Abstract:
Accurate measurements of the solar spectral irradiance (SSI) and its
temporal variations are of primary interest to better understand solar
mechanisms, and the links between solar variability and Earth's
atmosphere and climate. The SOLar SPECtrum (SOLSPEC) instrument of the
Solar Monitoring Observatory (SOLAR) payload onboard the International
Space Station (ISS) has been built to carry out SSI measurements from
165 to 3088nm. We focus here on the ultraviolet (UV) part of the
measured solar spectrum (wavelengths less than 400 nm) because the UV
part is potentially important for understanding the solar forcing of
Earth's atmosphere and climate. We present here SOLAR/SOLSPEC UV data
obtained since 2008, and their variations in three spectral bands
during Solar Cycle 24. They are compared with previously reported UV
measurements and model reconstructions, and differences are discussed.
Description:
The SOLar SPECtrum (SOLSPEC) instrument of the Solar Monitoring
Observatory (SOLAR) was exposed to sunlight for the first time on
April 5, 2008. The duration to record a solar spectrum (165-3088nm) is
less than 17 minutes. Between April 2008 and May 2016, more than 700
solar spectra were acquired.
The present article is dedicated to the UV portion (165-400nm) of the
solar spectrum and its temporal variations during Solar Cycle 24.
Measurements from two separated double-spectrometers of SOLAR/SOLSPEC
('UV' and 'VIS') are combined. From these data, we obtained the UV
solar spectrum above Earth's atmosphere at a distance of one
astronomical unit (initial values for studying the UV solar
variability).
