Data Fusion of Total Solar Irradiance Composite Time Series Using 41 Years of Satellite Measurements
Schmutz, W.; Haberreiter, M.; Dudok de Wit, T. +4 more
Since the late 1970s, successive satellite missions have been monitoring the sun's activity and recording the total solar irradiance (TSI). Some of these measurements have lasted for more than a decade. In order to obtain a seamless record whose duration exceeds that of the individual instruments, the time series have to be merged. Climate models …
Photoabsorption cross-section measurements of 32S, 33S, 34S, and 36S sulfur dioxide from 190 to 220 nm
Endo, Yoshiaki; Danielache, Sebastian O.; Ueno, Yuichiro +4 more
The ultraviolet absorption cross sections of the SO2 isotopologues are essential to understanding the photochemical fractionation of sulfur isotopes in planetary atmospheres. We present measurements of the absorption cross sections of 32SO2, 33SO2, 34SO2, and 36
What influence will future solar activity changes over the 21st century have on projected global near-surface temperature changes?
Lockwood, Mike; Jones, Gareth S.; Stott, Peter A.
During the 20th century, solar activity increased in magnitude to a so-called grand maximum. It is probable that this high level of solar activity is at or near its end. It is of great interest whether any future reduction in solar activity could have a significant impact on climate that could partially offset the projected anthropogenic warming. …
High-resolution solar spectral irradiance from extreme ultraviolet to far infrared
Fontenla, J. M.; Snow, M.; Woods, T. +2 more
This paper presents new extremely high-resolution solar spectral irradiance (SSI) calculations covering wavelengths from 0.12 nm to 100 micron obtained by the Solar Irradiance Physical Modeling (SRPM) system. Daily solar irradiance spectra were constructed for most of Solar Cycle 23 based on a set of physical models of the solar features and non-L…
Reconstruction of solar UV irradiance since 1974
Solanki, S. K.; Krivova, N. A.; Podlipnik, B. +1 more
Variations of the solar UV irradiance are an important driver of chemical and physical processes in the Earth's upper atmosphere and may also influence global climate. Here we reconstruct solar UV irradiance in the range 115-400 nm over the period 1974-2007 by making use of the recently developed empirical extension of the Spectral And Total Irrad…
