Data quality
The continuous seismic waveform data from the Virtual European
Broadband Seismograph Network (VEBSN) are monitored at ORFEUS
Data Center (ODC) in various ways to ensure a high quality of
waveform data and metadata. The following monitors are in place:
-
Power Spectral Density (PSD) versus time:
this near real-time monitor
displays the PSD of the background noise as function of time,
for selected
frequencies. Also the energy in two frequency bands is shown,
as well as the lowest PSD level at each frequency.
Find here
the details of our procedure.
To view the PSD
per network, go to the PSD-interface.
- PQLX:
this near real-time monitor
displays the distribution of the PSD through a
Probability Density Function (PDF).
- Magnitude: histograms for magnitude
(Mb, MS)
differences between station magnitude
and VEBSN magnitude.
- Time residuals: look here
for the time residuals distribution for
each station.
For further information please contact
or any other ORFEUS staff member.
