A generator of the gliding arc jet (GAJ), which is driven by a transverse magnetic field, is developed to produce non-equilibrium plasma at atmospheric pressure. The gas tempera- ture is estimated using the spectrum of OH radicals to be about 2400±400 K. The determinations of electron temperature and electron density by using a line-ratio method are elaborated for the gliding arc jet plasma. This line-ratio method is based on a collisional-radiative model. The experiment results show that electron temperature is about 1.0 eV and electron density is about 6.9x1014 cm-3. Obviously, the plasma of GAJ is in a non-equilibrium state.
