Below is the generic header for subset data files prepared by ORNL:

HDFname,Product,Date,Site,ProcessDate,Band,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25, 26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49

where

• HDFname - string of fields separated by "periods"
  (e.g.,
  "MOD13A2.A2000305.fn_uswipark_01.003.2001275225112.1_km_16_days_EVI")
• HDFname subfields:
  o MODIS product shortname (MOD13A2)
  o Satellite (A=AM or Terra) and date of satellite overpass (yyyyddd)
  o FLUXNET site name (fn_uswipark_01)
  o Product version (003)
  o Processing date (yyyydddhhmmss)
  o Band (e.g., "1_km_16_days_EVI")
• Product - MODIS product shortname (MOD13A2)
• Date - Satellite (A=AM or Terra) and date of satellite overpass (yyyyddd)
• Site - FLUXNET site name (fn_uswipark_01)
• ProcessDate - Processing date (yyyydddhhmmss)
• Band - ("1_km_16_days_EVI", "1_km_16_days_EVI_Quality", "1_km_16_days_NDVI", "1_km_16_days_NDVI_Quality")
• 1-49 - values for 49 pixels

Note: In Excel, the ProcessDate column should be formatted to "number" with 0 decimal places to make sense, and QC rows should also be formatted to "number" with 0 decimal places to see the bit pattern for QC flags.

Each row has 49 data values that follow a 4th-quadrant organization with cell 1 representing the northwest-most (UL) corner and cell 7 the northeast-most (UR) corner of the top row. Based on geographic coordinates submitted, cell/column 25 will contain the field site or flux tower.

Note: The ORNL DAAC may receive several data files representing a single acquisition date for a site. The presence of duplicate files indicates that the data was reprocessed by MODAPS. The ASCII tables provided by the ORNL DAAC include only the data with the most recent processing date/time.
