[1] Differences in time- variation between total and ultraviolet solar irradiance could help in separating their influence on climate. We present the first models based on area measurements of magnetic plages from CaK spectroheliograms obtained between 1915–1999. Correlation of our time series of UV irradiance with global temperature, T, accounts for only 20% of the global temperature variance during the 20th century. Correlation of our total irradiance time series with T accounts statistically… Expand
A New Look at Solar Irradiance Variation
We compare total solar irradiance (TSI) and ultraviolet (Fuv) irradiance variation reconstructed using Ca K facular areas since 1915, with previous values based on less direct proxies. Our annualExpand
Reconstruction of the past total solar irradiance on short timescales
[1] The aim of this investigation is to present a new analysis of short-term variations in total solar irradiance by developing regression models and to extend these to epochs when irradianceExpand
Total solar irradiance and climate
Abstract The solar radiation is the fundamental source of energy that drives the Earth’s climate and sustains life. The variability of this output certainly affects our planet. In the last twoExpand
A Century of Solar Ca ii Measurements and Their Implication for Solar UV Driving of Climate
Spectroheliograms and disk-integrated flux monitoring in the strong resonance line of Ca ii (K line) provide the longest record of chromospheric magnetic plages. We compare recent reductions of theExpand
Quiet Sun Contribution to Variations in the Total Solar Irradiance
An analysis of spatially-resolved measurements of the intensity of the photospheric continuum by the Michelson Doppler Imager (MDI) on the SOHO spacecraft indicates that these data can be used toExpand
Sources of Solar Total Irradiance Variations
The daily images and magnetograms acquired by MDI are a rich source of information about the contributions of different types of solar regions to variations in the total solar irradiance (TSI). TheseExpand
Temporal Variations in Solar Irradiance Since 1947
The study of variations in total solar irradiance (TSI) and spectral irradiance is important for understanding how the Sun affects the Earth’s climate. A data-driven approach is used in this articleExpand
Solar Forcing of Climate
Solar activity is evident both in the equatorial activity centres and in the polar magnetic field variations. The total solar irradiance variation is due to the former component. During theExpand
Total solar irradiance since 1996: is there a long-term variation unrelated to solar surface magnetic phenomena?
Context. Total solar irradiance (TSI) has been measured with space-based instruments since 1978. The TSI during the recent solar minimum in 2009 has been lower than the two former minima around theExpand
Solar Radiation Changes in Japan during the 20th Century : Evidence from Sunshine Duration Measurements
Annual values of sunshine duration (SS) measured in Japan between 1890 and 2002 were used as a proxy for global irradiance (Eg↓) to study trends and changes in solar forcing at the Earth's surface.Expand


Solar total irradiance variations and the global sea surface temperature record
The record of globally averaged sea surface temperature (SST) over the past 130 years shows a highly significant correlation with the envelope of the 11-year cycle of solar activity over the sameExpand
An Empirical Model of Total Solar Irradiance Variation Between 1874 and 1988
The model provides a remarkably good representation of the irradiance variations observed by satellite-borne radiometers between 1980 and 1988, suggesting that the mean total irradiance has been rising steadily since about 1945, with the largest peak so far at about 1980 and another large peak expected during the current solar cycle 22.

Solar Irradiance since 1874 Revisited
We reconstruct the solar irradiance since 1874 employing an evolved version of previously published models and improved sunspot and facular data. A good correlation between reconstructed irradianceExpand
A discussion of plausible solar irradiance variations, 1700-1992
From satellite observations the solar total irradiance is known to vary. Sunspot blocking, facular emission, and network emission are three identified causes for the variations. In this paper weExpand
A measurement of the quiet network contribution to solar irradiance variation
A large increase in quiet network area since the 17th century Maunder Minimum has been suggested as a mechanism for increasing solar irradiance sufficiently to drive global warming. We show that thisExpand
Reconstruction of solar irradiance since 1610: Implications for climate change
Solar total and ultraviolet (UV) irradiances are reconstructed annually from 1610 to the present. This epoch includes the Maunder Minimum of anomalously low solar activity (circa 1645-1715) and theExpand
Evidence for long-term brightness changes of solar-type stars
CHANGES in the brightness of the Sun may introduce further uncertainties into forecasts of global warming by the greenhouse effect. The Sun is known to vary in brightness, on a timescale of years, byExpand
A model of the wavelength dependence of solar irradiance variations
Thevariationofthesolarirradianceoverthesolarcy- cle has a strong wavelength dependence, being larger at shorter wavelengths. Here we present simple models of the spectral de- pendence of irradianceExpand

The sun's total irradiance decreased from 1980 to mid-1985, remained approximately constant until mid-1987, and has recently begun to increase. This time interval covered the decrease in solarExpand
Detection and parameterization of variations in solar mid- and near-ultraviolet radiation (200-400 nm)
