Synthetic Solar Irradiance

2021
Synthetic Solar Irradiance: Modeling Solar Data is the first book to cover the principles and methods of this emerging field. Filling a void in the literature, this timely book is edited by one of the world's premiere authorities on synthetic solar irradiance with contributions from other leading experts.

Contributions of the solar ultraviolet irradiance to the total solar irradiance during large flares

Journal of Geophysical Research, 2006
The solar X‐ray radiation varies more than other wavelengths during flares; thus solar X‐ray irradiance measurements are relied upon for detecting flare events as well as used to study flare parameters. There is new information about the spectral and temporal variations of flares using solar irradiance measurements from NASA's Solar Radiation and ...

Monitoring of Solar Irradiance in the High Andes

Photochemistry and Photobiology, 2020
Abstract Solar radiation has been measured in the high Andes near Laguna Lejia (latitude 23° 26′ 23.30" S, longitude 67° 38′ 14.29" W) at an elevation of 4715 m between December 2016 and December 2017. Irradiances were monitored in four wavelength channels: PAR (400–700 nm), UV‐A (315–400 nm), UV‐B (295–315 nm ...

Solar indices and solar u.v.-irradiances

Planetary and Space Science, 1983
Abstract Solar radio fluxes, Zurich relative sunspot number R z , and Solar Call plage indexes daily values for the period 1957–1980 are analyzed in order to test the stability of the series with respect to time and solar activity. It is found that between the series of the 3,8 and 10 cm radio fluxes and the series of R z no significant ...

Solar irradiance monitor

Renewable Energy, 1993
Abstract The data on the intensity distribution of solar radiation is essential for the designer to size solar energy systems, required for specific applications. The solar irradiance monitor has been developed to measure and record solar irradiance data from morning to evening at intervals of 1 min without the presence of a technician or ...

Solar irradiance variations and solar activity

Journal of Geophysical Research: Space Physics, 1982
A mean value for the 1 AU total solar irradiance of 1368.2 W/m2 and a downward trend of 0.05% per year were derived from measurements by the Active Cavity Radiometer Irradiance Monitor (ACRIM) experiment on the Solar Maximum Mission during 1980. Distinct temporary solar irradiance decreases associated with solar activity maxima were observed with a ...

Solar irradiance variability

Atmospheric Research, 1989
Since November 1978 a set of total solar irradiance (TSI) measurements from space is available, yielding a time series of more than 23 years. From measurements made by different space radiometers (HF on NIMBUS 7, ACRIM I on SMM, ACRIM II on UARS and VIRGO on SOHO) a composite record of TSI can be compiled. This leads to a reliable record of TSI with an

Solar Irradiance Variability

Metrologia, 1991
Support is given for the suggestion that the mean annual value of the solar constant varies as an algebraic sum of changes in effective temperature and photospheric radius. A set of harmonic constituents covering the period 1979 to 1987 is suggested.

Solar Irradiance Observations

Science, 1984
The absolute radiometer on Spacelab 1 was used to obtain solar irradiance observations from space. A number of effects must be taken into account in the data reduction. A provisional value was obtained for the mean solar constant during the observation period (6 to 8 December 1983).

Solar UV irradiation and dermal photoaging

Journal of Photochemistry and Photobiology B: Biology, 2001
The skin is increasingly exposed to ambient UV-irradiation thus increasing risks for photooxidative damage with long-term detrimental effects like photoaging, characterized by wrinkles, loss of skin tone and resilience. Photoaged skin displays alterations in the cellular component and extracellular matrix with accumulation of disorganized elastin and ...
