49 Conclusions MIPAS is providing multidimensional information of atmospheric composition. MIPAS data can be used to study climatology, chemical and dynamical processes, PSC and non-lte conditions. With MIPAS it is possible to identify sources and sinks of the molecules in the stratosphere. MIPAS data have been successfully assimilated in weather prediction (NWP) models and chemical and transport models (CTM). Day 6 Lecture 2 Results for the stratosphere - Bruno Carli 49
