AB: The SZGRF operates a regional data center comprising broadband waveform data of the Graefenberg array (GRF) and the German Regional Seismological Network (GRSN). The continuous archive reaches back to 1976 (for GRF) and 1991 (for GRSN) and is completely automatically accessible via WWW and AutoDRM (details see http:www.szgrf.bgr.de) . The total number of permanently archived stations is currently 42. The majority of the stations is transmitted in near-realtime, others are copied with a delay between 20 min and 1 day. The data quality is assured by automatic check procedures and by a daily manual event analysis. Currently, the archiving system is modernized from a semi-automatic procedure to a fully automated system based on a mysql database and self developed archiving tools (Python scripts). The station sites are equipped with STS-2 seismometers and 24bit digitzers. The instruments are installed in vaults keeping stable temperature. The GRF and some of the GRSN sites are additionally equipped with pressure-tight housings to reduce the influence of air pressure variations on the recordings.
