Resolution No.6 (1991): Solar FUV/EUV observation by satellites

IAGA, noting the central importance of solar spectral far ultraviolet (FUV) and extreme ultraviolet (EUV) fluxes to studies of the Earth's thermosphere, ionosphere and mesosphere and recognising the limitations of available indices in the specification of spectral fluxes for quantitative studies, recommends that international and inter-agency cooperative efforts be initiated to provide for future space-borne, long-term solar FUV/EUV spectral flux measurements.
