USA National Phenology Network Observational Data Documentation

The goals of the USA National Phenology Network (USA-NPN) are to
advance science, inform decisions, and communicate and connect with the public regarding phenology
and species’ responses to environmental variation and climate change. The USA-NPN seeks to advance
the science of phenology and facilitate ecosystem stewardship by providing phenological information
freely and openly. To accomplish these goals, the USA-NPN National Coordinating Office (NCO)
delivers observational data on plant and animal phenology in several formats, including minimally
processed status and intensity datasets and derived phenometrics for individual plants, sites, and
regions. This document describes the suite of observational data products delivered by the USA
National Phenology Network, covering the period 2009–present for the United States and accessible via
the Phenology Observation Portal and via an Application
Programming Interface. The data described here have been used in diverse research and management
applications, including over 30 publications in fields such as remote sensing, plant evolution, and
resource management.
