  2. General HDF5 File Structure for NPP Data Products Root Group <<Root>> Attributes are NPOESS General HDF_File_Root here. The All_Data group is xxx_Data contains the sensor The xxx_Product_Data populated with nested data for a given NPOESS contains a collection of A root group may xxx_Product_Data groups. data product product datasets have one or more product groups. Product groups <<H_G>> <<H_G>> <<H_DS>> <<H_G>> contain datasets HDF_xxx_Product_Data HDF_All_Data xxx_Data HDF_xxx_Product for aggregations (from NPOESS General HDF_File_Root) ... ) and individual granules. 1 The Product Granule <<H_DS>> <<H_DS>> 1...* contains a regional HDF_xxx_Product_Aggregation HDF_xxx_Product_Granule_# reference (H_RR) to (from HDF_xxx_Product) (from HDF_xxx_Product) the data. AggregateDataset : H_RO Dataset : H_RR xxx is the product type, The Product for example RDR, Aggregation contains a SDR, EDR, etc. regional object # is a number (H_RO) to the data. corresponding to the xxx is the product type, The dataset is a granule number for example RDR, regional within the aggregated SDR, EDR, etc. reference (H_RO) dataset. # is a number to the data. corresponding to the granule number within <<H_RR Array>> the aggregated The dataset is a <<H_RO Array>> DatasetArray dataset. regional AggregateDatasetArray (from HDF_xxx_Product_Granule_#) ... ) reference (H_RR) (from HDF_xxx_Product_Aggregation) ... ) to the data.
