Overview of the NASA Solar Irradiance Science Team (SIST) Program Special Section
Earth and Space Science, 2019 Solar irradiance represents the dominant energy source heating the Earth's atmosphere and climate. Both total solar irradiance and spectral solar irradiance vary over the 11‐year solar cycle.

Retrieval of at-sensor irradiance using Incident Light Sensor (ILS)
, 2002 A number of aircraft sensors have the facility to measure spectral downwelling irradiance using a sensor mounted on the roof of the aircraft, but these data are rarely used for atmospheric correction.

Influence of cloud and solar zenith angle on the diffuse solar erythemal UV short wavelength cut-offs and maximum spectral irradiance wavelengths [PDF]
, 2009 Cloud and the solar zenith angle (SZA) influence the magnitude of the diffuse erythemal UV. The aim of this research was to investigate the variation of the short wavelength cut-off and the maximum spectral irradiance wavelength for the diffuse spectral ...

A new dual-beam technique for precise measurements of spectral reflectance in the field
, 2000 Field spectral measurements made using the single - beam method often include errors due to variation in illumination between measurement of the target and the reference (panel or cosine -corrected receptor).

Influence of Atmospheric Parameters on Biologically Effective Solar UV Irradiance
Annals of West University of Timisoara: PhysicsSolar ultraviolet (UV) radiation has various effects on human beings, both positive and negative. Since solar UV spectral radiation is only rarely monitored, modeling of biologically effective solar UV spectral irradiance became a common practice in ...

Correlations between Total and Spectral Solar Irradiance Variations
The Astrophysical JournalWe compare short-term (seven solar rotations), wavelength-dependent temporal variations in spectral solar irradiance (SSI) with those from the total solar irradiance (TSI). Using space-based measurements, we empirically find good correlations across most
