| Abstract | For previous land cover input, use MOD12Q1 from LPDAAC instead of MOD12Q1 from MODAPS. |
| Problem Statement | Use of incorrect version of previous land cover inputs. Use of the productionversion of MOD12Q1 containing multi-year data (2001-2003) resulted in invalidvalues in the land cover product. The PGE was designed to use the official version of MOD12Q1 containing only one year of data. |

| Data Granules to be Used for Science Testing | Test the failed cases. |
| Justification | Remove invalid values in the land cover product and produce expected results. |
