How is Earth changing and what are the consequences for life on Earth? This question drives Terra science in each of NASA's six broad focus areas:
- climate variability and change
- atmospheric composition
- carbon cycle and ecosystems
- water and energy cycle
- Earth surface and interior
Science results based on Terra data have been published in thousands of peer-reviewed articles---6,400 by the end of 2011. See publications to search journal articles that cite Terra data.
