September 22 2017:

Reimported all Z3 stations from RESIF, France.

June 7 2017:

We imported a complete new version of the GFZ Z3 stations we got from Peter Evans by Mail. The changes include:

- A118A (Schrozberg) has been closed.

- A118B continues from A118A in almost the same location.

- There are some tiny changes in gains for some stations
  (A111A, A112A, A114A, A115A at least)
  compared to the last inventory file that we sent you (I think)
  on Nov 23  2016.

May 10 2017

We have set the end date of the closed station Z3.A060A to 2017-02-16 10:00 and added the new station Z3.A060B .

March 1 2017:

Changed the station.archive element to SED for the following stations: 122A, A123A, A124A, A126A, A127A, A128A A038A A140A, A141A, A143A, A144A, A145A, A146A, A147A, A147B, A148A, A148B

Updated station A334A with a new epoch because the sensor was rotated.

Data availability

Last update April 2018

Data quality check for single earthquakes

Data quality report from for 35 earthquakes in 2016 and 2017, The data were downloaded from EIDA. All data were systematically checked for data completeness, gaps and overlaps within a 1–2 hour time window after the origin time.

Download here the complete report.

The table below summarizes the findings for all of the 35 earthquakes and all permanent and temporary stations.

Data completness check for 2016 data

Data completeness map (2016) of the AlpArray station from 1/1/16 to 01/01/2017. Data was downloaded from EIDA  using arclink protocol (last check January 2018).

Data availability is calculated over the period of time from the installation date (or from 01/01/2016 if installed before) to 01/01/2017 (or to the end of the station operation if before 01/01/2017).
The station list is the list sent by AASN manager in August 2017.

The overall data collection reaches ~85% of completness and 78% for Z3.

Download here the single network data completness plots (one plot per Network code) for the first year - 2016 (last check January 2018)

Download here the PPSD plots for all available stations (data for all 2016 and part of 2017).

 

Summary of the single network performance. Period analyzed: from 01/01/2016 to 01/01/2017

Data availability is calculated over the time period from the installation date (or from 01/01/2016 if installed before) to 01/01/2017 (or end of the station operation if before 01/01/2017). The station list is from August 2017.
