Estimating GPP in China using different site-level datasets, vegetation classification and vegetation indices

Abstract Background Machine learning is widely used to estimate gross primary productivity (GPP) on large scales. Usually, models are trained at site level using eddy flux observations and remote sensing based vegetation indices. However, how to more effectively utilize the gradually increasing site...
