A global gross primary productivity product considering canopy nitrogen concentrations and multiple environmental factors from 2001 to 2018

The <strong>NI-LUE GPP</strong> with 0.05° spatial resolution and at 8 days interval from 2001 to 2018 was generated based on an improved light use efficiency (LUE) model that simultaneously considered temperature, water, atmospheric CO₂ concentrations, radiation components, and nitrogen (N) index. In the model, a vegetation index capable of characterizing canopy N concentrations was selected to achieve dynamic mixmum LUE. In addition, global optimum temperature distributions mapped based on satellite-retrieved SIF were introduced to calculate the temperature stress factor. This dataset includes<strong> global GPP product</strong> and its <strong>uncertainty data</strong>. Period: 2001-2018 Spatial resolution: 0.05° Temporal resolution: 8 days Projection: geographic latitude/longitude Data format: Tiff Upper left coordinates: -180°E, 90°N Scale factor: 1000 Unit: gCm-2d-1
