Function Documentation

ComputePIA()

Lib.compute_pia.ComputePIA	(		pobject,
			param_name,
			keepPIA,
			reprocess_quality_flag,
			quality_control_mode )

Computes PIA based quality control.

A single scan object is sent to the ComputePIA function. The scans comprising a polar volume are sent to the same function individually.

Parameters

PolarVolumeCore	or PolarScanCore object
string	radar quantity name, defaults to DBZH
boolean	whether (True) or not (False) to keep the derived PIA parameter
boolean	reprocess_quality_flag
enum	quality_control_mode

ComputePIAscan()

Lib.compute_pia.ComputePIAscan	(		scan,
			param_name,
			keepPIA,
			reprocess_quality_flag,
			quality_control_mode )

Computes PIA based quality control.

A single scan object is sent to the ComputePIAscan function. The scans comprising a polar volume are sent to the same function individually.

Parameters

PolarScanCore	object
string	radar quantity name, defaults to DBZH
boolean	whether (True) or not (False) to keep the derived PIA parameter
boolean	reprocess_quality_flag
enum	quality_control_mode

main()

Lib.compute_pia.main

(
