| Zusammenfassung |
| The retrieval of concentration vertical profiles of atmospheric constituents
from spectroscopic measurements is often an ill-conditioned problem and
regularization methods are frequently used to improve its stability.
Recently a new method, that provides a good compromise between precision and
vertical resolution, was proposed to determine analytically the value of the
regularization parameter. This method is applied for the first time to real
measurements with its implementation in the operational retrieval code of
the satellite limb-emission measurements of the MIPAS instrument and its
performances are quantitatively analyzed. The adopted regularization
improves the stability of the retrieval providing smooth profiles without
major degradation of the vertical resolution. In the analyzed measurements
the retrieval procedure provides a vertical resolution that, in the
troposphere and low stratosphere, is smaller than the vertical field of view
of the instrument. |
