Daily Solar Irradiance from the Solar Mesospheric Explorer (SME) Ultraviolet Spectrometer
Entry ID: 81-100A-05A


Summary
Abstract: The solar spectrometer onboard the Solar Mesosphere Explorer (SME)
measures ultraviolet radiation in the spectral range of 115.5 to 302.5 nm.
Daily averages of solar irradiance, adjusted to a solar distance of 1 AU,
with a spectral resolution of 1 nm is available on one tape. Improved
solar Lyman-alpha flux at 120, 121, and 122 nm are included in the tape
as a correction to the instrument's wavelength calibration error.

The absolute flux is normalized to a rocket experiment of May 17, 1982 and
is accurate to +/- 15%. The relative accuracy should not be considered
better than +/- 2% per year, and extraction of long-term solar variability
from this data set is not recommended by the investigators.
