“…According to the power spectral density computations the noise on the vertical and the short period horizontal components typically meet the requirements, but this is not the case regarding the long period horizontal noise. These experiences are mostly consistent with the observations made during the AlpArray station deployments in Austria (Fuchs et al 2015), Italy (Govoni et al 2017), Switzerland (Molinari et al 2016) and the Czech Republic (Vecsey et al 2017).…”

In the last few decades dense large-scale seismic networks showed their importance in studying the structure of the lithosphere and the upper mantle. The better understanding of the Apennines-Alps-Carpathian-Dinarides system is the main target of the AlpArray European international initiative in which more than 50 institutes are involved. The core of AlpArray is the AlpArray Seismic Network (AASN). With its $ 600 broadband seismic stations ( $ 280 of which are temporary) the AASN is, so far, the largest passive seismic experiment in Europe. The MTA CSFK Geodetic and Geophysical Institute, as a Core Member of the AlpArray project, contributes to the AlpArray Seismic Network with its entire permanent network as well as with 11 temporary broadband seismic stations deployed in Western Hungary. Three additional station equipment were provided by the Swiss-AlpArray SINERGIA program. The average station distance together with the permanent stations is around 40 km in the area of interest. The temporary network has been installed between December 2015 and July 2016 and the planned operation period is 3 years. In this paper we describe the characteristics of the 29 permanent and temporary stations, introducing not only the equipment, but the location, housing and geological setting, as well. We present median power spectral density curves in order to characterise the noise conditions at each station.

“…6b). Although almost all our stations operate offline, the data completeness for the MOBNET stations in the AASN is similar to that for stations in the Austrian or Swiss parts of the AASN with an online data transmission (Fuchs et al, 2016;Molinari et al, 2016).…”

“…S1-S19 give the same detailed information for the remaining 19 MOBNET stations employed in the AlpArray-EASI network. Following the notation of Molinari et al (2016), we can characterize the locations as an urban free-field site and only exceptionally as a building site ( stored in the miniSEED data format which contributed to the AlpArray-EASI studies. After the end of the AlpArray-EASI field measurements in August 2015, 20 MOBNET stations were reinstalled in the Bohemian Massif as a part of the newly designed AASN (see Fig.…”

Abstract. This paper focuses on major issues related to the data reliability and network performance of 20 broadband (BB) stations of the Czech (CZ) MOBNET (MOBile NETwork) seismic pool within the AlpArray seismic experiments. Currently used high-resolution seismological applications require high-quality data recorded for a sufficiently long time interval at seismological observatories and during the entire time of operation of the temporary stations. In this paper we present new hardware and software tools we have been developing during the last two decades while analysing data from several international passive experiments. The new tools help to assure the high-quality standard of broadband seismic data and eliminate potential errors before supplying data to seismological centres. Special attention is paid to crucial issues like the detection of sensor misorientation, timing problems, interchange of record components and/or their polarity reversal, sensor mass centring, or anomalous channel amplitudes due to, for example, imperfect gain. Thorough data quality control should represent an integral constituent of seismic data recording, preprocessing, and archiving, especially for data from temporary stations in passive seismic experiments. Large international seismic experiments require enormous efforts from scientists from different countries and institutions to gather hundreds of stations to be deployed in the field during a limited time period. In this paper, we demonstrate the beneficial effects of the procedures we have developed for acquiring a reliable large set of high-quality data from each group participating in field experiments. The presented tools can be applied manually or automatically on data from any seismic network.

“…Molinari et al (2016), Fuchs et al (2016) and Govoni et al (2017). According to these standards, the allowed median value of the site noise-level for the noise should be 20 dB lower than the New High Noise Model (NHNM; Peterson, 1993) from 20 Hz up to 100 s, excluding the microseismic peak (5-20 s).…”
