Journal ArticleDOI
Solar irradiance measurements from a research aircraft.
TL;DR: 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.
Journal ArticleDOI
Solar calibration results from two earth radiation budget experiment nonscanner instruments

TL;DR: Earth radiation budget experiment (ERBE) nonscanner instruments are operating on both the National Aeronautics and Space Administration's earth radiation budget satellite (ERBS) and the National Oceanic and Atmospheric Administration's NOAA-9 spacecraft and show an extremely consistent set of solar measurements.
Journal ArticleDOI
Total and spectral solar irradiance measured at ground surface.
TL;DR: This paper presents the results of a series of total and spectral solar irradiance measurements made at ground surface (Table Mountain Facility, Calif., altitude 2.18 km).
Journal ArticleDOI
Rocket calibration of the Nimbus 6 solar constant measurements.
C. H. Duncan,Royal G. Harrison,J. R. Hickey,J. M. Kendall,M. P. Thekaekara,Richard C. Willson +5 more
TL;DR: Total solar irradiance was observed simultaneously outside the earth's atmosphere by three types of absolute cavity radiometers and duplicates of four of the Nimbus 6 Earth Radiation Budget (ERB) solar channels in a June 1976 Sounding Rocket Experiment.
Journal ArticleDOI
Solar spectral irradiance measured from 11.58 km with a Leiss monochromator and a photoelectric filter radiometer
TL;DR: Solar spectral irradiance measurements were made from NASA's Convair 990 research aircraft using a Leiss double prism monochromator and a GSFC modified Eppley Mark V radiometer, in good agreement with recently published values of Drummond, Laue, and others.
