Data and Models
SAGE aims to improve our understanding of the global environment, and how it is being affected by human activities. To achieve this goal, we have been developing maps, computer models and datasets to describe the behavior of Earth's terrestrial ecosystems, hydrological systems, and climate. We have developed global ecosystem (IBIS) and terrestrial hydrology (THMB) models, as well as fully coupled climate-vegetation models (GENESIS-IBIS and CCM3-IBIS). In addition, we have created new datasets of global ecosystems, historial land use, and land cover change, and datasets specific to the Amazon Basin. You may freely download any of these items.
