Thank you.

So. Science Paper (SP) uses data from 2 spaceborne sensors, MODIS and AVHRR.

Nature Paper (NP) uses data from AVHRR alongside 3 other metrics: GLASS, GLOBMAP, and TCDR, all of which claim to be fusions of the same data from MODIS and AVHRR. (https://www.mdpi.com/2072-4292/8/3/263 ... https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/201... ... https://zenodo.org/records/4700264 )

NP supplementals show the data from AVHRR does trend upwards to the present data (agreeing with SP), but the other 3 metrics are trending flat (GLASS, TCDR) or downward (GLOBMAP).

I have neither the expertise nor inclination to delve further into the various methodologies of creating these various Leaf Area Indices.
