Solar Data with EUV and soft X-ray bands (down to ~0.5 nm)

[howard@earth_northwestern_edu]

Hi! I was wondering if anyone knows which solar irradiance data includes EUV and soft X-ray bands (in https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/solar/)? The default one (spectral_irradiance_Lean_1610-2009_ann_c100405.nc) only goes down to 120 nm. Thanks in advance for the help!
