 This paper assesses the latest version of the Modi's LAI-slash-FPR product, Collection 6 or C6, and compares it to other existing global LAI-slash-FPR products. It finds that the C6 product is more accurate than its predecessor, C5, with reduced root mean square error, RMSE, values ranging from 0.66 to 0.80. Additionally, the C6 product performs better than the other global LAI-slash-FPR products tested, such as Glass, Cyclopes and GOV-1. Furthermore, the C6 product shows strong agreement with other global LAI-slash-FPR products, indicating that it can be used to accurately measure LAI and FPR. Finally, the C6 product is able to capture seasonal variation in biomes, except for evergreen broadly forests, where cloud contamination causes unrealistic variations. Overall, the C6 product provides reliable biophysical information on the land surface when diagnosing climate-driven vegetation responses.
