Some Statistical Properties of the ELITE Data Set
conference paper
We present some remarkable results of our analysis of the lidar data set of the ELITE measurements at 1.06 um. The data are obtained from Dr. W. Renger (Deutsche Forschungsanstalt für Luft- und Raumfahrt e.V., DLR Institut für Fysik der Atmosphäre) and from Dr. J. Pelon (Service d'Aeronomie du CNRS, Paris). From the ELFTE data set, that contains about 200 Mbytes of data, a selection has been made to study statistical properties of cirrus clouds. The work is carried out in a current project funded by ESA (ESTEC contract No. 11766/96/NL/CN). We have estimated statistics concerning moments, (cross-) correlations, spectral power density distributions and two-point variance (structure function) distributions. In this paper we include some results in addition to those presented during the oral presentation at the workshop. The main conclusion is that spectra that represent the whole data set, obtained after averaging many local spectra, clearly show the characteristics of Brownial fractals, namely, they can be fitted well by A.f 'P distributions (A and p are constants, f denotes the spatial frequency). For the vertical direction we find p = 2.2, for the horizontal direction p = 1.4. A quick-look comparison with spectra that we calculated for part of the ELAC campaign data (LEANDRE flights in France) supports the findings.
