Abstract A semi-empirical mass balance method for indirect estimation of urban NOx, and Volatile organic compounds emissions are described. It requires measurement of ambient concentrations of these precursors at urban inflow and outflow boundaries and of the local wind field. In the mass balance, the effect of chemical transformations and removal of the mass balance species (primary as well as secondary) is estimated by means of a crosswind-resolved reactive plume model. As part of an on-going EPA-sponsored project, the method will be applied to existing field data of four eastern U.S. urban areas. The existing data bases were not developed for the present purpose, and are much less than ideal. The outline of a design field study specifically aimed at the current objectives is also described.
