PCR Number	PCR06-023
PGE Number	PGE23
PGE Version	5.0.10
Affected Product	L3 16-day BRDF (MCD43)
Short Description	Fix a bug resulting in more cases of zero values for two of three albedo parameters.
Long Description	A source code bug in the previous version of the PGE may have caused too much constraint on the retrieved BRDF parameters if one of the fully retrieved parameter was negative. The new version of the PGE contains a bug fix for the problem and includes a code change to do the magnitude inversion if only isotropic parameter is retrieved from the full inversion.
Affected Products downstream	None.
Effective Data Acquistion Date	Terra C5 Reprocessing 2000312
Comment/Caution	We may see several percent of difference in 7 MODIS land band parameters and a little more in broadband. However, the difference in albedo values are expeted very minor.
