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 December 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 December 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.

总初级生产力（Gross Primary Productivity, GPP）指绿色植物在特定时间间隔与空间尺度下，通过光合作用同化的二氧化碳（CO₂）累积总量。它是陆地生物圈与大气之间碳交换的核心组成部分，对全球气候及陆地生态系统功能具有关键性影响。
近二十年来，地球观测系统-中分辨率成像光谱仪（EOS-MODIS）持续可靠地采集全球陆面变量数据，同时涡度协方差通量塔网络（FLUXNET）得到快速发展，这使得研究者得以将MODIS观测数据与通量塔实测数据相结合，用于遥感模型的校准与验证，进而生成全球GPP估算产品。尽管目前已取得显著进展与成果，但现有基于光能利用率（Light Use Efficiency, LUE）理念的遥感GPP模型仍存在诸多局限，例如难以精准预测光能利用率的变异特征，以及对土地覆盖数据的相关依赖等……
本数据集eLUE总初级生产力（eLUE-GPP）基于一款简洁且符合生态学原理的生态系统光能利用率（eLUE）GPP模型，利用二十余年的全球MODIS增强型植被指数（Enhanced Vegetation Index, EVI）产品与公开可用的FLUXDATA2015数据集，生成了2000年2月至2024年12月的全球GPP产品（eLUE-GPP）。该产品同时支持全球尺度与站点尺度的数据应用，且具备多种时空分辨率。
