fLUE

This dataset contains fLUE data as described in Stocker et al., (2018) <em>New Phytologist</em>. fLUE is derived from the FLUXNET 2015 dataset, Tier 1, daily. Only sites are included where the method for quantifying fLUE satisfied performance criteria (see Stocker et al. 2018). <em>site</em>: Site name (ID) from the FLUXNET network <em>date</em>: DD/MM/YY year: year <em>doy</em>: day of year <em>fLUE</em>: unitless, fraction of actual over potential light use efficiency, derived from artificial neural networks. This quantifies the fractional reduction in light use efficiency due to soil moisture (1 = no reduction). <em>is_flue_drought</em>: TRUE if the data is identified as a 'drought' based on deviation of fLUE from 1 (see Stocker et al., 2018) <em>cluster</em>: sites are assigned to clusters based on their typical parallel evolution of greenness and fLUE throughout drought events. cDD: 'drought deciduous', cGR: 'evergreen', cLS: 'low sensitivity', cNA: 'not affected'.
