This repository contains code and data employed to generate a set of reference maps of soil phosphorus (P) for the pan-Amazon region. The primary intent of these maps is to provide reference data for parametrization and benchmark of Land Surface/Terrestrial Ecosystem models. The maps created are the mean prediction of a set of random forest regression models fitted with available observed in situ data found in scientific literature. The model predictions are generated based on data from geographic datasets that have the same features utilized to fit the models.
