The biogeophysical focus group has proposed to revisit the LAI protocol released in 2014 to meet updated GCOS requirements and also include fAPAR and FCover variables. Originally designed around the 500 m MODIS resolution, the LAI protocol should now be adapted to higher-resolution data (e.g. from Sentinel and Landsat) with a renewed focus on advancing technologies (mainly UAV) and uncertainty characterisation. A draft update to the protocol is underway with the initial step being a scientific review paper for submission to RSE in Q2 2026.
