The IAU Colloquium No. 143 "The Sun as a Variable Star: Solar and
Stellar Irradiance Variations" was held on June 20 - 25, 1993 at
the Clarion Harvest House, Boulder, Colorado, USA. The main
objective of this Colloquium was to review the most recent results
on the observations, theoretical interpreta tions, and empirical
and physical models of the variations observed in solar and stellar
irradiances. A special emphasis of the Colloquium was to discuss
the results gained on the climatic impact of solar irradiance
variability. The study of changes in solar and stellar irradiances
has been of high interest for a long time. Determining the absolute
value of the luminosity of stars with different ages is a crucial
question for the theory of stellar evolu tion and energy production
of stellar interiors. Observations of the temporal changes of solar
and stellar irradiances - in the entire spectral band and at
different wavelengths - provide an additional tool for studying the
physical processes below the photosphere and in the solar- stellar
atmospheres. Since the Sun's radiative output is the main driver of
the physical processes with in the Earth's atmosphere, the study of
irradiance changes is an extremely important issue for climatic
studies as well. Climatic models show that small, but persistent
changes in solar irradiance may influence the Earth's climate.

Measurements of solar irradiance, both bolometric and at various
wavelengths, over the last two decades have established
conclusively that the solar energy flux varies on a wide range of
time scales, from minutes to the 11-year solar cycle. The major
question is how the solar variability influences the terrestrial
climate. The Solar Electromagnetic Radiation Study for Solar Cycle
22 (SOLERS22) is an international research program operating under
the auspices of the Solar-Terrestrial Energy Program (STEP) Working
Group 1: The Sun as a Source of Energy and Disturbances'. STEP is
sponsored by the Scientific Committee of Solar-Terrestrial Physics
(SCOSTEP) of the International Council of Scientific Unions (ICSU).
The main goal of the SOLERS22 1996 Workshop was to bring the
international research community together to review the most recent
results obtained from observations, theoretical interpretation,
empirical and physical models of the variations in the solar energy
flux and their possible impact on climate studies. These questions
are essential for researchers and graduate students in
solar-terrestrial physics.

The papers in this volume aim to represent the most up-to-date
research contributions on the observations, theoretical
interpretations, and empirical and physical models of variations
observed in solar and stellar irradiances, as well as on
Sun-climate connections. Both theoretical studies and irradiance
observations show that the energy output of the Sun and solar-type
stars varies, changing on time scales related to the short-term
surface manifestations of solar/stellar magnetic activity as well
as long-term modulations driven by processes in the interiors of
the stars. Papers presented in this book point out that at the
Earth these variations influence the terrestrial climate, radiative
environment and upper atmospheric chemistry.
