Analysis of Different Solar Spectral Irradiance Reconstructions and Their Impact on Solar Heating Rates
Proper numerical simulation of the Earth’s climate change requires reliable knowledge of solar irradiance and its variability on different time scales, as well as the wavelength dependence of this variability....

The Solar Spectral Irradiance as a Function of the Mg ii Index for Atmosphere and Climate Modelling
We present a new method to reconstruct the solar spectrum irradiance in the Ly α – 400 nm region, and its variability, based on the Mg ii index and neutron-monitor measurements. Measurements of the solar spectral...

The Shape of the Solar Limb: Models and Observations
In this paper we compare observed, empirical, and modelled solar limb profiles and discuss their potential use to derive physical properties of the solar atmosphere. The PHOENIX, SolMod3D, and COSI radiative t...
