Remote Sensing Phenology

Sioux Falls, South Dakota - United States

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 not impossible, to detect from the ground. And, because data collection by satellite sensors can be standardized, the data are reliably objective. Remotely sensed phenological data are useful for assessing crop conditions, drought severity, and wildfire risk as well as tracking invasive species, infectious diseases, and insect pests. Because phenological events are sensitive to climate variation, these data also represent a powerful tool for documenting phenological trends over time and detecting the impacts of climate change on ecosystems at multiple scales.

North American Bird Phenology Program
United States

Phenology is the study of recurring plant and animal life cycle stages, or phenophases, such as leafing and flowering of plants, maturation of agricultural crops, emergence of insects, and migration of birds. Many of these events are sensitive to climatic variation and change, and are simple to observe and record. The North American Bird Phenology Program, part of the USA-National Phenology Network, was a network of volunteer observers who rec

The Northeast Regional Phenology Network (NE-RPN) is a cooperative network designed to coordinate phenological monitoring, facilitate data sharing and synthesize phenology data from the northeastern US and eastern Canada. We encourage the partcipation of researchers and citizen scientists alike. NE-RPN is an affiliate of the USA National Phenology Network (USA-NPN).

United States

Phenology is a segment of ecology focusing on the study of periodic plant and animal life-cycle events that are influenced by climate and seasonal change in the environment. Skunks emerging from winter dens, sandhill cranes trumpeting their return, and seeds ripening are all examples of annual phenological events. Phenology is derived from the Greek word phaino meaning to show or appear, indicating its principal concern with the dates of first oc
