Reconstructed Solar Irradiance Data, 1200 Years

Summary
Abstract: Data set consists of reconstructed solar irradiance data and cosmogenic nuclide
production (10Be and 14C) from an ice core at the South Pole (Raisbeck 1990).


Based on a quantitative study of the common fluctuations of 14C and 10Be
production rates, we have derived a time series of the solar magnetic
variability over the last 1200 years. This record is converted into
irradiance variations by linear scaling based on previous studies of sun-like
stars and of the Sun's behavior over the last few centuries. The new solar
irradiance record exhibits low values during the well-known solar minima
centered about 1900, 1810 (Dalton), and 1690 AD (Maunder). Further back in
time, a rather long period between 1450 and 1750 AD is characterized by low
irradiance values. A shorter period is centered about 1200 AD, with
irradiance slightly higher or similar to present day values. It is tempting
to correlate these periods with the so-called "little ice age" and "medieval
warm period", respectively. An accurate quantification of the climatic impact
of this new irradiance record requires the use of coupled atmosphere-ocean
general circulation models (GCMs). Nevertheless, our record is already
compatible with a global cooling of about 0.5 - 1 C during the "little ice
age", and with a general cooling trend during the past millennium followed by
global warming during the 20th century (Mann et al. 1999).
