The solar spectral irradiance 1200-3184 Å near solar maximum: July 15, 1980
Abstract
Full-disk solar spectral irradiances near solar maximum were obtained in the spectral range 1200-3184 Å at a spectral resolution of approximately 1 Å from rocket observations above White Sands Missile Range, New Mexico, on July 15, 1980. Comparison with measurements made in 1979 and during solar minimum confirms a large increase at solar maximum in the solar irradiance near 1200 Å with no change within our measurement errors near 2000 Å. Irradiances in the range 1900-2100 Å are in excellent agreement with previous measurements, and those in the 2100- to 2500-Å range are lower than the Broadfoot results. We find agreement with previous values 2600-2900 Å and then fall below those values 2900-3184 Å.
