scqc¶

Derives quality control (QC) parameters from waveforms.

Description¶

scqc determines waveform quality control (QC) parameters of data streams. The output parameters are time averaged in terms of waveform quality messages. In regular intervals report messages are sent containing the short term average representation of the specific QC parameter for a given time span. Alarm messages are generated if the short term average (e.g. 90 s) of a QC parameter differs from the long term average (e.g. 3600 s) by more than a defined threshold. To avoid an excessive load, QC messages are sent distributed over time. Storing QC parameters into the database should be avoided by configuring, e.g., plugins.default.archive.interval as otherwise the database grows quickly.

The QC parameters can be interactively observed using scqcv or scmm.

Technology¶

scqc uses plugins to compute the waveform quality control (QC) parameters. The plugins can be found in @DATADIR@/plugins/qc. They are loaded by default or selected by configuration setup.

QC parameters¶

../_images/times.png — Times describing the data records, e.g., for calculating delay or latency. $t_{now}$ may be measured differently depending on the QC parameter.¶

Times describing the data records, e.g., for calculating delay or latency. $t_{now}$ may be measured differently depending on the QC parameter.¶

The following QC parameters are determined when the corresponding plugin is loaded:

availability [%]

Plugin: qcplugin_availability

Description: Availability of data in the configured time span.

delay [s]

Plugin: qcplugin_delay

Description: Time difference between current time, $t_{now}$ , and time of the last record in the SeisComP system (see Figure):

$delay = t_{now} - t_{2}.$

Note

Current time is measured during reception of a record and updated in the report intervals configured for delay.

gaps (count [counts], interval [s], length [s])

Plugin: qcplugin_gap

Description: In case of a data gap between two consecutive records this parameter delivers the gap interval time (interval), the mean length of the gaps (length) and the number of the gaps (count) over the configured time interval.

Hint

gaps interval = 0 for gaps count = 1 but gaps interval > 0 for gaps count > 1. This may be important when evaluating the intervals.

latency [s]

Plugin: qcplugin_latency

Description: Time difference between current time, $t_{now}$ , and arrival time of the last record (see Figure):

$latency = t_{now} - t_{arr}.$

Note

Current time is measured during reception of a record and updated in the report intervals configured for latency.

offset [counts]

Plugin: qcplugin_offset

Description: Average value of all samples of a record.

outage [time string]

Plugin: qcplugin_outage

Description: Delivers the start and the end time of a data outage (gap).

overlaps (count [counts], interval [s], length [s])

Plugin: qcplugin_overlap

Description: In case of overlaps between two consecutive records this parameter delivers the overlaps interval time (interval), the mean length (length) of the overlaps and the number of the overlaps (count) over the configured time interval.

Hint

overlaps interval = 0 for overlaps count = 1 but overlaps interval > 0 for overlaps count > 1. This may be important when evaluating the intervals.

rms [counts]

Plugin: qcplugin_rms

Description: Offset corrected root mean square (RMS) value of a record.

spikes (count [counts], interval [s], amplitude [counts])

Plugin: qcplugin_spike

Description: In case of the occurrence of a spike in a record this parameter delivers the time interval between consecutive spikes (interval), the mean amplitude of the spike (amplitude) and the number of the spikes (count) over the configured time interval. Internally a list of spikes is stored (spike time, spike amplitude); the spike finder algorithm is still preliminary.

Hint

spikes interval = 0 for spikes count = 1 but spikes interval > 0 for spikes count > 1. This may be important when evaluating the intervals.

timing [%]

Plugin: qcplugin_timing

Description: miniSEED record timing quality (0 - 100 %) as written into the miniSEED records by the digitizer.

Setup¶

The configuration can be adjusted in the module configuration (scqc.cfg).

Select the streams for which to compute the QC parameters. Be default, only streams defined global bindings are considered:
- use3Components: Select to consider the 3 components related to the stream defined by global bingings. Reguires to select useConfiguredStreams.
- streamMask: Freely choose any available stream to compute the QC parameters for. This requires to unselect useConfiguredStreams. Regular expressions may be used, e.g.:
  - Consider BHZ streams from all networks, stations and locations:
    streamMask = ""(.+)\.(.+)\.(.*)\.(BHZ)$"
  - Consider any component from BH, LH and HH streams:
    streamMask = "(.+)\.(.+)\.(.*)\.((BH)|(LH)|(HH))?$"
Load the QC and other plugins, e.g. for data acquisition. The QC plugins loaded by default are qcplugin_availability, qcplugin_delay, qcplugin_gap, qcplugin_latency, qcplugin_offset, qcplugin_outage, qcplugin_overlap, qcplugin_rms, qcplugin_spike and qcplugin_timing.

Adjust plugins for setting plugins explicitly and to exclude the other ones, e.g.
```
plugins = qcplugin_availability, qcplugin_spike
```
Further RecordStream plugins for reading data may be considered.
Configure the plugin parameters: Each plugin considers specific parameters which can be configured separately or the default section.
