| Popis: | Measurements of the solar constant and solar spectrum were made from a research aircraft flying at 11.58 km, above almost all of the highly variable and absorbing constituents of the atmosphere. A wide range of solar zenith angles was covered during six flights for over 14 h of observation. Results are presented from nine different instruments which complemented each other in measuring techniques and wavelength range and were calibrated and operated by different experimenters. A new value of the solar constant, 135.1 mW cm(-2), has been derived, as well as a revised solar spectral irradiance curve for zero air mass. |
