The VIRGO Experiment on the ESA/NASA SOHO Mission has three types of
instruments to measure total solar irradiance (TSI) with the absolute
radiometers DIARAD and PMO6V, spectral solar irradiance at ...
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

The goal of the Earth Radiation Budget Experiment is to produce
monthly averages of longwave and shortwave radiation parameters on the
Earth at regional to global scales. Preflight mission analysis ...
