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

<p>The <strong>NI-LUE GPP</strong>&nbsp;with 0.05&deg; 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&nbsp;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>.</p> <p>Period: 2001-2018</p> <p>Spatial resolution: 0.05&deg;</p> <p>Temporal resolution: 8 days</p> <p>Projection: geographic latitude/longitude</p> <p>Data format: Tiff</p> <p>Upper left coordinates: -180&deg;E, 90&deg;N</p> <p>Scale factor: 1000</p> <p>Unit: gCm-2d-1</p>
