Wehrli 1985 AM0 Spectrum

The 1985 Wehrli Standard Extraterrestrial Solar Irradiance Spectrum covers the solar spectrum from 199.5 nm to 10075.0 nm in increments increasing gradually from 1 nm in the shorter wavelengths to 2290 nm at the upper end of the spectrum. Because of the length of this spectrum we have broken the table presented here into 10 smaller tables.
