Overview

The RIVM Aerius calculation tool calculates the impact of various emission sources on nitrogen deposition on Natura 2000 areas in the Netherlands.
The general concept is:

  1. Various sources, such as traffic and industry, emit NOx and NH3 into the air. The NOx and NH3 in the air eventually ends up on the ground, which is called nitrogen deposition. Nitrogen deposition is especially bad for the plants in nature reserves (Natura 2000 areas). For more information, see this https://www.rivm.nl/stikstof (in Dutch).
  2. These sources of emissions are categorized by the Aerius Calculator into different (specific) sectors.
  3. Aerius calculate for these different sectors the corresponding emissions and the amount of nitrogen deposition on Natura 2000 areas.

Supported Sectors

The Aerius Calculator tool can calculate emissions for various sectors. Currently supported sectors in the Tygron Platform are:

  • Traffic (Wegverkeer):
    • Sector 3113: local roads (Binnen bebouwde kom)
    • Sector 3112: rural roads (Buitenwegen)
    • Sector 3111: highways (Snelwegen)
  • Mobile machines (Mobiele werktuigen):
    • Sector 3220: Construction and industrial machines (Bouw en industrie)
  • Plan (Plan):
    • Sector 9000: used construction materials and constructed type of buildings (all categories).
  • Work and living (Wonen en werken):
    • 8640: Work (Kantoren en winkels)
    • 8200: Living (Woningen)
    • 8210: Recreation (Recreatie)

Input

The input needed to make a calculation and visiualize the results in the Aerius Overlay, depends on the use case and the available data. Below an overview of the different datasets that can serve as input:

Output

  • Emissions per construction. The emissions are added as attributes to the construction with the NOX and NH3 attributes.
  • Two result types (grid overlays) showing either the NOX or NH3 deposition in Natura 2000 areas as hexagon areas.
  • An array of NOx or NH3 values in mol/hectare/year per hexagon area stored in the Aerius Overlay under the NOX and NH3 keys.
