11,000 Year Sunspot Number Reconstruction
Entry ID: NOAA_NCDC_PALEO_2005-015


Summary
Abstract:

From http://www.ncdc.noaa.gov/paleo/pubs/solanki2004/solanki2004.html


Direct observations of sunspot numbers are available for the past

four centuries, but longer time series are required, for example,

for the identification of a possible solar influence on climate and

for testing models of the solar dynamo. Here we report a

reconstruction of the sunspot ...


The series of reconstructed 10-yr averaged sunspot numbers with their 68%

uncertainty. Years are given BP (before present), i.e. the calendar AD year,

Yad, is related to the BP year, Ybp, as Yc=1950-Ybp. The tabulated years

correspond to centers of the corresponding 10-year intervals. Negative values

are artifacts and are consistent with zero within the error limits.
