Description
Vertical profiles of temperature and trace gase concentrations, including O3,H2O, CH4, N2O, CO, HNO3, NO2, NO, HNO4, BrONO2, N2O5,PAN, ClONO2, ClO, CH3Cl, COCl2, CFC-11, CFC-12, HCFC-22, CFC-113, C2H6, C2H2, HCN, OCS, SF6, and others, as well as several aerosol products, are based on improved level-1 calibration and level-2 processing of MIPAS measurements. This global data set provided by IMK/IAA covers the upper troposphere, stratosphere, mesosphere, and for some products also the thermosphere. These data are provided along with TUNER-compliant diagnostics including averaging kernels and a detailed error budget. A novel application of these data is the inference of stratospheric meridional circulation by the direct inversion of the continuity equation. This method uses zonal mean fields of tracers to find those effective meridional velocities that best reproduce the measured fields. A ten-year climatology of stratospheric transport has been generated and shows more detail than available from other observation-based methods.
