Mitigation of PM2.5 and ozone pollution in Delhi: a sensitivity study during the pre-monsoon period

Autor: Y. Chen, O. Wild, E. Ryan, S. K. Sahu, D. Lowe, S. Archer-Nicholls, Y. Wang, G. McFiggans, T. Ansari, V. Singh, R. S. Sokhi, A. Archibald, G. Beig

Publikováno v: Atmospheric Chemistry and Physics, Vol 20, Pp 499-514 (2020)

Fine particulate matter (PM2.5) and surface ozone (O3) are major air pollutants in megacities such as Delhi, but the design of suitable mitigation strategies is challenging. Some strategies for reducing PM2.5 may have the notable side effect of incre

Two-scale multi-model ensemble: is a hybrid ensemble of opportunity telling us more?

Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 8727-8744 (2018)

In this study we introduce a hybrid ensemble consisting of air quality models operating at both the global and regional scale. The work is motivated by the fact that these different types of models treat specific portions of the atmospheric spectr

Evaluation and error apportionment of an ensemble of atmospheric chemistry transport modeling systems: multivariable temporal and spatial breakdown

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Iss 4, Pp 3001-3054 (2017)

Through the comparison of several regional-scale chemistry transport modeling systems that simulate meteorology and air quality over the European and North American continents, this study aims at (i) apportioning error to the responsible processes us

Insights into the deterministic skill of air quality ensembles from the analysis of AQMEII data

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 15629-15652 (2016)

Simulations from chemical weather models are subject to uncertainties in the input data (e.g. emission inventory, initial and boundary conditions) as well as those intrinsic to the model (e.g. physical parameterization, chemical mechanism). Multi-

Publikováno v: Geoscientific Model Development, Vol 9, Iss 2, Pp 451-478 (2016)

We present an overview of the modelling of particle number concentrations (PNCs) in five major European cities, namely Helsinki, Oslo, London, Rotterdam, and Athens, in 2008. Novel emission inventories of particle numbers have been compiled both on u

Online coupled regional meteorology chemistry models in Europe: current status and prospects

Publikováno v: Atmospheric Chemistry and Physics, Vol 14, Iss 1, Pp 317-398 (2014)

Online coupled mesoscale meteorology atmospheric chemistry models have undergone a rapid evolution in recent years. Although mainly developed by the air quality modelling community, these models are also of interest for numerical weather prediction a

Integrated systems for forecasting urban meteorology, air pollution and population exposure

Autor: A. Baklanov, O. Hänninen, L. H. Slørdal, J. Kukkonen, N. Bjergene, B. Fay, S. Finardi, S. C. Hoe, M. Jantunen, A. Karppinen, A. Rasmussen, A. Skouloudis, R. S. Sokhi, J. H. Sørensen, V. Ødegaard

Publikováno v: Atmospheric Chemistry and Physics, Vol 7, Iss 3, Pp 855-874 (2007)

Urban air pollution is associated with significant adverse health effects. Model-based abatement strategies are required and developed for the growing urban populations. In the initial development stage, these are focussed on exceedances of air quali
