Modelled canopy nitrogen concentration calibrated with NEON plant foliar chemistry observations and predicted with L1 surface directional reflectance, derived from the NEON Imaging Spectrometer (NIS). Bands include 1) canopy nitrogen percent, 2) canopy nitrogen model uncertainty, 3) classification result for needle vs. non-needle model and …
Total nitrogen at soil depths of 0-20 cm and 20-50 cm, predicted mean and standard deviation. Pixel values must be back-transformed with exp(x/100)-1. In areas of dense jungle (generally over central Africa), model accuracy is low and therefore artifacts such as banding (striping) might be …
