Cheapaml: A simple, atmospheric boundary layer model for use in ocean-only model calculations

Amodel of the marine atmospheric boundary layer is developed for ocean-only modeling in order to better represent air-sea exchanges. This model computes the evolution of the atmospheric boundary layer temperature and humidity using a prescribed wind field. These quantities react to the underlying ocean through turbulent and radiative fluxes. With two examples, the authors illustrate that this formulation is accurate for regional and global modeling purposes and that turbulent fluxes are well reproduced in test cases when compared to reanalysis products. The model builds upon and is an extension of Seager et al.
