Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 4827-4850 (2024)

This study analyses three extreme ozone (O3) episodes that occurred in Barcelona (NE Spain) during the summers of 2015, 2018, and 2019. These episodes exceeded the EU's hourly information threshold (180 µg m−3) for the first time since at least th

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 4305-4329 (2024)

A tropospheric O3 pollution episode over the Atlantic coast of the Iberian Peninsula during 2–6 August 2018 has been analyzed. The episode was characterized by a permanent wind shear throughout the entire period, making the observed ozone surface d

Analysis of summer O3 in the Madrid air basin with the LOTOS-EUROS chemical transport model

Autor: M. Escudero, A. Segers, R. Kranenburg, X. Querol, A. Alastuey, R. Borge, D. de la Paz, G. Gangoiti, M. Schaap

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 14211-14232 (2019)

Tropospheric O3 remains a major air-quality issue in the Mediterranean region. The combination of large anthropogenic emissions of precursors, transboundary contributions, a warm and dry aestival climate, and topographical features results in severe

Ozone source apportionment during peak summer events over southwestern Europe

Autor: M. T. Pay, G. Gangoiti, M. Guevara, S. Napelenok, X. Querol, O. Jorba, C. Pérez García-Pando

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 5467-5494 (2019)

It is well established that in Europe, high O3 concentrations are most pronounced in southern/Mediterranean countries due to the more favourable climatological conditions for its formation. However, the contribution of the different sources of precur

Phenomenology of summer ozone episodes over the Madrid Metropolitan Area, central Spain

Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 6511-6533 (2018)

Various studies have reported that the photochemical nucleation of new ultrafine particles (UFPs) in urban environments within high insolation regions occurs simultaneously with high ground ozone (O3) levels. In this work, we evaluate the atmosphe

Phenomenology of high-ozone episodes in NE Spain

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Iss 4, Pp 2817-2838 (2017)

Ground-level and vertical measurements (performed using tethered and non-tethered balloons), coupled with modelling, of ozone (O3), other gaseous pollutants (NO, NO2, CO, SO2) and aerosols were carried out in the plains (Vic Plain) and valleys of the
