Models are developed for the photochemistry of a CO_2-H_2O-N_2 atmosphere on Mars and estimates are given for the concentrations of N, NO, NO_2, NO_3, N_2O_5, HNO_2, HNO_3, and N_2O as a function of altitude. Nitric oxide is the most abundant form of odd nitrogen, present with a mixing ratio relative to CO_2 of order 10^(−8). Deposition rates for nitrite and nitrate minerals could be as large as 3× 10^5 N equivalent atoms cm^(−2) sec^(−1) under present conditions and may have been higher in the past.
