The USA National Phenology Network (USA-NPN) is a continental-scale network of standardized, routine, and sustained phenological observations for plants and animals, and the tools to analyze them at local to national scales (www.usapnpn.org). In operation since 2007, USA-NPN collects, organizes, and delivers research-grade phenological data, information, and forecasts to advance global change research; inform natural resource policy and management; and promote understanding of phenology by a wide range of audiences. The USA-NPN team is based at the University of Arizona and includes Theresa Crimmins, Nathan Acosta, Samantha Brewer, Ellen Denny, Erin Posthumus, Alyssa Rosemartin, and Jeff Switzer. The USA-NPN team epitomizes the spirit of the AGU Science and Society Section Team Award. The team has a long and deep record of scientific and societal impact across scales. It is dedicated to inclusion and equitability in their data, collaborations, and operation, while fully embracing the tenets of knowledge coproduction, where partner needs dictate the format, frequency, and lead time of product delivery.
Citizen science data are often criticized for a lack of reliability or unevenness in observations, but the work of the USA-NPN team to create, maintain, and communicate standardized protocols for observations, data curation, data access, and synthesis into national- scale products makes USA-NPN an uncommonly robust network compared to many crowd- sourced citizen science endeavors. USA-NPN’s citizen science platform, Nature’s Notebook (https://www.naturesnotebook.org), is used routinely by tens of thousands of citizens and professionals across the United States. Observations enabled by Nature’s Notebook now exceed 34M records for more than 1,750 plant and animal species and is growing by approximately 4M records each year. The USA-NPN team has created tools for downloading, visualizing, and synthesizing phenological data, enabling access and use by a wide breadth of users. USA-NPN programs are described in more than 40 publications, and USA-NPN data have been used in 40 Ph.D. and M.S. theses and more than 175 scientific publications. NPN protocols, products, and tools have been adopted by instructors at more than 100 higher education institutions and more than 100 teachers in K–12. USA-NPN maps and results reach millions of citizens through the news media each year. The USA-NPN team has helped invigorate a rebirth of phenological monitoring as a critical element of citizen science and global change research, assessment, and adaptation. I cannot imagine a more impactful and deserving recipient of the Science for Society Section Team Award than the USA-NPN team.
