(meteorobs) Meteor plasma / ionization question

[Thomas Ashcraft]

I am writing a paper on transient luminous events, specifically red 
sprites and am wondering if this sentence is correct:

"Sprites also create a form of plasma ionization although it may differ 
from meteor ionization in that it is supposedly a cold plasma ( 
fluorescence?) rather than the hot plasma of meteors. In any case, the 
sprite ionization proves to be reflective of very high frequency radio 
waves."

I am assuming that meteor plasma is hot but is this actually the case?

Thanks for your reply in advance.
