AB  - The photosynthetic light use efficiency (LUE) is used to estimate the rate of photosynthesis in green vegetation. LUE is generally defined as the carbon uptake divided by absorbed photosynthetically active radiation (PAR). Several proxies for LUE estimation from remotely sensed data have been introduced, while the most promising results have been achieved by the Photochemical Reflectance Index (PRI) and chlorophyll fluorescence (ChlF). Both PRI and ChlF can serve as a proxy for photosynthetic do...
