Mars: Has Nitrogen Escaped?

If eddy mixing is about as effective on Mars as it is on Earth, then there seems to be less nitrogen present on Mars than we would expect if terrestrial-type outgassing were the source. However, in this event a nonthermal escape mechanism involving the predissociation of exospheric nitrogen can be invoked to explain the low nitrogen concentration.
