  After more than seven years of data taking with the full IceCube detector
triggering at an average rate of 2.15 kHz, a sample of half a trillion muon
events is available for analysis. The extreme temperature variations in the
stratosphere together with the high data rate reveal features on both long and
short time scales with unprecedented precision. In this paper we report an
analysis in terms of the atmospheric profile for production of muons from decay
of charged pions and kaons. We comment on the implications for seasonal
variations of neutrinos, which are presented in a separate paper at this
conference.
