        abstract:  *Note: This dataset version has been superseded by a newer version.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 solar spectral irradiance (SSI) as a function of time and wavelength created with the Naval Research Laboratory model for spectral and total irradiance (version 2). Solar spectral irradiance is the wavelength-dependent 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 per nm. Also included is the value of total (spectrally integrated) solar irradiance in units 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 SSI data range from 1882 to the present, and annual-averaged SSI 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.
        purpose:  The purpose of this Climate Data Record is to provide a continuous and long-term record of solar spectral irradiance (SSI) for scientists and modelers in the solar, atmospheric and chemistry sciences as well as the energy industry.

        supplementalInformation:  Comment on summing the CDR SSI into Broad Wavelength Bands: Summing the solar spectral irradiance into broader wavelength bands than those of the CDR wavelength bins requires summing the irradiance in each bin (W m-2 nm-1) over all bins within the desired wavelength band and accounting for the (variable) bandwidth of each bin. For example, the total spectral irradiance (W m-2) in a spectral band bounded on the lower end by 'wav1' and on the upper end by 'wav2' is the sum of the spectral irradiance in each of the bins within this band multiplied by the (variable) bandwidth of each wavelength bin.

            statement:  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.
