Dependence of barometric correction coefficient on geomagnetic conditions
Abstract
The results of studies of the barometric coefficient for the muon component of cosmic ray showers are discussed. Data were gathered with a multidirectional telescope, an underground telescope for measuring the very hard component, and from balloon soundings for the barometric pressure. Linear and logarithmic regressions and simultaneous correlation and daily harmonics were performed to obtain the correlation coefficients for magnetically quiet days and for the isobaric level. Variations in the coefficients were observed with time and with geomagnetic activity. It is recommended that calculations of long term correlation coefficients for cosmic ray shower measurements be avoided.
