Introduction There is considerable interest in understanding the linkages between regional ozone pollution and global atmospheric chemistry because of the implications for the oxidizing power of the atmosphere, greenhouse radiative forcing by ozone, and intercontinental transport of pollution. Particular focus over the past decade has been placed on the North Atlantic Ocean (NAO) atmosphere through a series of field programs [Parrish, this issue]. We have recently applied the GEOSCHEM global 3-D model of tropospheric chemistry [Bey et al., 2001a] driven by assimilated meteorological observations for 1993-1997 from the NASA Data Assimilation Office (DAO) [Schubert et al., 1993] to a detailed analysis of observations from the 1997 North Atlantic Regional Experiment (NARE) [Fehsenfeld et al., 1996], the Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) [Sturges et al., 1996], and the 2n
