Development of the adjoint of geos-chem
WebApr 20, 2012 · [10] The adjoint of the GEOS-Chem model was developed specifically for inverse modeling of aerosol (or their precursors) and gas emissions [Henze et al., 2007]. The advantage of the adjoint approach is its ability to efficiently calculate model sensitivities with respect to large sets of model parameters, such as aerosol emissions at each grid ...
