Climate change is changing the health and distribution of plants around the world. Scientists use various satellite and airborne systems to monitor vegetation changes over space and time. However, these systems have low resolution. This limits their use in identifying fine-scale patterns and properties of plants. This problem is especially great in the Arctic, where vegetation is more mixed than in other ecosystems. Scientists recently adopted unoccupied aerial systems (UASs) for high-resolution monitoring of changes in vegetation through the Next Generation Ecosystem Experiment (NGEE)-Arctic. UASs provide high-resolution data on vegetation that improves scientists’ understanding of how plants respond to the environment. These data help scientists better predict how climate change affects ecosystems on Earth.
