LISIRD supplied Composite Solar Spectral Irradiance

This data product contains daily-averaged solar spectra over the UV range 120-400 nm in 1 nm bins from multiple spacecraft, including SME, Nimbus 7 SBUV, NOAA 9 and 11 SBUV/2, UARS SUSIM and UARS SOLSTICE. Data are available from 1978-Nov-08 to 2005-Aug-01. Data include irradiances and their absolute and long-term uncertainties. Data are available both as a zipped text data file and as an IDL save file via LISIRD at LASP. The data set was created by Matthew DeLand of SSAI.
