Assessment of the impact of the Covid-19 lockdown on air pollution over Spain using machine learning
(Barcelona Supercomputing Center, 2020-05)
Conference report
Open AccessThe rapid spread of the Covid-19 pandemic over Spain recently forced the Spanish authorities to implement drastic measures of social distancing through a strict lockdown of the population starting on March 14th. As ... -
Compliance with 2021 WHO air quality guidelines across Europe will require radical measures
(IOP Publishing, 2022)
Article
Open Access -
Estimating lockdown-induced European NO2 changes using satellite and surface observations and air quality models
(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
(Springer, 2023-01-02)
Part of book or chapter of book
Open AccessThe 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 ... -
Long-term evaluation of surface air pollution in CAMSRA and MERRA-2 global reanalyses over Europe (2003–2020)
(Copernicus Publications, 2023)
Article
Open AccessOver the last century, our societies have experienced a sharp increase in urban population and fossil-fuelled transportation, turning air pollution into a critical issue. It is therefore key to accurately characterize the ... -
Meteorology-normalized impact of the COVID-19 lockdown upon NO2 pollution in Spain
(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
(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 ... -
Potential of TROPOMI for understanding spatio-temporal variations in surface NO2 and their dependencies upon land use over the Iberian Peninsula
(European Geosciences Union (EGU), 2023-04-03)
Article
Open AccessIn orbit since late 2017, the Tropospheric Monitoring Instrument (TROPOMI) is offering new outstanding opportunities for better understanding the emission and fate of nitrogen dioxide (NO2) pollution in the troposphere. ... -
Time-resolved emission reductions for atmospheric chemistry modelling in Europe during the COVID-19 lockdowns
(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 ...
