Description Atmospheric pressure rare gases of helium, neon and argon were investigated by means of high speed ICCD camera for the presence of striated structures in single pair strips geometry of coplanar dielectric barrier discharge. In helium stratification occurs over the instantaneous anode. In neon two distinct regimes of striation were observed - spatially stable diffuse over the anode, and unstable filamentary over the interelectrode gap and anode. In argon only the filamentary striation regime was observed.
