    • Testing simple models for street wind conditions in Barcelona 

      Benavides, Jaime; Jorba Casellas, Oriol; Soret, Albert; Guevara Vilardell, Marc (Barcelona Supercomputing Center, 2017-05-04)
      Text en actes de congrés
      Accés obert
      Street wind speed and direction drive models to estimate air quality levels at street scale. In this study, simple models are combined with a mesoscale meteorological model to provide wind conditions at street level. Then, ...

    • The impact of different nitrous acid sources in the air quality levels of the Iberian Peninsula 

      Gonçalves Ageitos, María; Dabdub, Donald; Chang, W.L.; Saiz, F.; Jorba Casellas, Oriol; Baldasano Recio, José María (2010-11-30)
      Article
      Accés obert
      Hydroxyl radical (OH) is a primary oxidant in the atmosphere and affects both gasphase pollutants and particulate matter levels. Nitrous acid (HONO) acts as an important source of OH in the urban atmosphere. Therefore ...

    • The MONARCH high-resolution reanalysis of desert dust aerosol over Northern Africa, the Middle East and Europe (2007–2016) 

      di Tomaso, Enza; Escribano Alisio, Jeronimo; Basart Alpuente, Sara; Macchia, Francesca; Benincasa, Francesco; Bretonnière, Pierre-Antoine; Buñuel, Arnau; Castrillo Melguizo, Miguel; Gonçalves Ageitos, María; Jorba Casellas, Oriol; Klose, Martina; Montané Pinto, Gilbert; Obiso, Vincenzo; Olid García, Miriam; Pérez García-Pando, Carlos (Copernicus Office, 2022-06-21)
      Article
      Accés obert
      One of the challenges in studying desert dust aerosol along with its numerous interactions and impacts is the paucity of direct in situ measurements, particularly in the areas most affected by dust storms. Satellites ...
