Scientists have released a comprehensive database featuring 40,000 ammonia flux measurement records collected between 1991 and 2024. This standardized dataset aims to reduce uncertainty in nitrogen exchange research across diverse global ecosystems.
Why it matters
The global scarcity of reliable ammonia exchange measurements has historically created significant uncertainty in nitrogen budget assessments. This harmonized data will facilitate the validation and calibration of essential ammonia exchange schemes.
The database contains 40,000 quality-controlled ammonia flux records covering the years 1991 to 2024. The measurements were processed using consistent algorithms and stability correction functions to ensure data uniformity across varied ecosystems.
The players
Analysis Team in Braunschweig
This group of researchers led the effort to harmonize and quality-control the vast collection of flux measurements.
Research Groups in Budapest and Szeged
These teams collaborated on the scientific efforts to standardize the ammonia exchange data.
The details
The dataset includes diverse environments ranging from forests and grasslands to croplands and dunes, reflecting varied ambient ammonia and sulphur dioxide concentrations. A significant share of the measurements originates from the Netherlands, providing a robust foundation for biosphere-atmosphere exchange analysis.
Timeline
The data collection period spanned from 1991 to 2024.
The ammonia database was officially published on October 7, 2026.
The Big Picture
This database extends the nitrogen flux monitoring established by the European Monitoring and Evaluation Programme nitrogen deposition network. By providing a unified record, it helps bridge the gap between fragmented local field studies and continental-scale nitrogen models.
Improved nitrogen budget assessments will lead to more accurate environmental policies and better-calibrated models for climate change. This data allows scientists to track how ammonia behaves in environments ranging from peatlands to croplands.
The takeaway
The unification of 40,000 flux records creates a new standard for atmospheric research that was previously impossible to achieve. Researchers can now utilize this benchmark to refine their understanding of how ammonia moves between the Earth's surface and the atmosphere.
