About N2Onet
N2Onet is a global collaborative initiative to accelerate advances in N2O measurement and mitigation.
Mission: To foster and facilitate global collaboration on research advancing mechanistic understanding of agricultural soil nitrous oxide emissions, improving model representation of emissions, and increasing accuracy of nitrous oxide inventories.
Vision: To mitigate climate change through measurable and verifiable reductions in agricultural nitrous oxide emissions.
Core Members
N2Onet’s steering committee includes ASC scientists Evan DeLucia, Kaiyu Guan, Wendy Yang, and Claudia Wagner-Riddle from the University of Guelph.
Related Networks
Related research networks include CanN2Onet, SmartField, and NICCEE.
Measurement Initiatives
Through collaborative research, N2Onet has identified multiple nitrous oxide measurement priorities, including:
- Multi-scale measurements (chamber-based, eddy flux, tall tower) to gain mechanistic understanding and validate improvements in estimating N2O budgets at larger scales
- High frequency ancillary measurements, such as moisture, temperature, and soil chemistry
- Measurements of other major N fluxes in the system (e.g.., ammonia fluxes) to aid in modeling ecosystem N budgets
- Detailed agricultural management data
- Guidelines for data collection
- Curation of a repository using FAIR guidelines
Workshops and Seminars
From January 17th to January 19th (2024), The ASC convened a group of international leaders in soil nitrous oxide research in Chicago to develop a consensus vision for this new initiative and strategize about next steps. This three-day workshop helped articulate the challenges currently hindering progress and how this network could be designed to help overcome those challenges.
N2Onet is planning to host a quarterly, virtual seminar series.
In 2025, these seminars are expected in January, April, July, and October, with tentative topics of modeling advancements, CanN2Onet, SmartField, and international applications. More information to come soon!
