“…Oxidizers such as hydrogen peroxide can destroy organics at the surface of Mars (Oyama et al, 1977). Hydrogen peroxide (H 2 O 2 ) is produced by photochemical processes (Krasnopolsky et al, 1993;Atreya and Gu, 1994;Nair et al, 1994), and it was recently detected on Mars (Encrenaz et al, 2003Clancy et al, 2004). The abundance of H 2 O 2 was observed to vary between 20 ppbv and 40 ppbv around the planet , in agreement with predictions of photochemical models at the season of the observations.…”

“…The recent discovery of H 2 O 2 in the atmosphere of Mars (1,2) supports the hypothesis that oxidation of iron by photochemically generated H 2 O 2 over the past 4 billion years may have yielded the present oxidized Martian surface (3). The cold, dry, and low-oxygen (Ϸ7 bar) Martian atmosphere concentrates H 2 O 2 production near the surface (4,5). Hydrogen peroxide can be preserved readily in ice, because H 2 O 2 has a slightly lower freezing point (Ϫ1°C) than H 2 O; a concentration of H 2 O 2 as high as 0.13% is observed on the surface of the Galilean satellite Europa (6).…”

“…where n i is the number density for species i, i is the vertical flux, P i is the chemical production rate, and L i is the chemical loss rate, all evaluated at time t and altitude z. P i and L i are calculated based on the chemical schemes published in the literature (4,(25)(26)(27). The vertical flux is given by…”

“…We note that some models show an increase of the CO mixing ratio above an altitude of 40 km because of transport (Theodore et al 1993;Nair et al 1994). We have chosen to set this parameter to a constant value in order to simplify the problem, as the only line sensitive to q CO is the 13 CO(2−1) line (optically thin).…”
