abstract = "The analysis of cosmic ray intensity variation seen by muon
detectors at Earth's surface can help us to understand
astrophysical, solar, interplanetary and geomagnetic phenomena.
However, before comparing cosmic ray intensity variations with
extraterrestrial phenomena, it is necessary to take into account
atmospheric effects such as the temperature effect. In this work,
we analyzed this effect on the Global Muon Detector Network
(GMDN), which is composed of four ground-based detectors, two in
the northern hemisphere and two in the southern hemisphere. In
general, we found a higher temperature influence on detectors
located in the northern hemisphere. Besides that, we noticed that
the seasonal temperature variation observed at the ground and at
the altitude of maximum muon production are in antiphase for all
GMDN locations (low-latitude regions). In this way, contrary to
what is expected in high-latitude regions, the ground muon
intensity decrease occurring during summertime would be related to
both parts of the temperature effect (the negative and the
positive). We analyzed several methods to describe the temperature
effect on cosmic ray intensity. We found that the mass weighted
method is the one that best reproduces the seasonal cosmic ray
variation observed by the GMDN detectors and allows the highest
correlation with long-term variation of the cosmic ray intensity
seen by neutron monitors.",
