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 ...

Solar spectral irradiance and total solar irradiance at a solar minimum

Geomagnetism and Aeronomy, 2014
Results are presented for a wavelet analysis of solar spectral irradiance (SSI) in the ultraviolet to infrared range and total solar irradiance (TSI). The study is based on data collected by the Solar Radiation and Climate Experiment (SORCE) satellite from March 10, 2007 to January 23, 2010. Cross-wavelet analysis finds relationships of varying degrees

Data on total and spectral solar irradiance

Applied Optics, 1983
This paper presents a brief survey of the data available on solar constant and extraterrestrial solar spectral irradiance. The spectral distribution of solar radiation at ground surface, computed from extraterrestrial solar spectral irradiance for several air mass values and for four levels of atmospheric pollution, is also presented.

Total solar irradiance variations

Journal of Atmospheric and Solar-Terrestrial Physics, 1999
Abstract Total solar irradiance has been monitored from space for nearly two decades. These space-borne observations have established conclusively that total solar irradiance changes over a wide range of periodicities—from minutes to the 11-year solar cycle.

Periodicity of Total Solar Irradiance

Solar Physics, 2010
We investigate the periodicity in the PMOD composite of the daily total solar irradiance (TSI) from 21 September 1978 to 9 June 2009. Besides the Schwabe cycle period (10.32 years), the quasi-rotation period is found to be statistically significant in TSI, whose value is about 32 days, longer than that in sunspot activity (27 days), and it ...

Long-term variations in total solar irradiance

Solar Physics, 1994
For more than a decade total solar irradiance has been monitored simultaneously from space by different satellites. The detection of total solar irradiance variations by satellite-based experiments during the past decade and a half has stimulated modeling efforts to help identify their causes and to provide estimates of irradiance data, using ‘proxy ...

Total solar irradiance monitors, space instruments for measuring total solar irradiance on FY-3 satellites

SPIE Proceedings, 2014
Total Solar Irradiance (TSI) has been recorded daily by Total Solar Irradiance Monitors (TSIM) with overlapping measurements on FY-3 (Feng Yun-3) series satellites since 2008. Instrument descriptions, operation in space and flight performance of three TSIMs are presented in this paper.
