Synopsis The atomic parameters of the NII ion, including the energy levels, transition probabilities, collision sections, and collision excitation rate coefficients, have been calculated based on the multi-configuration Dirac-Fock method by implementing Flexible Atomic Code. The ratios of line intensity, I 567.96nm /I 500.52nm , have been calculated by using the collisional-radiative model. The temperatures of six lightning plasma channels were then obtained, and they are consistent with temperatures obtained by using the multi-spectral lines method.
