UK Critical Load Exceedance Maps For Acidity And Nitrogen 2014-2016

United Kingdom 1x1 km resolution maps quantify the exceedance of critical loads for acidity across eight habitats and for nutrient nitrogen across thirteen habitats. The data calculates Average Accumulated Exceedance (AAE) using 5x5 km deposition estimates from 2014 to 2016 to assess environmental risk from atmospheric pollutants.

Use Cases

• Spatially analyze the relationship between 1x1 km AAE values and habitat types to identify the most impacted ecosystems.
• Model the potential reduction in exceedance areas for the eight acidity-sensitive habitats under different emission policy scenarios.
• Compare the geographic distribution and severity of exceedance between the thirteen nutrient nitrogen-sensitive habitats.
• Integrate AAE data with 5x5 km Concentration Based Estimated Deposition (CBED) inputs to validate or refine deposition models.

Strengths

• Provides 1x1 km spatial resolution for detailed geographic analysis.
• Covers two distinct pollutant types (acidity and nutrient nitrogen) across a total of 21 specific habitat categories.
• Based on a defined three-year time period (2014-2016) of UK deposition data.

Limitations

• Data is temporally static, representing a specific historical period (2014-2016) and may not reflect current conditions.
• The underlying deposition inputs are at a coarser 5x5 km resolution, which the 1x1 km AAE maps interpolate or derive from.
• Analysis is limited to the United Kingdom and may not be generalizable to other regions with different ecosystems or pollution profiles.
