MOBNET is a pool of seismic stations installed temporarily in tectonically different regions in\u00a0the frame of\u00a0collaborative seismic experiments. The pool has been developed step by step since 1998 and it consisted of 65 portable units at the end of 2016. Pairs of seismometer-data acquisition systems create each of the mobile units. About half of seismometers of the pool are the short period Lennartz Le-3D (32 pieces), the rest are\u00a0tree-component broad-band seismometers \u2013 STS2 and Guralp (CMG-3T, CMG-3ESP, CMG-40T). GAIA data acquisition systems work mostly in offline regime, reporting daily the state-of-health for all of the stations via \u2018sms\u2019. Online data transmission is also possible. Previously, the stations of the pool have been involved, e.g., in the RETREAT (N. Apennines), LAPNET (N. Finland), PASSEQ (central Europe), MOSAIC, and BOHEMA (Bohemian Massif) passive seismic experiments. Currently, twenty broad-band stations are involved in the large collaborative\u00a0European\u00a0project AlpArray<\/a>\u00a0and have been involved in the AlpArray complementary passive experiment EASI.<\/p>\n
