Aragats Space Environmental Center (ASEC) detectors are continuously measuring fluxes of secondary cosmic rays with various energies,  also elctric and magnetic fields. Our group is  mainly focused on the analysis of this huge amount of data, which is obtained from the  measurements. The main topics of research are thunderstorm physics and solar-terrestrial physics. Using Geant4 package simualtions of ASEC detectors' responce and so called Relativistic Runaway Electron Avalanches (RREA) are performed.
