The Sun’s net radiative output varies on timescales of minutes to gigayears. Direct measurements of the total solar irradiance (TSI) show changes in the spatially- and spectrally-integrated radiant energy on timescales as short as minutes to as long as a solar cycle. Variations of ~0.01% over a few minutes are caused by the ever-present superposition of convection and oscillations with very large solar flares on rare occasion causing slightly-larger measurable signals. On timescales of days to…

Abstract Variations of the total solar irradiance (TSI) over long periods of time provide natural Earth-climate forcing and are thus important to monitor. Variations over a solar cycle are at the 0.1…
Variability in Irradiance and Photometric Indices During the Last Two Solar Cycles
The Total Solar Irradiance (TSI) primarily varies on an 11-year time scale and is governed by features such as sunspots and associated decay products such as plage and faculae. These short-lived…
Placing limits on long-term variations in quiet-Sun irradiance and their contribution to total solar irradiance and solar radiative forcing of climate
TLDR
Reconstruction of total solar irradiance since 1995 presents reconstructions that add quiet-Sun TSI and its uncertainty to models that reconstruct the effects of sunspots and faculae and shows that the most likely upward drift inquiet-Sun radiative forcing since 1700 is between +0.07 and −0.13 W m−2.
The nature of solar noise (SUBMITTED VERSION)
The solar brightness varies on timescales from minutes to decades1, 2. Determining the sources of such variations, often referred to as solar noise, is of importance for multiple reasons: a) it is…
Revised historical solar irradiance forcing
Context. There is no consensus on the amplitude of historical solar forcing. The estimated magnitude of the total solar irradiance (TSI) difference between the Maunder minimum and the present time…
Response of Solar Irradiance to Sunspot-area Variations
One of the important open questions in solar irradiance studies is whether long-term variability (i.e., on timescales of years and beyond) can be reconstructed by means of models that describe…
Solar Irradiance Variability Monitor for the Galileo Solar Space Telescope Mission: Concept and Challenges
Long and reliable total solar irradiance (TSI) time series is one of the essential parameters for understanding solar contributions to climate change. The minor fluctuations of TSI in long timescales…
Spectral variability of photospheric radiation due to faculae I: The Sun and Sun-like stars
Context. Stellar spectral variability on timescales of a day and longer, arising from magnetic surface features such as dark spots and bright faculae, is an important noise source when characterising…
Solar total and spectral irradiance reconstruction over the last 9000 years
Context.Changes in solar irradiance and in its spectral distribution are among the main natural drivers of the climate on Earth. However, irradiance measurements are only available for less than four…
Degradation Correction of TSIS SIM
An understanding of solar variability over a broad spectral range and broad range of timescales is needed by scientists studying Earth’s climate. The Total and Spectral Solar Irradiance Sensor (TSIS)…
