Ozone depletion in the 2006/2007 Arctic winter
Ozone depletion in the 2006/2007 Arctic winter is studied by assimilating ozone from the Odin/SMR satellite instrument into a 2-D isentropic transport model. Cross-isentropic transport is implemented by letting the vortex descend at a rate estimated from the inert tracer N2O. Ozone depletion is esti...
