Metastable species were detected both in a thin surface plasma layer and in the space afterglow through plasma induced emission and optical-optical double resonance laser induced fluorescence, respectively. Basically, the observed N2(A3+u) species follow the discharge current oscillations in the plasma layer, while they evolve on a millisecond time scale due to diffusion through the space afterglow. Emission spectrometry provides a rough estimation of average metastable concentration in a thin surface plasma layer similar to 9x1013 cm-3. Fluorescence measurements then allow an upper estimation of metastable concentration in the space afterglow <= 1x1012 cm-3.
