| Zusammenfassung |
| In order to avoid problems connected with the content of a priori information
in volume mixing ratio vertical profiles measured with the Michelson
Interferometer for Passive Atmospheric Sounding (MIPAS), a user-friendly
representation of the data has been developed which will be made available in
addition to the regular data product. In this representation, the data will be
provided on a fixed pressure grid coarse enough to allow a virtually
unconstrained retrieval. To avoid data interpolation, the grid is chosen
to be a subset of the pressure grids used by the Chemistry–Climate Model
Initiative and the Data Initiative within the Stratosphere-troposphere
Processes And their Role in Climate (SPARC) project as well as the
Intergovernmental Panel of Climate Change climatologies and model calculations.
For representation, the profiles have been transformed to boxcar base functions,
which means that volume mixing ratios are constant within a layer. This
representation is thought to be more adequate for comparison with model data.
While this method is applicable also to vertical profiles of other species,
the method is discussed using ozone as an example. |
