| Zusammenfassung |
| It was recently found that spectral solar incident flux (SIF) as
a function of the ultraviolet wavelengths exhibits 1/f-type
power-law correlations. In this study, an attempt was made to
explore the residues of the SIF with respect
to the Planck law over a wider range of wavelengths,
from 115.5 to 629.5 nm.
Using spectral, Haar and Detrended Fluctuation analyses, we show that over
the range from 10–20 nm to the maximum lag (≈ 500 nm), the SIF
residues have a scaling regime with fluctuation exponent H ≈ 0.37 but
with high intermittency (C1 ≈ 0.16, multifractal index
α≈ 1.7) and spectral exponent ≈ 1.46. Over the shorter
wavelengths range we found on the contrary low intermittency (C1 ≈ 0) with spectral exponent ≈ 1 and H ≈ 0. |
