    • An integrated model system tool to evaluate the impact of urban mobility policies on air pollution: Barcelona case study 

      Rodriguez-Rey, Daniel; Guevara, Marc; Casanovas Garcia, Josep (Barcelona Supercomputing Center, 2020-05)
      Conference report
      Open Access
      Air pollution remains as a key unresolved problem in many urban areas. Cities with such problem are gradually implementing Traffic Management Strategies (TMS) to reduce the total kilometers travelled by vehicles and ...

    • CALIOPE-Urban v1.0: coupling R-LINE with a mesoscale air quality modelling system for urban air quality forecasts over Barcelona city (Spain) 

      Benavides, Jaime; Snyder, Michelle; Guevara, Marc; Soret, Albert; Pérez García-Pando, Carlos; Amato, Fulvio; Querol, Xavier; Jorba Casellas, Oriol (Copernicus Publications, 2019)
      Article
      Open Access
      he NO2 annual air quality limit value is systematically exceeded in many European cities. In this context, understanding human exposure, improving policy and planning, and providing forecasts requires the development of ...

    • Evaluation of traffic emission models coupled with a microscopic traffic simulator and on-road measure 

      Rey, Daniel R.; Soret, Albert; Guevara, Marc; Linares, Mari Paz (Barcelona Supercomputing Center, 2018-04-24)
      Conference report
      Open Access
      This study aims to compare and contrast the emission results of two instantaneous traffic emission models coupled with a microscopic traffic simulator and COPERT. These will be evaluated with the observed results of on-road ...

    • HERMESv3, a stand-alone multi-scale atmospheric emission modelling framework – Part 1: global and regional module 

      Guevara, Marc; Tena, Carles; Porquet, Manuel; Jorba, Oriol; Pérez García-Pando, Carlos (European Geosciences Union (EGU), 2019-05-14)
      Article
      Open Access
      Abstract Back to top We present the High-Elective Resolution Modelling Emission System version 3 (HERMESv3), an open source, parallel and stand-alone multi-scale atmospheric emission modelling framework that computes ...

    • HERMESv3, a stand-alone multi-scale atmospheric emission modelling framework – part 2: the bottom–up module 

      Guevara, Marc; Tena, Carles; Porquet, Manuel; Jorba Casellas, Oriol; Pérez García-Pando, Carlos (Copernicus Publications, 2020-03)
      Article
      Open Access
      We describe the bottom–up module of the High-Elective Resolution Modelling Emission System version 3 (HERMESv3), a Python-based and multi-scale modelling tool intended for the processing and computation of atmospheric ...

    • Local traffic contribution to black carbon horizontal and vertical profiles in compact urban areas 

      Benavides, Jaime; Guevara, Marc; Jorba Casellas, Oriol (Barcelona Supercomputing Center, 2019-05-07)
      Conference report
      Open Access
      Urban air pollution is characterized by strong spatial gradients produced by the presence of heavily trafficked streets. Given the negative health effects of air pollution, decision makers are implementing policies to ...

    • Meteorology-normalized impact of the COVID-19 lockdown upon NO2 pollution in Spain 

      Petetin, Hervé; Bowdalo, Dene; Soret, Albert; Guevara, Marc; Jorba Casellas, Oriol; Serradell Maronda, Kim; Pérez García-Pando, Carlos (Copernicus Publications, 2020)
      Article
      Open Access
      The spread of the new coronavirus SARS-CoV-2 that causes COVID-19 forced the Spanish Government to implement extensive lockdown measures to reduce the number of hospital admissions, starting on 14 March 2020. Over the ...

    • On the impact of excess diesel NOX emissions upon NO2 pollution in a compact city 

      Benavides, Jaime; Guevara, Marc; Snyde, Michelle G; Rodríguez Rey, Daniel; Soret, Albert; Pérez García-Pando, Carlos; Jorba Casellas, Oriol (IOP Publishing Ltd, 2021)
      Article
      Open Access
      NOX emissions from diesel light-duty-vehicles (LDV) largely exceed the Euro emission standards in real-world driving conditions. Recent studies have quantified their impact upon air quality and human health primarily based ...
