Carbon dioxide, Ozone, Water vapor etc are common examples of atmospheric trace gases. Accurate representation of such tracers in climate models is essential to obtain accurate climate predictions. While most models, using different numerics and grids, get the simulated global mass transport correct, there is still a huge spread in tracer transport in such state-of-the-art models. In this study, we create a mathematical framework, to understand and resolve these differences in tracer transport across models. We consider modern dynamical cores(used for climate and weather prediction), developed at Princeton-GFDL and NCAR, that use a wide range of numerics(Pseudospectral, Finite Volume and Spectral Element) and use an idealized tracer called age-of-air to compute the mean residence times of tracers in the stratosphere and create a benchmark study for climate dynamical cores.
