The F10.7 index is a critical value used in modeling of the upper atmosphere. If the index is unavailable the closest way to reconstruct it is by using solar radio fluxes at other wavelengths. Sunspot number can also be used to reconstruct F10.7 but rotation, running means, or constant values do not provide good approximations.
