Terrestrial Ecosystem Science & Technology

Mission

The Terrestrial Ecosystem Science and Technology (TEST) group seeks to improve the representation of ecosystem processes in Earth System Models in order to increase our ability to understand and project global change.  We study processes that have a global impact on climate, and focus on ecosystems that are poorly understood, sensitive to global change, and inadequately represented in models.

Approach

  • Develop and use novel computational methods to quantify model sensitivity and target critical areas where improved process knowledge will reduce model uncertainty.
  • Use state-of-the-art techniques - including remote sensing- to advance mechanistic understanding and enable scaling of key ecosystem processes.
  • Test and inform models iteratively through measurements and environmental manipulations

Goal

Advance process level understanding of terrestrial ecosystems, incorporate new knowledge into models, reduce model uncertainty - and ultimately - improve our ability to understand and project global change.

NGEE

Next Generation Ecosystem Experiments - Arctic

The NGEE-Arctic project is a collaboration among scientists at Oak Ridge National Laboratory, Los Alamos National Laboratory, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, University of Alaska Fairbanks. The aim of the project is to develop a process-rich ecosystem model, in which the evolution of Arctic ecosystems in a changing climate can be modeled at the scale of a grid cell in a high resolution Earth System Model.  Work at Brookhaven is focused on Vegetation Dynamics.

FACE

Global Change Experimental Facility Design and Management 

The TEST group is an internationally recognized leader in the development of Free Air CO2 Enrichment (FACE) research facilities. We are interested in the design and management of manipulative experiments that examine the effects of carbon dioxide, ozone, other atmospheric pollutants, temperature and precipitation on natural and managed ecosystems.
