Remote Sensing Phenology uses satellites to track seasonal changes in vegetation on regional, continental, and global scales. Because the most frequently used satellite sensors for monitoring phenological events have relatively large "footprints" on the land surface, they gather data about entire ecosystems or regions rather than individual species. Remote sensing phenology can reveal broad-scale phenological trends that would be difficult, if no
