The problem of nighttime stratospheric NO3Detailed calculations of the behavior of the NO3 column content as a function of time after sunset show that it takes nearly 2 hours to increase from daytime values of approximately 10 to the 11th/sq cm to nighttime values of 10 to the 14th/sq cm. These results appear to be in conflict with the measured NO3-concentration rise time of 40 min after sunset obtained from the 662-nm absorption data of Noxon et al. (1978). Changes in the rate constants affecting the NO, NO2, NO3, N2O5 system, the atmospheric temperature, and the amount of NO2 are not able to bring the calculated rise time for the NO3 column content into agreement with observations.
