Appendix-C File organization

The AORadFlux file are formatted to conform with the standard defined in the EOSDIS Version 0 Data Product Implementation Guidelines (Draft Version 1.0). For most users, knowledge of the HDF SD interface is sufficient to read and use metadata and scientific data sets. For compatibility with Version 0 standards and with tools in development, the data are organized as a single HDF Vgroup with the name"Gridded Monthly Arctic Radiative Fluxes calculated from the C2 data set. . In this Vgroup are included the HDF Vdata for the metadata attributes, the Vdata for the scientific data sets and a Vdata with class "Geometry" and name "EASE GRID" that describe the projection and grid parameters for this grid. This Vdata contains the following information:M

These parameters correspond to the parameters used by a set of gridding and projection programs used for creating the EASE grid standard at NSIDC.
