Nighttime atmospheric chemistry is simulated in two different situations: an offshore oceanic environment, the Santa Barbara Channel region of the south central coast of California, and a dry environment, the Mojave Desert of California. In the marine case, conversion of NO_x to peroxyacetyl nitrate (PAN) and HNO_3 is rapid; HNO_3 is formed by homogeneous hydrolysis of N_2O_5 and by nitrate radical reactions with organic gases, and the rate of HNO_3 production is limited by the abundance of O_3. Even in the desert case, predictions indicate that homogeneous hydrolysis of N_2O_5 dominates HNO_3 formation at night. The implications of recent studies concerning the unimolecular decomposition of NO_3 are discussed.
