Middleton, E. M., et al. "Photosynthetic efficiency of northern forest ecosystems using a MODIS-derived Photochemical Reflectance Index (PRI)." Remote Sensing of Environment 187 (2016): 345-366.

This paper linked PRI from MODIS and daily LUE from flux tower, and analyzed how observation angle and ecosystem types influence relationships between PRI and LUE.

I really don't understand how could we link instantaneous PRI measurement with daily integrated LUE.

I don't agree.
