons=11, zmin=20.0, zmax=40.0, phidp_field=None, refl_field=None)[source]#

Public method Alternative determination of the system phase. Assumes that the valid gates of phidp are only precipitation. A system phase value is found for each ray.

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) – The minimum and maximum reflectivity to consider the radar bin suitable precipitation
phidp_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.

Returns:

phidp0_dict (dict) – Estimate of the system phase at each ray and metadata
first_gates_dict (dict) – The first gate where PhiDP is valid and metadata
