LISIRD supplied Composite Lyman Alpha

ResourceID
spase://NASA/NumericalData/LASP/LISIRD/Composite/Lyman.Alpha/P1D

Description

This data product contains daily irradiance levels
(photons/s/cm**2) of solar Lyman alpha (121.5 nm) radiation from multiple
spacecraft and modelling sources, including AE-E/ESUM, SME/SUVM,
UARS/SOLSTICE, TIMED/SEE and SORCE/SOLSTICE spacecraft and F10.7 and Mg
models. Data are available from 1947 to near-current, both graphically
and, in txt/csv format, digitally, from the LISIRD interface at
U.Colorado/LASP.
