Solar irradiance variability

Studying Solar Irradiance Variability With Wavelet Technique

The detection of variations in solar irradiance by satellitebased experiments during the last 17 years stimulated modelling e orts to help to identify their causes and to provide estimates for irradiance data when no satellite observations exist. Because of the lack of quantitative physical models of solar irradiance, the current empirical models have been developed with linear regression analy...

Irradiance and solar cycle variability: clues in cycle phase properties

We see solar cycle-related variations in almost every coronal, chromospheric, and photospheric measurement obtained over a several-years timescale. With such an abundant observational foundation, we should expect our physical models of the solar cycle to be overconstrained. In fact this is not the case and the ‘‘standard dynamo model’’ is not predictive. This paper describes some new thoughts o...
