Level 3 Data


  • Binned:Each Level-3 binned data product consists of the accumulated data for all Level-2 products, for the specified instrument and resolution, corresponding to a period of one day, 8 days, a calendar month, or a calendar year. The data are stored in a representation of a global, equal-area grid whose grid cells, or "bins," are approximately 81 km2. Each multi-file product includes a main file containing all product-level metadata and data for each bin that are common to all the binned geophysical parameters. In addition, each product includes 12 subordinate files (class = DataSubordinate), each of which contains data of one binned geophysical parameter for all bins. Subordinate files must be read in conjunction with the associated main file. L3 Binned Products Document

  • Browse:A Level-3 browse product is generated from a corresponding chlorophyll a SMI product. The main data contents of the product are a subsampled version of the SMI image array, l3m_data,stored as one byte per pixel. Each Level-3 browse product is stored in one physical HDF file.

  • SMI:The Level-3 standard mapped image (SMI) products are image representations of binned data products. Each SMI product contains one image of a geophysical parameter and is stored in one physical HDF file. Level 3 SMI Document
