Atmospheric pressure air plasmas have numerous potential applications that require low power and low gas temperature. The Nanosecond Repetitively Pulsed (NRP) method can generate such plasmas for power budgets lower by several orders of magnitude than traditional plasma generation methods. This study seeks to enlarge the range of application of NRP plasmas to the 300 to 1000 K range. First, we demonstrate the existence of three regimes of the NRP discharge in air at atmospheric pressure and at 1000 K, and then we characterize their chemical, electrical, and thermal properties through optical emission spectroscopy and current-voltage measurements. The three regimes are corona-like (termed C), diffuse-like (D) and filamentary-like (F). The me...
