Abstract : The JPL/CalTech O-D, time-dependent photochemical model, we compared the ATLAS-3 MAS measurements to theoretical expectations. The latitudinal and altitudinal gradients are similar for latitudes south of 50 degrees North. Poleward of 50 degrees, unresolved differences remain. After using the model to identify potential problems, the altitude of the peak CIO volume mixing ratio is now in concert with theory. Additional study into the high-latitude disagreement and into the absolute magnitude of Cl sub y partitioning is warranted. p1
