Zusammenfassung |
The combination of data obtained with different sensors (data
fusion) is a powerful technique that can provide target
products of the best quality in terms of precision and
accuracy, as well as spatial and temporal coverage and
resolution. In this paper the results are presented of the
data fusion of measurements of ozone vertical profile
performed by two space-borne interferometers (IASI on METOP
and MIPAS on ENVISAT) using the new measurement-space-solution
method. With this method both the loss of information due to
interpolation and the propagation of possible biases (caused
by a priori information) are avoided. The data fusion products
are characterized by means of retrieval errors, information
gain, averaging kernels and number of degrees of freedom. The
analysis is performed both on simulated and real measurements
and the results demonstrate and quantify the improvement of
data fusion products with respect to measurements of a~single
instrument. |
