McGillicuddy Jr., Dennis J. Ballabrera-Poy, Joaquim Model initialization Hydrographic skill Objective analysis Data assimilation 9 pages, 8 figures, 4 tables A simple improvement to objective analysis of hydrographic data is proposed to eliminate spatial aliasing effects in tidally energetic regions. The proposed method consists of the evaluation of anomalies from observations with respect to circulation model fields. The procedure is run iteratively to achieve convergence. The method is applied in the Bay of Fundy and compared with traditional objective analysis procedures and dynamically adjusted climatological fields. The hydrographic skill (difference between observed and model temperature and salinity) of the dynamically adjusted objective analysis is significantly improved by reducing bias and correcting the vertical structure. Representation of the observed velocities is also improved. The resulting flow is consistent with the known circulation in the Bay The preparation of this paper was supported by NSF/NIEHS Grant OCE-0430724 (Woods Hole Center for Oceans and Human Health) and NOAA Grant NA06NOS4780245 (GOMTOX).
