USA National Phenology Network
Integrating phenology data across spatial and temporal scales
![Page 2: Jake F. Weltzin United States Geological Survey USA National Phenology Network Integrating phenology data across spatial and temporal scales](https://reader031.vdocument.in/reader031/viewer/2022032722/56649f505503460f94c72b10/html5/thumbnails/2.jpg)
A new data resource—a national network of integrated phenological observations across
space and time
Key Goal
Understand how plants, animals and landscapes respond to environmental variation and climate change
![Page 3: Jake F. Weltzin United States Geological Survey USA National Phenology Network Integrating phenology data across spatial and temporal scales](https://reader031.vdocument.in/reader031/viewer/2022032722/56649f505503460f94c72b10/html5/thumbnails/3.jpg)
• Create a scientifically based phenology network with broad participation
• Create and maintain a national phenology information management system
• Develop and promote standardized monitoring protocols
• Integrate observations of plants, animals & landscapes across space & time
• Create decision support tools for application of phenology data
Core functions

• National-scale science and monitoring initiative
• Agencies, NGOs, academia, the public
• Integrates with other science/monitoring networks
• Target: 100,000 observation locations
• Plants + animals; contemporary + legacy data
• Education & outreach
• Integration across spatial and temporal scales
NPN in a nutshell

• We are live today!• We are a distributed, bottoms-up national network• Broad variety of users/audiences• Business to business AND business to consumer• Large number of contributing stations• Multiple charges: education/outreach, research,
decision-support• Interaction with other large networks (CEN, NCCRC,
NPS I & M, … )• Focus
Key challenges to data integration
What we are…

• Incredibly complex nature of the data (not rainfall!)• real-time (contemporary)• repeated (different variables through time)• one-off, or multiple observers• dynamic standard protocols• customization of methodologies• images
• Discovery and ingestion of legacy datasets• large, un-digitized, simple (data rich)• small, complex (metadata rich)

• Metadata standards • Integration of contemporary and legacy phenology datasets• Integration of external supporting data• Web services
• Internal (visualization, synthesis products)• External users)
• Scaling (organismal to digital number)• Provenance• QA/QC of all data• Long-term nature of data (curation)• Security
