  In this revue are presented several present activities and experiments at
Alomar observatory and BEO Moussala and the possibility to investigate the
influence of cosmic ray on climate parameters and the impact of cosmic ray to
climate change. The general aim of these experiments is to study the possible
correlation between cosmic ray variation and atmosphere parameters. The
potential to study the possible correlations is discussed. The existing
experiments and devices are presented as well these in preparation and
commissioning. The scientific potential of future and in preparation
experiments is discussed. The possibility to study the space weather at BEO
Moussala and Alomar observatory presented. The specific devises precisely the
muon telescope, neutron flux-meter, Cherenkov light telescope and muon
hodoscope are presented
