What is BEPS?

The Boreal Ecosystems Productivity Simulator (BEPS) is a remote sensing approach to quantifying the terrestrial carbon cycle. BEPS uses satellite data to map the net carbon absorption rate by plants expressed as the Net Primary Productivity (NPP). BEPS has recently been expanded through the Integrated Terrestrial Ecosystem Carbon model (InTEC). Expressed as the Net Ecosystem Productivity (NEP) which quantifies the various carbon sinks and sources. The development of BEPS, its validation and application, has been the focus of a government-industry team of scientists since 1994. Research on land cover and Leaf Area Index (LAI) mapping are supporting activities to the development of BEPS. A radiative transfer model named 4-Scale has been constructed to assist in the LAI algorithm definitions and in radiation calculations within BEPS. A ground-based optical instrument named TRAC has also been developed for quick and accurate measurements of LAI.

Why do we do this research?

Terrestrial ecosystems are an important part of the climate system. Their role in climate change, and in the global carbon cycle is not well understood. Satellite remote sensing, coupled with numerical models provide the unique tools for monitoring the spatial and temporal dynamics of ecosystems and for quantifying their role in climate change. Our work also results in the highly synthesized information needed for sustainable management of natural resources.
