A high-resolution extraterrestrial solar spectrum has been determined from\udground-based measurements of direct solar spectral irradiance (SSI) over the\udwavelength range from 300 to 500 nm using the Langley-plot technique.\udThe measurements were obtained at the Izaña Atmospheric Research Centre\udfrom the Agencia Estatal de Meteorología, Tenerife, Spain, during the\udperiod 12 to 24 September 2016. This solar spectrum (QASUMEFTS) was combined\udfrom medium-resolution (bandpass of 0.86 nm) measurements of the\udQASUME (Quality Assurance of Spectral Ultraviolet Measurements in Europe)\udspectroradiometer in the wavelength range from 300 to 500 nm\udand high-resolution measurements (0.025 nm) from a Fourier\udtransform spectroradiometer (FTS) over the wavelength range from 305 to\ud380 nm. The Kitt Peak solar flux atlas was used to extend this\udhigh-resolution solar spectrum to 500 nm.  The expanded\uduncertainties of this solar spectrum are 2 % between 310 and\ud500 nm and 4 % at 300 nm. The comparison of\udthis solar spectrum with solar spectra measured in space (top of the\udatmosphere) gave very good agreements in some cases, while in some\udother cases discrepancies of up to 5 % were observed.  The\udQASUMEFTS solar spectrum represents a benchmark dataset with\uduncertainties lower than anything previously published. The\udmetrological traceability of the measurements to the International\udSystem of Units (SI) is assured by an unbroken chain of calibrations\udleading to the primary spectral irradiance standard of the\udPhysikalisch-Technische Bundesanstalt in Germany
