Ammonia Concentration and Deposition Data from Whim Bog Nitrogen Experiment

An NH3 enhancement experiment established in 2002 provides ammonia concentration and deposition rates from a Scottish ombrotrophic bog. Data includes monthly passive sampler measurements and modelled deposition rates using a unidirectional resistance model. The work was supported by the UK-SCAPE programme.

Use Cases

• Model ammonia deposition rates using the unidirectional resistance model based on measured NH3 concentrations and micrometeorology.
• Analyze temporal trends in monthly passive sampler NH3 concentration data from the 2002-2022 experimental period.
• Study the impact of controlled NH3 releases on downwind monitoring transect concentration levels under suitable wind conditions.
• Correlate modelled deposition rates with environmental conditions at the Whim Bog, Scotland field site.

Strengths

• Data originates from a long-term experiment established in 2002, providing over two decades of temporal coverage.
• Measurements are derived from a controlled field release setup at a specific ombrotrophic bog site near Edinburgh, UK.
• Deposition rates are calculated using a modelled methodology (unidirectional resistance model) based on direct measurements.

Limitations

• Specific data volume (row count, column count) and sample details are unavailable for assessment.
• Data is geographically limited to a single experimental site (Whim Bog, Scotland), limiting broad spatial analysis.
• The reliance on modelled deposition rates introduces methodological assumptions that may affect accuracy.
