Varying conditions in the atmosphere affect the propagation of cosmic ray muons. Adequate description of variations induced by meteorological effects is necessary for understanding the variations of non-atmospheric origin. Two novel methods for analysis of meteorological effects are introduced. Both are fully empirical and require knowledge about atmospheric pressure and temperature profile of the atmosphere. First method is based on principal component analysis, while second is based on multivariate regression algorithms. Muon count time series thusly corrected for meteorological effects have significantly smaller variance and reduced amplitude of annual variation. Methods are universally applicable and allow for easy extension of the set of input variables.
