Abstract:
The SOLar SPECtrum (SOLSPEC) experiment is part of the Solar
Monitoring Observatory (SOLAR) payload, and has been externally
mounted on the Columbus module of the International Space Station
(ISS) since 2008. SOLAR/SOLSPEC combines three absolutely calibrated
double monochromators with concave gratings for measuring the solar
spectral irradiance (SSI) from 166nm to 3088nm. This physical
quantity is a key input for studies of climatology, planetary
atmospheres, and solar physics.
A general description of the instrument is given, including in-flight
operations and performance of the ultraviolet (UV) channel from 175nm
to 340nm.
We developed a range of processing and correction methods, which are
described in detail. For example, methods for correcting thermal
behavior effects, instrument linearity, and especially the accuracy of
the wavelength and absolute radiometric scales have been validated by
modeling the standard uncertainties.
The deliverable is a quiet Sun UV reference solar spectrum as measured
by SOLAR/SOLSPEC during the minimum of solar activity prior to cycle
24. Comparisons with other instruments measuring SSI are also
presented.
Description:
This file provides the data of the Figure 12 of the paper. It is the
average spectral irradiance of the Sun as measured by the space
instrument SOLAR/SOLSPEC on ISS during the minimum of solar activity
prior to cycle 24.
Spectral range: 175nm-340nm by step of 0.5nm.
Time interval for averaging: 6th June 2008 - 26th April 2009.
