Estimating lockdown-induced European NO2 changes using satellite and surface observations and air quality models
Barré, Jérôme; Petetin, Hervé; Guevara Vilardell, Marc; Pérez García-Pando, Carlos; Bowdalo, Dene; Jorba Casellas, Oriol (Copernicus Publications, 2021)
Article
Open AccessThis study provides a comprehensive assessment of NO2 changes across the main European urban areas induced by COVID-19 lockdowns using satellite retrievals from the Tropospheric Monitoring Instrument (TROPOMI) onboard the ... -
Intercomparison and sensitivity analysis of gas-phase dry deposition schemes
López Coronado, Franco Rodrigo; Gonçalves Ageitos, María; Bowdalo, Dene; Jorba Casellas, Oriol (Springer, 2023-01-02)
Part of book or chapter of book
Restricted access - publisher's policyThe dry deposition of gaseous species, such as ozone, sulphur dioxide and nitrogen oxides, is a major pathway in its removal from the atmosphere. Chemical Transport Models (CTM) commonly use a resistance approach to determine ... -
Meteorology-normalized impact of the COVID-19 lockdown upon NO2 pollution in Spain
Petetin, Hervé; Bowdalo, Dene; Soret, Albert; Guevara Vilardell, Marc; Jorba Casellas, Oriol; Serradell Maronda, Kim; Pérez García-Pando, Carlos (Copernicus Publications, 2020)
Article
Open AccessThe 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 ... -
Model output statistics (MOS) applied to Copernicus Atmospheric Monitoring Service (CAMS) O3 forecasts: trade-offs between continuous and categorical skill scores
Petetin, Hervé; Bowdalo, Dene; Bretonnière, Pierre-Antoine; Guevara Vilardell, Marc; Jorba, Oriol; Mateu Armengol, Jan; Samso Cabre, Margarida; Serradell, Kim; Soret, Albert; Pérez García-Pando, Carlos (Copernicus Publications, 2022)
Article
Open AccessAir quality (AQ) forecasting systems are usually built upon physics-based numerical models that are affected by a number of uncertainty sources. In order to reduce forecast errors, first and foremost the bias, they are ... -
Time-resolved emission reductions for atmospheric chemistry modelling in Europe during the COVID-19 lockdowns
Guevara Vilardell, Marc; Jorba Casellas, Oriol; Soret, Albert; Petetin, Hervé; Bowdalo, Dene; Serradell Maronda, Kim; Tena, Carles; Gon, Hugo Denier van der; Kuenen, Jeroen; Peuch, Vincent-Henri; Pérez García-Pando, Carlos (Copernicus Publications, 2021)
Article
Open AccessWe quantify the reductions in primary emissions due to the COVID-19 lockdowns in Europe. Our estimates are provided in the form of a dataset of reduction factors varying per country and day that will allow the modelling ...
