 The Modi's Collection 6, C6 data set was compared to its predecessor, Modi's Collection 5, C5, to evaluate the accuracy and consistency of the data. It was found that the C6 data set had better agreement with the C5 data set than expected given the difference in spatial resolution. Additionally, the improvements made to the algorithm inputs resulted in higher accuracy for LAI and FPR measurements. This article was authored by Kai Yan, Tae Jin Park, Wang Jin Yan, and others.
