An influence of solar spectral variations on radiative forcing of climate

  title={An influence of solar spectral variations on radiative forcing of climate},
  author={Joanna D. Haigh and Anne Winning and Ralf Toumi and Jerald W Harder},
The thermal structure and composition of the atmosphere is determined fundamentally by the incoming solar irradiance. Radiation at ultraviolet wavelengths dissociates atmospheric molecules, initiating chains of chemical reactions—specifically those producing stratospheric ozone—and providing the major source of heating for the middle atmosphere, while radiation at visible and near-infrared wavelengths mainly reaches and warms the lower atmosphere and the Earth’s surface. Thus the spectral… 
Solar spectral irradiance variability from SCIAMACHY on daily to several decades timescales
The sun's radiative output is the primary energy input to the Earth, planets, and the entire heliosphere. It determines the thermal structure of the Earth s atmosphere, and overall it sustains life
Recent variability of the solar spectral irradiance and its impact on climate modelling
The lack of long and reliable time series of solar spectral irradiance (SSI) measurements makes an accurate quantification of solar contributions to recent climate change difficult. Whereas earlier
The impact of solar spectral irradiance variability on middle atmospheric ozone
This study presents the impact of solar spectral irradiance (SSI) variability on middle atmospheric ozone over the declining phase of solar cycle 23. Two different types of spectral forcing are
Abstract. The high-resolution measurements of the spectral solar irradiance at the top of the Earth's atmosphere by the Solar Radiation and Climate Experiment (SORCE) satellite suggest significant
The role of the solar irradiance variability in the evolution of the middle atmosphere during 2004–2009
Recent measurements by the Spectral Irradiance Monitor (SIM) and the Solar Stellar Irradiance Comparison Experiment (SOLSTICE) onboard the Solar Radiation and Climate Experiment satellite have
Physical Understanding of Solar Irradiance in Ultraviolet and Radio Wavelengths
Understanding of solar and stellar brightness variability plays a crucial role in the studies of solar-stellar and solar-terrestrial connection. In particular, the modeling of solar brightness
Evaluation of simulated photolysis rates and their response to solar irradiance variability
The state of the stratospheric ozone layer and the temperature structure of the atmosphere are largely controlled by the solar spectral irradiance (SSI) through its influence on heating and
Numerical simulation of climate response to ultraviolet irradiation forcing


The Effect of Solar UV Irradiance Variations on the Earth's Atmosphere
The response of the lower and middle atmosphere to variations in solar irradiance typical of those observed to take place over the 11-year activity cycle has been investigated. The effects on

MANY recent studies have reported an apparent correlation between solar activity and the Earth's climate on the timescale of the 11-year solar cycle1–4 and over longer periods5–10, but to date no
Reconstruction of solar UV irradiance in cycle 23
Solar irradiance variations show a strong wavelength dependence. Whereas the total solar irradiance varies by about 0.1% during the course of the solar cycle, variations at the wavelengths around the
Trends in solar spectral irradiance variability in the visible and infrared
The Spectral Irradiance Monitor (SIM) on‐board the Solar Radiation and Climate Experiment (SORCE) satellite provides the first multi‐year continuous measurements of solar spectral irradiance (SSI)
Understanding the influence of solar variability on the Earth's climate requires knowledge of solar variability, solar‐terrestrial interactions, and the mechanisms determining the response of the
The SORCE SIM Solar Spectrum: Comparison with Recent Observations
The Spectral Irradiance Monitor (SIM) on board the NASA SORCE satellite (Solar Radiation and Climate Experiment) was launched on 25 January 2003 and has been making twice-daily measurements of solar
Evolution of the Sun's Spectral Irradiance Since the Maunder Minimum
Because of the dependence of the Sun's irradiance on solar activity, reductions from contemporary levels are expected during the seventeenth century Maunder Minimum. New reconstructions of spectral
Reconstruction of solar irradiance variations in cycle 23
A model of solar irradiance variations is presented which is based on the assumption that solar surface magnetism is responsible for all total irradiance changes on time scales of days to years. A
