Spurio %J Geoscientific Instrumentation, Methods and Data Systems (GI) & Discussions (GID) %D 2012 %I Copernicus Publications %R 10.5194/gi-1-185-2012 %X We present a review of atmospheric muon flux and energy spectrum measurements over almost six decades of muon momentum. Sea level and underground/water/ice experiments are considered. Possible sources of systematic errors in the measurements are examined. The characteristics of underground/water muons (muons in bundle, lateral distribution, energy spectrum) are discussed. The connection between the atmospheric muon and neutrino measurements are also reported. %U http://www.geosci-instrum-method-data-syst.net/1/185/2012/gi-1-185-2012.html
