The Numerical Terradynamic Simulation Group (NTSG) is a research laboratory at The University of Montana in Missoula pioneering new approaches for landscape ecological and hydrological analyses. The primary focus of NTSG is to understand how terrestrial vegetation responds to climate variability and influences energy, water and carbon cycles. NTSG conducts research over a broad range of spatial scales from individual landscape units to basin, continental and global domains. NTSG has strong emphasis in the application of ecological theory and environmental analysis using computational process modeling, satellite remote sensing and GIS. NTSG is a NASA Earth Science Information Partner (ESIP) and is involved with the NASA Earth Observing System as a repository for a variety of global land data products, including MODIS (MOD17) vegetation productivity.
