Abstract
Results are presented of an experiment to determine extraterrestrial solar spectral irradiance at the earth's mean solar distance within the 300–2500 nm wavelength region. Spectroradiometric measurements were performed during eleven research flights on board a NASA CV-990 aircraft at altitudes between 11.6 km and 12.5 km. Precision of the measurements was better than ±1%. Absolute accuracy of the resultant extraterrestrial solar spectral irradiance is approximately ±3% over most of the measurement range. A listing of results is presented at intervals varying from 0.1 nm throughout most of the uv–visible Fraunhofer region to 5 nm in the continuum region of the ir. Additionally, a listing of solar spectral irradiance, smoothed over the detailed Fraunhofer structure, is presented for engineering use.
