File Format Basics

Filled Land Surface Albedo Product files are stored in Hierarchical Data Format (HDF). HDF is a multi-object file format for sharing scientific data in multi-platform distributed environments. HDF files should only be accessed through HDF library subroutine and function calls, which can be downloaded from the HDF web site. All of the parameters are stored as Scientific Data Sets (SDS's) within the HDF file. A total of 38 files are produced per sixteen-day data period.

File Frequency and Maximum File Size

  • 20 Filled Land Surface Albedo Map Product Files/Period (1 per each of 10 wavelengths for both white- and black-sky albedo) ~445MB
  • 10 Filled Land Surface Albedo Map Run-Time Processing QA Files/Period (each file applies to both white- and black-sky albedo) ~445MB
  • 1 MOD43B3 General QA File/Period (applies to both white- and black-sky albedo) ~445MB
  • 7 MOD43B3 Band Specific QA Files/Period (applies to both white- and black-sky albedo) ~223MB
