Relative electron-impact-induced emission cross sections for the a 1Πg (v' = 3)–X 1Σ+g (v'' = 0) and a 1Πg (v' = 2)–X 1Σ+g (v'' = 0) transitions are presented. Critical comparison is made with existing cross sections showing significant discrepancy with the widely accepted excitation function of Ajello and Shemansky (1985 J. Geophys. Res. 90 9845–61) at energies below ~80 eV. A series of extensive measurements are presented that were performed to rule out any possible systematic or random errors in the present experimental apparatus and methodology. These efforts lead to the conclusion that the current measurements are robustly reproducible and, thus, should supplant the LBH cross-section shape of Ajello and Shemansky (1985 J. Geophys. Res. 90 9845–61).
OTAY!
We are still yet children in the environment of our world.
It's a particular problem in Cosmology where vast all encompassing theories are based on almost nothing.
We barely know anything about the Sun, the closest and easiest to study star. And yet we're sure we know how stars are born, evolve and die......yeah, right ";^)
Another nail in the AGW coffing. Twice the amount of solar wind hitting the upper atmosphere. And, if I recall, the the temperature being 130,000 degrees it will have a significant impact on temperatures of the upper atmosphere, hence radiational cooling.
Ping of interest. Heat from the Sun in current calculations appears off by at least a factor of 2.
