Description

The evolution of the Earth's climate is of growing concern. There is evidence of a causal relationship between cosmic ray muon flux and cloud cover and it is expected that long term variations in cosmic ray flux may influence Earth's temperature changes [1]. It has been observed that a muon telescope with a variable angular acceptance at Earth's surface can be used to study correlations between flux distribution and barometric pressure. The muon flux from the cosmic ray particles positively correlates with seasonal temperature variations and anti-correlates with pressure variations [2]. In this talk, the construction of a new two scintillator paddle telescope prototype will be presented along with preliminary results from this detector.
