Figure S3. Yearly Measurements of observed measurements of NEE and Neural Network output (a) Half-hourly NEE output data represented in red by our direct observations, data in blue were direct observations removed to validate neural network model, data in gray depict neural network modeled NEE yearly data. (b) Removed Dataset Validation (R2=0.78) in model performance. (c) Whole dataset performance validation (R2 = 0.81).
