eLUE-GPP (MODIS): A global gross primary productivity product based on ecosystem light-use-efficiency model and MODIS EVI

Gross Primary Productivity (GPP) represents the cumulative amount of carbon dioxide (CO2) assimilated by green plants through photosynthesis at specific time intervals and spatial scales. It is the main component of the carbon exchange between the terrestrial biosphere and the atmosphere, and has a major influence on global climate and terrestrial ecosystem functioning. Over the last two decades, the continuous and reliable collection of global land surface variables by EOS-MODIS, and the parallel development of the eddy-covariance flux tower network (FLUXNET) have enabled the integration of MODIS observations with tower measurements for the calibration and validation of remote sensing models to obtain global GPP estimates. Despite the significant progress and success to date, current remote sensing GPP models based on the light use efficiency (LUE) concept share several limitations, including the difficulty in accurately predicting LUE variability and the associated use of land cover m..., The eLUE Gross Primary Productivity (eLUE-GPP) is based on a simple yet ecologically sound ecosystem light use efficiency (eLUE) GPP model, using the more than two decades of global MODIS Enhanced Vegetation Index (EVI) product and the publicly available FLUXDATA2015 dataset, to generate a global GPP product (eLUE-GPP) from February 2000 to March 2024. The eLUE-GPP is available in both global and site scales and at various temporal and spatial resolutions. , , # eLUE-GPP (MODIS): A Global Gross Primary Productivity Product based on ecosystem light-use-efficiency model and MODIS EVI

The eLUE Gross Primary Productivity (eLUE-GPP) is based on a simple yet ecologically sound ecosystem light use efficiency (eLUE) GPP model, using the more than two decades of global MODIS Enhanced Vegetation Index (EVI) product and the publicly available FLUXDATA2015 dataset, to generate a global GPP product (eLUE-GPP) from February 2000 to March 2024. The eLUE-GPP is available in both global and site scales and at various temporal and spatial resolutions.

## Description of the data and file structure

The eLUE-GPP product has two Science Datasets, comprising GPP and GPP uncertainty. To reduce data storage size, the original values have been adjusted to integers. Users are advised to refer to the scaling factors for value restoration when using the data.

The eLUE-GPP dataset prov...
