             abstract = "The negative atmospheric temperature effect observed in the muon 
                         intensity measured by surface-level detectors is related to the 
                         atmospheric expansion during summer periods. According the first 
                         explanation given, the path of muons from the higher atmospheric 
                         level (where they are generated) to the ground becomes longer, and 
                         more muons decay, leading to a muon intensity decrease. A 
                         significant negative correlation, therefore, is expected between 
                         the altitude of the equi-pressure surface and the muon intensity. 
                         We compared measurements of the altitude of 100 hPa equi-pressure 
                         surface and data from the multidirectional muon detector installed 
                         at the Brazilian Southern Space Observatory in S{\~a}o Martinho 
                         da Serra, RS. Significant correlation coefficient were found (up 
                         to 0.95) when using data observed in 2008. For comparison, data 
                         from the multidirectional muon detector of Nagoya, located in the 
                         opposite hemisphere, is studied and an anti-phase in the cosmic 
                         ray variation related with the temperature effect is expected 
                         between data from detectors of Nagoya and S{\~a}o Martinho da 
                         Serra. The temperature influence is higher for the directional 
                         channels of Nagoya than for ones of S{\~a}o Martinho da Serra.",
