GOES-16 was calculated with the Vendor original SRF and the solar spectral irradiance of "MNewKur" (modified New Kurucz) from MODTRAN 4.0.
GOES-17 was calculated with the CWG processed SRF and the spectral solar irradiance of "MNewKur" (modified New Kurucz) from MODTRAN 4.0.
GOES-18/19 were calculated with CWG processed SRF and TSIS-1 Hybrid Solar Reference Spectrum (HSRS).
