A Correction for Land Contamination of Atmospheric Variables near Land-Sea Boundaries

Abstract

Ocean models need over-ocean atmospheric forcing. However, such forcing is not necessarily provided near the land-sea boundary because (1) the atmospheric model grid used for forcing is frequently much coarser than the ocean model grid, and (2) some of the atmospheric model grid over the ocean includes land values near coastal regions. This paper presents a creeping sea-fill methodology to reduce the improper representation of scalar atmospheric forcing variables near coastal regions, a problem that compromises the usefulness of the fields for ocean model simulations and other offshore applications.
