The SORCE solar spectral irradiance data products are written using the
NCSA HDF5 file format. HDF5
is a heirarchical data format which consists of two object types:
groups and datasets. Groups are analogous to directories or folders (all
files have at least a root or "/" group), whereas datasets may
contain arrays, images or tables. Both object types may contain a set of
attributes. HDF5 files are portable, that is one can read the data using the
HDF5 libraries or tools on any supported platform (Windows, MacOS, Linux, or
Unix) independent of where the file was originally created.
Each SORCE Level 3 Solar Spectral Irradiance file contains a set of file level
attributes and four data tables: "Solar Spectral Irradiance",
"Solar and Geophysical Parameters" "Total Solar Irradiance",
and "XPS EUV Solar Spectrum". Each table has a set of attributes as
well which contain the definition of each field in the table. The structure or
layout of the data files is shown here:
