Meteorological Effects in Cosmic-Ray Muon Production
Abstract
Atmospheric effects on cosmic ray muon intensity was studied, based on muon data obtained by the Utah 1500 GV Anisotropy Detector. Standard linear regression methods are employed to find an anomalously small high-altitude temperature coefficient and a high surface pressure coefficient, consistent with those reported by Humble et al. (1979). The small, high-altitude temperature coefficient is due to extraneous variance in the temperature data, while the high surface-pressure coefficient is the result of correlations in the data. It is also found that much or all of the l/f behavior of the muon Fourier power spectrum at low frequencies is due to high altitude temperature fluctuations. A predicted muon DFT spectrum is produced, which agrees reasonably well with that calculated from the muon data.
