Název v původním jazyce

Spectroscopic diagnosis of laboratory air plasmas as a benchmark for spectral rotational (gas) temperature determination in TLEs(ICPIG2013)

Popis výsledku v původním jazyce

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 with Transient Luminous Events (TLEs) occurring at different altitudes including blue jets, giant blue jets and sprites.Laboratory air plasmas have been analysed 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 developed intensified CCD grating spectrograph that we have recently developed in our group at IAA-CSIC for TLE spectral diagnostic surveys with 0.45nm spectral resolution.We discuss the results of lab tests and comment on the convenience of using one or another technique for rotationa (gas)temperature determination during TLE spectroscopic campaigns.
