Context. Total solar irradiance changes by about 0.1% between solar activity maximum and minimum. Accurate measurements of this quantity are only available since 1978 and do not provide information on longer-term secular trends. Aims. In order to reliably evaluate the Sun's role in recent global climate change, longer time series are, however, needed. They can only be assessed with the help of suitable models. Methods. The total solar irradiance is reconstructed from the end of the Maunder… 

Solar Magnetic Activity and Total Irradiance Since the Maunder Minimum

Abstract We develop a model for estimating solar total irradiance since 1600 AD using the sunspot number record as input, since this is the only intrinsic record of solar activity extending back far

Reconstruction of solar spectral irradiance since the Maunder minimum

[1] Solar irradiance is the main external driver of the Earth's climate. Whereas the total solar irradiance is the main source of energy input into the climate system, solar UV irradiance exerts

Evolution of the solar irradiance during the Holocene

Context. Long-term records of solar radiative output are vital for understanding solar variability and past climate change. Measurements of solar irradiance are available for only the last three

Reconstructed Total Solar Irradiance as a precursor for long-term solar activity predictions: a nonlinear dynamics approach

Total solar irradiance variations, about 0.1% between solar activity maximum and minimum, are available from accurate satellite measurements since 1978 and thus do not provide useful information on

Solar total and spectral irradiance reconstruction over the last 9000 years

Context.Changes in solar irradiance and in its spectral distribution are among the main natural drivers of the climate on Earth. However, irradiance measurements are only available for less than four

Reconstruction of spectral solar irradiance since 1700 from simulated magnetograms

We present a reconstruction of the spectral solar irradiance since 1700 using the SATIRE-T2 (Spectral And Total Irradiance REconstructions for the Telescope era version 2) model. This model uses as

Models of Solar Total and Spectral Irradiance Variability of Relevance for Climate Studies

The variable radiative output of the Sun is a prime external driver of the Earth’s climate system. Just how effective this driver is has remained relatively uncertain, however, partly due to missing

Towards a long-term record of solar total and spectral irradiance

Modelling total solar irradiance since 1878 from simulated magnetograms

We present a new model of total solar irradiance (TSI) based on magnetograms simulated with a surface flux transport model (SFTM) and the SATIRE (Spectral And Total Irradiance REconstructions) model.



Reconstruction of solar irradiance variations in cycles 21-23 based on surface magnetic fields

Aims. We present a reconstruction of total solar irradiance (TSI) back to 1974, i.e. from the minimum of cycle 21 to the declining phase of cycle 23. We also present a cross-calibration between the

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

Solar Irradiance Variations: From Current Measurements to Long-Term Estimates

Variations of solar total and spectral irradiance are prime solar quantities purported to have an influence on the Earth’s climate. Quantitative estimates of irradiance over as long a time as

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 irradiance

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.

Modeling the Sun’s Magnetic Field and Irradiance since 1713

We use a flux transport model to simulate the evolution of the Sun's total and open magnetic flux over the last 26 solar cycles (1713-1996). Polar field reversals are maintained by varying the

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 we

Can surface magnetic fields reproduce solar irradiance variations in cycles 22 and 23

Total solar irradiance is reconstructed using data from the spectromagnetograph on Kitt Peak for 1992-2003 (cov- ering parts of cycles 22 and 23) and compared with observational data. The model

A reconstruction of total solar irradiance since 1700

The irradiance of the Sun is reconstructed from 1700 to the present, whereby the contributions of active regions and the quiet Sun are modelled separately. A method is proposed which allows the

Effect of spatial resolution on estimating the Sun's magnetic flux

A critical question related to a possible secular trend in the Sun's total magnetic flux and consequently in solar irradiance is the total amount of magnetic flux present on the Sun and how it is
