[from NOAA/NCDC/WDC Paleoclimatology]
A new compilation of annually resolved time series of atmospheric
trace gas concentrations, solar irradiance, tropospheric aerosol
optical ...
Reconstructed solar total and background irradiances.
11-yr Tootal Solar Irradiance (TSI) component since 1874 is from Foukal and
Lean: earlier from Hoyt Sunspot Groups
Background Brightness component ...
Updated solar irradiance reconstruction. (See also Lean et al., 1995).
Included are time series of annual mean irradiance from 1610 to 2000
of just the 11 year solar irradiance cycle, plus the 11 ...
