Microwave spectroscopy of the Mars atmosphere [PDF]

open access: yesApplied Optics, 1995
A study of the use of millimeter-wavelength spectral transitions to investigate the atmosphere of Mars is presented. In the model experiments investigated it is assumed that a spectrometer in the frequency range from 100 to 260 GHz looks into a modest ...

Nitrogen Fixation at Paleo‐Mars in an Icy Atmosphere

open access: goldGeophysical Research Letters
Recent findings of NO near Gale Crater on Mars have been explained by two pathways: formation of nitric acid (HNO3) in a warm climate or formation of peroxynitric acid (HO2NO2) in a cool climate.
