Scenarios have been developed and calculations made for aldehyde production from primary and secondary sources within the stable boundary layer after sunset until several hours after sunrise the next day. The sensitivities of production of formaldehyde and several higher molecular weight aldehydes from alkenes to variations in O3 and NO3 concentrations are estimated. Production of aldehydes from alkenes emitted during the 2100h to 0600h period is calculated within the 2100h to 0600h period and the 0600h to 0900h period. The relative production of the aldehydes from primary vehicular sources relative to secondary atmospheric reactions is considered. The contribution from the OH reactions with alkanes to aldehyde production in the 0600h to 0900h period also is estimated.
