Abstract
The day-night variation of cosmic rays intensity at sea level has been observed by a simple G-M counter telescope. We preform two 5 hours counting during the day and night and find that the pattern of variation is closely related to the atmospheric disturbance, especially when the observation station is being affected by meterological front or trough. Such effects may lasts for a few days until the trough or fronts weakened. The pattern of variation may be negatively correlated to the altitude of the 0 degC level of the atmosphere. This is closely related to the muon decay effect in the atmosphere. The phenomenon should be further investigation for possible application in weather forecasting.
Cosmic rays are not exclusively associated with the sun. There are a lot of Galactic Cosmic Rays still. It's pretty much leftovers from supernovae, black hole mergers, neutron stars, accretion disks and such. But yeah, at night would be better. Edit: Correction, there is very…
