Description
Summary:Infrasound detection bulletins have been estimated for the infrasound array at Panska Ves (50◦31’N 14◦34’E).\nThe signal arrivals in the frequency range 0.05-4 Hz were analysed. The bulletins are available from May 2014 to\nthe present.\nFrom mid-September to beginning of April, arrivals of signals of frequencies 0.1-0.4 Hz from the North West\ndominate. The azimuths of 290-340◦\ncorrespond to the position of microbarom source regions in the Northern\nAtlantic, south of Greenland (Landes, M. et al., 2012, J. Geophys. Res.). Signal elevations between 20◦\nand 40◦\nwere most frequent.\nIn summer (May-August), transient signals with highly variable azimuths of arrival frequently occur. Signal\narrivals were repeatedly observed from the North East and from the South East. However, a stable source\nanalogous to the microbarom source in Northern Atlantic was not found for signals arriving at Panska Ves array\nin summer.
