Spectroscopic diagnostics of laboratory air plasmas as a benchmark for spectral rotational (gas) temperature determination in TLEs
Original language description
We have studied laboratory low pressure (0.1 mbar p 2 mbar) glow air discharges by optical emission spectroscopy to discuss several spectroscopic techniques that could be implemented by field spectrographs, depending on the available spectral resolution,to experimentally quantify the gas temperature associated to transient luminous events(TLEs)occurring at different altitudes including blue jets, giant blue jets, and sprites.Laboratory air plasmas have been analyzed from the near UV(300 nm)to the near IR(1060 nm) with high (up to 0.01 nm) and low (2 nm) spectral resolution commercial grating spectrographs and by an in-house intensified CCD grating spectrograph that we have recently developed for TLE spectral diagnostic surveys with similar or equal to0.45 nm spectral resolution. We discuss the results of lab tests and comment on the convenience of using one or another technique for rotationalgas) temperature determination depending on the altitude and available spectral resolution
