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
"concatenated flags"
valid_range HDF-uint8 2 Code 0, 254
_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.
