PhD: Local and remote sources of Arctic air pollution
Laboratoire Atmosphères, Milieux, Observations Spatiales (LATMOS), Paris, France
The Arctic is undergoing unprecedented changes as a result of global warming due to long-lived greenhouse gases, notably carbon dioxide, and short-lived climate forcers including pollutants such as black carbon and ozone. Whilst pollutant climate effects in the Arctic are primarily due to long-range transport of aerosols, ozone and their precursors from mid-latitudes, it is now apparent that there are already local anthropogenic emissions of air pollutants (e.g. resource extraction, domestic combustion) that can also impact climate, either directly or indirectly by affecting cloud properties or as a result of black carbon deposition on snow reducing surface albedo. Air pollutants can also impact ecosystems or local/regional air quality and human health. Local Arctic emissions are likely to increase in the future as a result of global warming providing opportunities for increased industrial activity. However, large uncertainties exist about the processes influencing the formation and impacts of local aerosol pollution. In particular, in winter/early spring, severe pollution episodes occur due to enhanced emissions in very cold temperatures and stable meteorological conditions, superimposed on pollution transported from mid-latitude (Arctic Haze phenomena).
The proposed PhD research, selected as part of the French Make Our Planet Great Again Programme (MOPGA) (see full PhD topic description at https://doctorat.campusfrance.org/CF201812512 and below for conditions) will use a combination of analysis of existing and new data, for example collected during a planned international ALPACA field campaign in Fairbanks, Alaska, together with 1D box and regional (WRF-Chem) chemical-aerosol modelling to improve understanding about wintertime pollution formation, the role of interactions with boundary layer dynamics and impacts of local emissions on climate and atmospheric composition relative to impacts of remote sources. WRF-Chem will also be used to assess future impacts of local pollution sources in Alaska and the wider Arctic relative to pollution transported from mid-latitudes. The research will be carried out as part of the ALPACA activity (https://alpaca.community.uaf.edu/) under the international PACES (Pollution in the Arctic: Climate, Environment and Societies) initiative (see http://www.igacproject.org/PACES).
The successful candidate will be part of the TROPO group in LATMOS that has been working for several years on long-range transport of pollutants to the Arctic and local sources of Arctic pollution using analysis of observations and regional chemical/aerosol modelling (e.g. see Law et al., Ambio, 2017). The PhD student will be based at LATMOS on Jussieu campus of the Sorbonne University in central Paris, see http://www3.latmos.ipsl.fr/index.php/fr/ and http://sorbonne-universite.fr/en. LATMOS is also part of the Institute Pierre Simon Laplace (IPSL) (http://www.ipsl.fr/), carrying out research into a wide range of topics related to atmospheric and climate science.
