The Numerical Terradynamic Simulation Group (NTSG) is a research center in the University of Montana's W.A. Franke College of Forestry & Conservation pioneering new approaches for landscape ecological and hydrological studies. A major focus of our research is to understand how vegetation responds to climate variability and influences the water, carbon and energy cycles. NTSG conducts research over a broad range of spatial scales, emphasizing emerging technologies in satellite remote sensing, computational modeling and biophysical theory. We are a leader in the development and application of satellite remote sensing for global environmental assessment and monitoring. NTSG is a NASA Earth Science Information Partner (ESIP), developer and repository for a variety of global land data products from satellite Earth missions, including MODIS (MOD16/17) vegetation productivity and evapotranspiration, AMSR land parameters, and SMAP (L4C) carbon flux products.
