Centennial Total Solar Irradiance Variation [PDF]
Remote Sensing, 2022 Total Solar Irradiance (TSI) quantifies the solar energy received by the Earth and therefore is of direct relevance for a possible solar influence on climate change on Earth.

Reconstruction of Total Solar Irradiance by Deep Learning
Proceedings of the International Florida Artificial Intelligence Research Society Conference, 2021 The Earth's primary source of energy is the radiant energy generated by the Sun, which is referred to as solar irradiance, or total solar irradiance (TSI) when all of the radiation is measured.

Magnitudes and timescales of total solar irradiance variability [PDF]
Journal of Space Weather and Space Climate, 2016 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 Irradiance Variability: Comparisons of Models and Measurements
Earth and Space Science, 2019 The Earth system responds to solar variability on a wide range of timescales. Knowledge of total solar irradiance (TSI) and solar spectral irradiance (SSI) spanning minutes to centuries is needed by scientists studying a broad array of research ...

Solar rotational modulations of spectral irradiance and correlations with the variability of total solar irradiance [PDF]
Journal of Space Weather and Space Climate, 2016 Aims: We characterize the solar rotational modulations of spectral solar irradiance (SSI) and compare them with the corresponding changes of total solar irradiance (TSI).

Living Reviews in Solar PhysicsThe Sun provides nearly all the energy powering the Earth’s climate system, far exceeding all other energy sources combined. The incident radiant energy, the “total solar irradiance,” has been measured by an uninterrupted series of temporally overlapping

Journal of Space Weather and Space Climate, 2022 Studies of the Sun and the Earth’s atmosphere and climate consider solar variability as an important driver, and its constant monitoring is essential for climate models. Solar total and spectral irradiance are among the main relevant parameters. Physical

Solar total irradiance in cycle 23 [PDF]
Astronomy & Astrophysics, 2011 The apparently unusual behaviour of the TSI during the most recent minimum of solar activity has been interpreted as evidence against solar surface magnetism as the main driver of the secular change in the TSI. We test claims that the evolution of the solar surface magnetic field does not reproduce the observed TSI in cycle 23.

Solar oscillations observed in the total irradiance [PDF]
Solar Physics, 1983 AbstractThe total solar irradiance measurements obtained by the active-cavity radiometer on board the Solar Maximum Mission have been analyzed for evidence of global oscillations. We find that the most energetic low-degree p-mode oscillations in the five-minute band have amplitudes of a few parts per million of the total irradiance, and we positively ...
