Improved solar Lyman α irradiance modeling from 1947 through 1999 based on UARS observations
The solar Lyman α radiation is the brightest solar vacuum ultraviolet (VUV: λ < 200 nm) emission, and this radiation is deposited in Earth's atmosphere above 70 km. The Lyman α irradiance and itsExpand

The Mg II index: A proxy for solar EUV
This paper shows that the Mg II core-to-wing ratio is a better proxy for Solar Extreme Ultraviolet (EUV) radiation, between 25 and 35 nm than is the F10.7 index. The He II 30.4 nm solar emission, byExpand
