PAREST – Particle Reduction Strategies

Development of an integrated approach for the Assessment of abatement  strategies of Particulate Matter concentrations in Germany


funded by the Environmental Protection Agency Germany (UBA), 2007-2010


Objective of the project:


According to model based assessment of future air quality, exceedances of the PM10 limit values in Germany will continue despite the implementation of the current national and international emission reduction legislation. Thus, further measures are necessary to reduce national emissions in order to mitigate pollutant impacts and achieve environmental improvement targets. In this context, the objective of the PAREST-project is twofold:     Development of highly resolved, state-of-the-art emission inventories for Europe and in particular for Germany and    identification of appropriate further abatement measures and strategies   Assessment of current and future air quality by use of several chemistry-transport models (CTMs) and quantification of
benefit of further abatement measures on the international, national and local scale  

PAREST is an interdisciplinary collaborative research project carried out by several national and international institutions.

  The TRUMF group has the leading role in the air quality modelling part of the project. Furthermore, the CTM REM-CALGRID (RCG), developed at the Institute for Meteorology, is the major assessment tool for the scenario analysis and optimisation.    

The scientific research within PAREST focuses on:

       Evaluation and inter-comparison of the involved CTMs       RCG, FU Berlin       LOTOS-EUROS, TNO, The Netherlands       COSMO-MUSCAT, Leibniz Institute for Tropospheric Research      Improvement of the physical and chemical aerosol treatment


   Continuing development of data assimilation techniques       to combine air quality observations with model results      Continuing development of meteorological drivers for RCG
