摘要
The distribution of most trace species within the troposphere depends on a complex interplay between chemistry and transport. Holzer and Waugh (2015) introduced the concept of a path- dependent lifetime tau(c)(r), that parameterizes the integrated chemical loss during transport from the source to a given location r. Here we examine whether this parameterization provides a new approach for decoupling transport and chemistry. We present calculations of path-dependent lifetimes for a suite of chlorofluorocarbon replacement gases in a simple 12-box model and show that for trace species with global lifetimes from 0.5 years to 50 years tau(c) provides an accurate representation of the integrated chemical loss during transport.
