Terrestrial Sciences Section

Who We Are

The Terrestrial Sciences Section (TSS) is part of CGD at the NSF National Center for Atmospheric Research (NCAR) in Boulder, Colorado. TSS consists of a diverse group of researchers who explore topics related to the land surface. This involves the development of models and use of observations to support Earth systems research of natural and managed terrestrial ecosystems through improving scientific understanding of the carbon, water, and nutrient cycles, land use and land cover change, land-atmosphere interactions, and model uncertainty.

Researchers in TSS develop and use appropriate multiscale models of varying complexity, utilizing remote sensing, advanced analytical techniques, and observations to study the role of the terrestrial biosphere in the Earth system. Section members are involved in developing the land/vegetation model used in the Community Earth System Model (CESM). This model, the Community Land Model (CLM), includes biogeophysics, biogeochemistry (carbon, nitrogen, dust, volatile organic compounds), hydrology, disturbance, land use, agriculture, and vegetation dynamics.

Much of the research conducted in our section and the knowledge generated from work in our lab informs our understanding of past, current, and future ecosystems and human landscapes with support for suitable (effective/efficient) and safe responses, including nature-based solutions for mitigation and intervention, as well as actionable science initiatives related to management, adaptation, and resilience in human and Earth systems. TSS provides a focal point for CGD and university ecological and hydrological research and serves as a resource to these communities in the use of CESM. A growing body of research in TSS is engaging with (and sponsored by) stakeholder communities, including water resources, forestry and wildfire hazards, agriculture, and fisheries, among others, to respond to their environmental concerns.

Our Mission

To advance scientific understanding of the role of the terrestrial system and related human activities in the Earth system through research, education, and outreach, while working in a collaborative and interdisciplinary environment.

Specific Goals

• Develop state-of-the-art models and tools, combined with novel use of observations to study the exchanges of energy, momentum, and materials between the land and the atmosphere, hydrosphere, cryosphere and oceans.
• Understand the impacts of Earth System change on the terrestrial system, including changes in vegetation, hydrology, and biogeochemistry.
• Coproduce and communicate the results of our research to policymakers, stakeholders, and the public to provide society with the knowledge needed to mitigate and adapt to change.
• Develop and offer training and tutorials for research tools that enhance and support the broader community of researchers.
