Solar irradiance reconstruction over the telescopic era using a revised photospheric magnetic field model

Astronomy & Astrophysics
The Sun is the primary source of energy for Earth and one of the main external drivers of its climate. Solar irradiance – the radiative power emitted by the Sun and received at 1 AU – varies on all observable timescales. It is measured as the total solar

Solar Spectral Proxy Irradiance from GOES (SSPRING): a model for solar EUV irradiance

Journal of Space Weather and Space Climate, 2016
Several currently operating instruments are able to measure the full EUV spectrum at sufficient wavelength resolution for use in upper-atmosphere modeling, the effects of space weather, and modeling satellite drag.

Reconstruction of High-Resolution Solar Spectral Irradiance Based on Residual Channel Attention Networks

Remote Sensing
The accurate measurement of high-resolution solar spectral irradiance (SSI) and its variations at the top of the atmosphere is crucial for solar physics, the Earth’s climate, and the in-orbit calibration of optical satellites.

Effects of total solar eclipse of 29 March 2006 on surface radiation [PDF]

Atmospheric Chemistry and Physics, 2007
Solar irradiance spectral measurements were performed during a total solar eclipse. The spectral effect of the limb darkening to the global, direct irradiance and actinic flux measurements was investigated.

Analysis of the Long‐Term Stability of TSI Instruments Using Allan Deviation and the Generation of a New TSI Composite

Earth and Space Science
The dominant external forcing to Earth's climate system is solar radiation, referred to as the solar spectral irradiance (SSI) and the total solar irradiance (TSI), which is the integral of SSI over all wavelengths.

Estimation of Solar UV Irradiance Under Clear-Sky Conditions from Broadband Radiometric Measurements

Atmosphere
It is well known that broadband solar irradiance is measured with a much higher spatial density than ultraviolet (UV) solar irradiance. Building on this, this study proposes a new model for estimating clear-sky global UV solar irradiance based on ...

Spectral Irradiance Observations and Projections for Solar Cycle 25

Earth and Space Science
The Ozone Monitoring Instrument (OMI) on the Aura satellite makes near‐daily measurements of solar spectral irradiance (SSI) at wavelengths between 265 and 500 nm for instrument calibration purposes. The low degradation and exceptional stability of OMI's
