Description of Data Fields
--------------------------------

DataField_1
Data Field Name:        BYTE BRDF_Albedo_Band_Mandatory_Quality_Band1("YDim","XDim")

Description:            BRDF Albedo Mandatory Quality for band 1 


Data conversions:
       Mandatory QA    0 = processed, good quality (full BRDF inversions)    
                       1 = processed, see other QA (magnitude BRDF inversions)
                       255 = Fill Value

Data Field Attributes:

Name:               Type:          Num_Val:    Source:    Value:

long_name                   HDF-STRING  1           Code  "BRDF_Albedo_Band_Mandatory_Quality_Band1"
units                       HDF-STRING  1           Code

_FillValue                  HDF-uint8   1           Code        255

------------------------------------------------------------------------

Data_Field_2 .... Data_Field_8  BRDF Albedo Mandatory Quality for Band 2-7 and VIS

Data conversions:
       Mandatory QA    0 = processed, good quality (full BRDF inversions)    
                       1 = processed, see other QA (magnitude BRDF inversions)
                       255 = Fill Value


------------------------------------------------------------------------
Data_Field_9 .... Data_Field_10  BRDF Albedo Mandatory Quality for NIR and and shortwave Broadbands 

Data conversions:
       Mandatory QA    0 = processed, good quality (full BRDF inversions)    
                       1 = processed, see other QA (magnitude BRDF inversions)
					   2 = processed, good quality (full BRDF inversions, Band6 is fill value due to non-functional or noisy detectors)
					   3 = processed, see other QA (magnitude BRDF inversions, Band6 is fill value due to non-functional or noisy detectors)
                       255 = Fill Value

					   
Note: The Narrow-to-Broadband coefficients without Band6 are applied if only Band6 
      is fill value due to non-functional or noisy detectors and the other bands are 
	  valid full or magnitude retrievals. Mandatory QA “2” is assigned if the other bands 
	  are all full inversions and Mandatory QA “3” is assigned if one or more of the other bands 
	  are magnitude inversions.
