摘要：We report on the observation of the large-scale sidereal anisotropy of Galactic Cosmic Rays (GCRs) between 10 TeV and 1 PeV, with the data collected by the Tibet Air Shower experiment between October 1995 and February 2010. The method to estimate the energy of GCRs energy is improved, so that the data with zenith angle up to 60 degrees can be used. The two-dimensional intensity map with declination between -30 degree and 90 degree at 300 TeV is well connected with IceCube's observation at 400 TeV in 2012, which gives a global picture about the anisotropy at this energy range. A new struction on the energy dependence of the first harmonic coefficients of the large scale anisotropy is revealed above 100 TeV.
