Sažetak

At the `Regional IHY (International Heliophysical Year) Planning Meeting for the Balkan and Black Sea Region`, organized by the Solar Terrestrial Influences Laboratory in Bulgaria 2005, the possibilities of new network of the Space Weather particle detectors designed by Armenian scientists were presented. Today the network is known as SEVAN (Space Environment Viewing and Analysis Network). In December 2008 the installation of the SEVAN particle detector at Zagreb Astronomical Observatory was finished. It is the first instrument for detecting cosmic rays in Croatia and its installation greatly promotes solar physics research in our country. Here we presented some results obtained from data collected by SEVAN particle detector at Zagreb Astronomical Observatory during the first 10 years of operation. We calculate the barometric coefficients using two statistical methods (least square method and least absolute deviation method). Pressure corrected data is available on a new section of the web page of the Zagreb observatory. Also we investigated diurnal variations of cosmic rays. Example of solar modulation effects (Forbush decrease) and first evidence of registration of TGE (Thunderstorm Ground Enhancement) are also given.
