SHERPA – City

Screening for High Emission Reduction Potentials on Air quality – City

Following the experience of SHERPA – Screening for High Emission Reduction Potentials on Air quality, and again in the framework of the EU Thematic Strategy for Air Quality (COM 2005 446) and the EU Directive 2008/50/EC, the Joint Research Centre decided to develop a new screening tool expressly dedicated to cities, SHERPA-City. It is a quick and easy integrated city-scale modeling assessment (IAM) that enables rapid exploration of potential air quality improvements resulting from the implementation of traffic measures (e.g. traffic calming, heavy-duty vehicle limitation, diesel or Euro 1/2/3…) in EU cities at the local scale (20×20 m2), which are the key ones in critical air pollution episodes. SHERPA-City is a web application that uses a “kernel” approach: local traffic emissions through specific hourly source-receptor functions (Gaussian kernels), so that the calculation is fast and reliable even at high resolution.

 

THE ROLE OF TERRARIA

TerrAria fully developed the web-tool in terms of both the interface and the preprocessors for input/output management.
