Book excerpt: Models and measurements intercomparison II (MM II) summarizes the intercomparison results from model simulations and observations of stratospheric species. Representatives from 23 modeling groups using 29 models participated in these MM II excercises between 1996 and 1999. Twelve of the models were two-dimensional zonal-mean models while 17 were three-dimensional models. This was an international effort as seven were from outside the U.S.A. Six transport experiments and five chemistry experiments were designed for various models. Models participating in the transport experiments performed simulations of chemically inert tracers providing diagnostics for transport. The chemistry experiments involved simulating the distributions of chemically active trace gases including ozone.
