Ammonia Concentration and Deposition Rates from Tropical Forest Experiment, Sri Lanka 2022

Environmental Information Data Centre provides meteorological data and ammonia concentration and deposition rates from an NH3 enhancement experiment in a tropical forest in central Sri Lanka. The dataset includes multi-height meteorological measurements, monthly passive sampler NH3 concentration readings, and modeled deposition rates using a bi-directional resistance model. The work was supported by UKRI GCRF South Asian Nitrogen Hub.

Use Cases

• Model ammonia deposition rates using the bi-directional resistance model based on measured NH3 concentrations and micrometeorology.
• Analyze the relationship between multi-height meteorological measurements and monthly passive sampler NH3 concentration readings.
• Study the impact of controlled NH3 release under suitable wind conditions on downwind monitoring transects.
• Calibrate high temporal resolution NH3 concentration measurements against target enhancement concentrations.

Strengths

• Data originates from a controlled NH3 enhancement experiment with a full suite of multi-height meteorological measurements.
• Includes both measured NH3 concentrations and modeled deposition rates using a bi-directional resistance model.
• Supported by UKRI GCRF South Asian Nitrogen Hub (Grant NE/S009019/1).

Limitations

• Dataset scope is limited to a single experimental site in Queensberry, Sri Lanka, in 2022.
• Specific sample size, row count, and column details are unknown from the provided input.
