    • NOAA Climate Data Record (CDR) of Total Solar Irradiance (TSI), NRLTSI Version 2.0 (Version Superseded)

    Metadata Updated: November 2, 2023

    Note: This dataset version has been superseded by a newer version. It is highly recommended that users access the current version. Users should only use this version for special cases, such as reproducing studies that used this version. This Climate Data Record (CDR) contains total solar irradiance (TSI) as a function of time created with the Naval Research Laboratory model for spectral and total irradiance (version 2). Total solar irradiance is the total, spectrally integrated energy input to the top of the Earth's atmosphere, at a standard distance of one Astronomical Unit from the Sun. Its units are W per m2. The dataset was created by Judith Lean (Space Science Division, Naval Research Laboratory), Odele Coddington and Peter Pilewskie (Laboratory for Atmospheric and Space Science, University of Colorado). The daily- and monthly-averaged TSI data range from 1882 to the present, and annual-averaged TSI data begin in 1610. The data file format is netCDF-4 following CF metadata conventions. The dataset is accompanied by algorithm documentation, data flow diagram and source code for the NOAA CDR Program.

    Lineage The data were produced by the Naval Research Laboratory and the University of Colorado, and are archived at the NOAA National Centers for Environmental Information (NCEI). Version 2 indicates the current version of the Naval Research Laboratory solar variability models, denoted NRLTSI2 and NRLSSI2, for total solar irradiance and solar spectral irradiance, respectively. This version labeling distinguishes the models from their original formulation, NRLTSI and NRLSSI (i.e,. Version 1, or original version). The Solar Irradiance Climate Data Record transitioned to the NOAA CDR program is specific to Version 2, although the original formulation of the model has created solar irradiance records used in many previous climate modeling studies, including for the IPCC.
