The Tibet air shower array has been in operation since 1999 as Tibet III with an energy threshold of a few TeV. As primary cosmic rays are shielded by the Moon having the finite size of 0.5° in diameter, we observe a deficit in cosmic rays called the Moon's shadow with a significance of 40 α level for 1041 live days. The center of the Moon's shadow shifts westward depending on primary cosmic-ray energies due to the geomagnetic field. We calibrate the absolute energy scale of the primary cosmic rays observed by the Tibet III array using this effect. The Moon's shadow simulation, including a precise calculation of the geomagnetic effect, shows a good agreement with observational data. As a result, the systematic error in the absolute energy scale is estimated to be less than approximately ± 8% level by means of the geomagnetic field as a spectrometer.
