Observing Changes in the Earth System
USGCRP research depends upon a comprehensive and continuous set of physical, chemical, biological, and societal observations of
global change and its impacts. Our portfolio of Earth observations includes satellite, airborne, ground-based, and ocean-based missions, platforms, and networks. Raw observations are collected remotely and in situ across Earth’s atmosphere, oceans, land, and ice using a variety of high-tech instruments, and are transformed into value-added products through data analysis and integration across time and space.
We work to sustain and strengthen the Nation’s capacity to observe Earth system changes and apply those observations to understanding the complex causes and consequences of global change. Key parts of this effort include improving the integration of observations and modeling to advance science and support decision making, and using societal, ecological, and climate observations to assess the
vulnerability of human systems and ecosystems to global change.
