Stratospheric age of air computed with trajectories based on various 3D-Var and 4D-Var data sets
Stratospheric age trajectories 3D-Var 4D-Var
2009/1/23
The age of stratospheric air is computed with a trajectory model, using ECMWF ERA-40 3D-Var and operational 4D-Var winds. Analysis as well as forecast data are used. In the latter case successive fore...
A 3D-CTM with detailed online PSC-microphysics: analysis of the Antarctic winter 2003 by comparison with satellite observations
3D-CTM PSC-microphysics Antarctic winter
2008/12/5
We present the first detailed microphysical simulations which are performed online within the framework of a global 3-D chemical transport model (CTM) with full chemistry. The model describes the for...
