About Us

The Numerical Terradynamic Simulation Group (NTSG) is 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 ecological 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.
