Abstract PGE23 v6.0.31. Removed 3 datasets from MCD43A4: Mandatory_Band_Quality_Band_vis/nir/short wave
Problem Statement MCD43A4 contains three additional band QA datasets (for vis, nir and shortwave) that aren't expected. Seven band QAs are expected in the file corresponding the seven land bands (band 1 - 7) for which NBAR is reported in the product file. Product from the operational version 6.0.29 contains 10 QA datasets.
Description of Change Changes to PGE23 to remove the three unwanted additional QA datasets.
Products Affected MCD43A4
Software Affected PGE23 v6.0.31
Processing String to Receive the Change Terra Reprocessing, Aqua Reprocessing
Downstream Product Effects None.
Data Granules to be Used for Science Testing Process 4 global data days starting with the data day 2008201 generating the BRDF-Albedo product for all land tiles with and without the code change.2010-059
Justification No change or improvement to any of the product suite except for reduced file size from removal of the three unwanted QA datasets in MCD43A4. No reprocessing is required. .
Effective Date for Implementation of Change Completed.
