High solar cycle spectral variations inconsistent with stratospheric ozone observations
Variability in solar UV radiation is uncertain, but it affects Earth’s climate. Simulations of the ozone response to various data sets of spectral solar irradiance show that high-amplitude solar variability is...

Detection of Solar Rotational Variability in the Large Yield RAdiometer (LYRA) 190 – 222 nm Spectral Band
We analyze the variability of the spectral solar irradiance during the period from 7 January 2010 until 20 January 2010 as measured by the Herzberg channel (190 – 222 nm) of the Large Yield RAdiometer (LYRA) onbo...

Eclipses Observed by Large Yield RAdiometer (LYRA) – A Sensitive Tool to Test Models for the Solar Irradiance
We analyze the light curves of the recent solar eclipses measured by the Herzberg channel (200 – 220 nm) of the Large Yield RAdiometer (LYRA) onboard Project for OnBoard Autonomy (PROBA2). The measurements allow ...
