Experiments with RAINS-NL

This paper by Jan Aben, presented at the RAINS-NL workshop in Rome (May 2006), explores the features and objectives of the RAINS-NL model, emphasizing its increased spatial resolution for assessing air quality in the Netherlands. Key objectives include analyzing the effects of Euro V and VI emission standards on PM2.5 and NO2 levels in urban areas. Findings indicate that while these standards are crucial for reducing emissions, they may not suffice to meet air quality targets in high pollution hotspots. The study underscores the need for detailed analyses to inform national strategies for improved air quality.

  1. Jan Aben Experiments with RAINS-NL

  2. Contents • Features and objectives of RAINS-NL • Illustration of a feature • Exploration of Euro V and Euro VI effects on PM2.5 emissions and concentrations • Conclusions Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  3. Features • Increased spatial resolution (NL domain only) • EMEP based TM’s (50x50 km)  OPS based TMs (5x5 km) • high resolution ecosystem and population data • Sector specific transfer matrices allowing better spatial allocation of control measures • NO2 concentration Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  4. Objectives of RAINS-NL • Providing a general framework for IA analysis • Detailing RAINS outcomes for the Netherlands • Studying the effects of alternative national strategies, including the consequences for other countries Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  5. Increased resolution in RAINS-NL RAINS underestimates N-problem in hot spots Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  6. Effects of EURO V and VI on NO2 and PM2.5 • NO2 and PM are bottlenecks in Dutch cities • Traffic is an important source of NOx and PM emissions • Investigation into the effects of proposed EURO standards on PM2.5 concentrations Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  7. Two alternative strategies • MOBv1: Starts from Commission proposal Euro V for cars and vans (starting ± 2008) and European stimulation of cleaner trucks (Euro IV and V) • MOBv2: Starts from Commission proposal EURO V for cars and vans and EURO VI (starting ± 2012) for cars and trucks (Ricardo) Alternative strategies applied to NL, BE, GE, FR, UK Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  8. Development of shares of Euro standards Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  9. Reduction of NOx emission by road traffic in 2020 Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  10. Reduction of PM2.5 emission by road traffic in 2020 Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  11. Effect on PM2.5 concentration in 2020 - NL Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  12. Spatial allocation of effect on PM2.5 concentration RAINS/EMEP underestimates effect of measures for hot spots Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  13. PM2.5 concentrations along city streets in 2020 Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006

  14. Conclusions • Euro V and VI are essential measures to reduce PM2.5 (and NO2) in Dutch urban locations (but possibly not sufficient to meet indicative targets everywhere) • RAINS/EMEP underestimates problems in hot spots • RAINS/EMEP underestimates effects of measures for hot spots Jan Aben, Experiments with RAINS-NL, Rome, 17-19 May 2006
