Zitat von BlinderBarmer
Und die Fachleute sprechen eben von TSI, und nicht von magnetischer Sonnenintensität, und damit widersprichst du doch gerade den Fachleuten, weil du etwas für relevant hältst, was die eben nicht tun.
Und du hältst das genau zu dem Zeitpunkt für relevant, seit dir klargeworden ist, dass TSI dir widerspricht.

Sagen wir mal so: seit mir klar geworden ist, dass Du von Sonnenflecken redest.
TSI ändert sich offenbar nur durch magnetische Aktivität. Daher ist das austauschbar. Aber verwirrend, genau.
"
This agreement provides further evidence that TSI variations are primarily due to solar surface magnetic activity." (

Hier wurde das noch etwas genauer besprochen:
"U
p to now, reconstructions of TSI were based on the assumption that both the solar-cycle modulation and the long-term changes are due to manifestations of surface magnetism [e.g. Wang et al., 2005; Krivova et al., 2007]. In this study we use another approach by considering the knowledge about TSI obtained during the observational period (1978 to the present). Hereby, TSI is represented by the PMOD composite, mainly because it provides a reliable record also during the solar cycle 21 [for details see Frohlich ¨ , 2009]. During the solar minimum in 2008/09 the PMOD composite shows that TSI is much lower than it was during the previous minimum in 1996 and the fact, that e.g. the chromospheric indices and thus the UV radiation do not show a similar distinct decrease, indicates that the long-term trend of TSI is not due to changes of the surface magnetism but a different mechanism. This must, however, be still related to the overall level of activity and it may be due to a change in global temperature of the Sun as already suggested by Tapping et al. [2007]. Moreover, Frohlich ¨ [2009] shows that there is a strong correlation between TSI and the open magnetic field Br during the time of the minima of the observed 30-year-long TSI record. This correlation can be used for reconstructing TSI during minima times whenever Br is known."
