Short Description Flag dead and noisy detectors in band 5 and 6 of Aqua and the detector 3 in band 5 of Terra.
Long Description This update to the PGE contains fix in the source code to flag the detectors in the 500m Surface Reflectance Band QA SDS of the L2 MOD09 product. The flags are propogated from the input L1B product. Source code fix includes
Fix to flag a single detector (detector 3) in band 5 of Terra as good.
Fix to flag dead detectors in band 5 and 6 of Aqua correctly as flagged in the metadata of L1B. None of the detectors in Aqua was being flagged as dead by the earlier version of the PGE.
Fix in the cloud shadow algorithm to check for the fill values in band31, resulting in minor differennce in cloud shadow for these pixels only.
