Spacecraft measurements have established that the total radiative output of the Sun varies at the 0.1–0.3% level. The observed fluctuations are well modelled as radiative deficits proportional to the area of the solar disk covered by sunspots. Historical records of projected sunspot areas allow an accurate reconstruction of these short-term fluctuations over the past century. Such changes can be expected to perturb the terrestrial surf ace temperature by a fraction of a degree centigrade and… 
The Climatic Impact of Secular Variations in Solar Irradiance
Variations in solar luminosity are expected to give rise to variations in average sea-surface temperatures (SST). We explore this possibility using both indirect evidence on the variability of
Solar signals in global climatic change
Based on the physical background that varying solar activity should lead to variations of the ‘solar constant’ and that the climate system may respond sensitively even to small solar variations, a
Solar variability and oscillations
Within this decade, observations of total solar irradiance have become good enough to permit us to study directly the solar luminosity variations on a wide range of time scales, up to several years.
Active region influences upon the solar constant
In this paper we discuss the influence that active regions have upon the solar constant. Sunspots appear to lower the solar constant for the few days in which they are located near central meridian.
Possible influences of solar radiation variations on the atmospheric circulation in the northern hemisphere of the earth
The strength of the circumpolar zonal circulation of the atmosphere in the northern hemisphere, expressed by an index calculated from the air pressure gradient between 35° N and 65°N, shows a
Solar irradiance modulation by active regions from 1969 through 1981
Recent satellite measurements of the solar total irradiance (S) indicate that on time scales of days to months the solar constant varies by a few tenths of a percent. The predominant part of these
An Empirical Model of Total Solar Irradiance Variation Between 1874 and 1988
TLDR
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.

The effect of sunspots and faculae on the solar constant.
We study the available measurements of the solar constant made at ground sites and from recent space observations to determine whether sunspots or faculae produce a detectable modulation of either

The climate, as represented by the mean Northern Hemisphere temperature, has shown substantial changes within the past century. The temperature record is utilized as a means of elucidating the
Solar flux and its variations
We present data on the solar irradiance as derived from a number of sources. An attempt was made to bring these data onto a uniform scale. The results are presented in Table IV and Figure 6.
Observations of solar irradiance variability.
TLDR
Measurements of total solar irradiance show the irradiance to have been variable throughout the first 153 days of observations, and suggest that considerable energy storage occurs within the convection zone in solar active regions.

Sunspots have an obvious direct effect upon the visible radiant energy falling upon the Earth. We show how to estimate this effect and compare it quantitatively with recent observations of the solar

Long-term changes in the level of solar activity are found in historical records and in fossil radiocarbon in tree-rings. Typical of these changes are the Maunder Minimum (A.D. 1645–1715), the Spörer

The solar constant is calculated as a function of time using known contrast values for active features on the Sun. The photospheric effective temperature is assumed to be constant in this model and
