• The JB2006 empirical thermospheric density model (2008, methodology): “The result is a measure of chromospheric and some photospheric solar active region activity independent of instrument sensitivity change through time, and is referred to as the Mg II cwr, which is provided daily by NOAA Space Environment Center (SEC) (Viereck et al., 2001).”
• Solar Irradiance Variability and Climate (2013, methodology): “The widely used Mg II index is the ratio of the brightness in the cores of the Mg II lines to their wings, making it relatively insensitive to instrumental degradation with time (Viereck et al. 2001).”
• Flare Irradiance Spectral Model (FISM): Daily component algorithms and results (2007, background): “The Mg II core-to-wing ratio [Heath and Schlesinger, 1986; Viereck et al., 2001; Viereck et al., 2004] most accurately portrays the chromospheric emissions, along with the continuum emissions in the FUV wavelengths.”
