Many experiments have observed a positive correlation between the flux of underground muons and atmospheric temperature. An increase in atmospheric temperature leads to a decrease in atmospheric density, which in turn makes the interaction between mesons and atmospheric molecules less likely, with more mesons decaying into muons. The Daya Bay Reactor Neutrino Experiment has also observed this phenomenon and has measured the correlation coefficient between the muon flux and effective temperature in three experimental halls with different overburdens using two years of data. With more data available in Daya Bay, a more precise measurement of the correlation coefficient is expected. This poster will report on the current status of this measurement in the Daya Bay Reactor Neutrino Experiment.
