我们报告了 2016 年 5 月至 2018 年 5 月期间 NOvA 远探测器记录的多重性超过 15 μ 子轨道的宇宙射线空气簇射的速率。该探测器位于 3.6 米水当量的覆盖层下的表面。我们观察到多μ子流星雨的发生率存在季节性依赖性，其大小随多重性和天顶角的变化而变化。在此期间，有效大气温度和表面压力分别在210 K至230 K和940 mbar至990 mbar之间；淋浴率与有效温度的变化反相关。最高多重性的流星雨的变化比最低多重性的流星雨的变化大约大30%，接近地平线的流星雨的变化比垂直流星雨的变化大20%。
We report the rate of cosmic ray air showers with multiplicities exceeding 15 muon tracks recorded in the NOvA Far Detector between May 2016 and May 2018. The detector is located on the surface under an overburden of 3.6 meters water equivalent. We observe a seasonal dependence in the rate of multiple-muon showers, which varies in magnitude with multiplicity and zenith angle. During this period, the effective atmospheric temperature and surface pressure ranged between 210 K to 230 K and 940mbar to 990mbar, respectively; the shower rates are anti-correlated with the variation in the effective temperature. The variations are about 30% larger for the highest multiplicities than the lowest multiplicities and 20% larger for showers near the horizon than vertical showers.
