Terrestrial Ecosystem Science and Technology (TEST) Group (Active Archive)'s Projects
A sandbox for exploring leaf/canopy RT representations in LSMs
Tools for QA checks, fixes and post-processing for CSV files
Leaf-level Spectra-trait PLSR models to estimate key leaf traits associated with source–sink balance and carbon–nitrogen status using leaf optical properties
Small repository of example Google Earth Engine Jupyter Notebooks
A sandbox of scripts and data to explore the use of cloud-optimized geotiff datasets to facilitate direct data ingest into analysis workflows
FACE Control Program
A small repo containing GEE, rgee, and Python GEE examples
A project focused on the development of generalized spectra-trait models for the prediction of leaf photosynthetic capacity. This includes models focused on the prediction of leaf nitrogen, leaf mass per area (LMA), leaf water content (LWC), Vcmax, Jmax and dark respiration.
