Global horizontal spectral irradiance in Albuquerque - Metadata

The Photovoltaic Systems Evaluation Laboratory (PSEL) at Sandia National Laboratories (SNL) in Albuquerque, NM has measured global horizontal spectral irradiance nearly continuously from September 2019 to March 2022. During this time other broadband irradiance measurements (global horizontal, direct normal, diffuse horizontal and global normal) and weather variables were also recorded. For this dataset PV Performance Labs (PVPL) has pulled together data from both sources to assemble a calendar year spectral data set for use in photovoltaic research. It is composed of twelve segments of 15 days each, beginning with January 1-15 and ending with December 1-15. The segments are all taken from the two-year period October 2019 to September 2021.

The data set and creation process are described in further detail in the following Sandia report:

• A. Driesse, M. Theristis and J. S. Stein "Global horizontal spectral irradiance and module spectral response measurements: an open dataset for PV research," Sandia Report No. SAND2023-02045.

Please cite this report if you use the data.

And finally, we encourage you to let us know how the data set is useful (or not), and to send us comments and suggestions for making this data set (or upcoming ones) even better.

Note, a similar set of global normal spectra is found here.
