 The Modi's collection 6, C6, LAI and FPR products have been released since August 2015, replacing the previous version, Collection 5 or C5. These products were compared to evaluate their accuracy, uncertainty, and consistency. It was found that the C6 products had better agreement with the C5 products than the C5 products did with the C4 products. Additionally, the C6 products showed improved agreement with the C5 products when using the same biomes as inputs. Furthermore, the improvements made to the algorithms used in the C6 products resulted in higher accuracy and lower uncertainty. Finally, it was found that the spatial scale effects caused by a resolution change from 1 km to 500 m did not significantly affect the results.
