Atmospheric chemistry in cold environments Faraday Discussion

17 - 19 February 2025, London, United Kingdom


Phishing Warning
We are aware that some speakers and delegates have been approached by companies claiming to operate on behalf of the Royal Society of Chemistry to book their travel and accommodation for our conferences. Please note that whilst we do sometimes work with accommodation providers in order to facilitate hotel bookings, they would never approach you in the first instance. Details of accommodation providers that we are working with are in the ‘accommodation’ section of this webpage. If you are unsure about an e-mail / phone call you receive, please contact us and do not provide any credit card details or personal information.
Introduction

Welcome

Join us in London in February 2025 for the latest addition to our Faraday Discussion series, with their unique format allowing for in-depth discussions of research manuscripts. We invite you to submit an oral or poster abstract to share your contribution alongside leaders in the field. This meeting is aimed at scientists working in the disciplines of atmospheric science, physics, chemistry, sea-ice science, meteorology, and oceanography, to discuss their results from field campaigns, laboratory experiments, atmospheric modeling, and computational work.
 
We are looking forward to welcoming you, in person or online, in Central London at the Royal Society of Chemistry.

Format

Faraday Discussions remain amongst the only conferences to distribute the speakers’ research papers in advance, allowing the majority of each meeting to be devoted to discussions in which all delegates can participate. Following each meeting, a written record of the discussions is published alongside the papers in the Faraday Discussion journal. The discussions will be moderated by the session chair.

Themes

The discussions will centre around wintertime and cold region atmospheric chemistry and its impacts on health, geochemical cycles, and climate. Central to this discussion are aspects that make gas- and multiphase atmospheric science in cold environments unique, including but not limited to the presence of ice clouds, snow, and sea ice.

Multiphase chemistry in aerosol, ice/mixed-phase clouds, and snow

Multiphase processes have long been identified as key contributors to air quality and the chemical cycling between the atmosphere and hydrosphere. A key challenge lies in constraining the physical chemistry, such as rate coefficients and solubility data, to the conditions present in the often dry and cold wintertime atmosphere. This meeting addresses the formation and processing of airborne aerosol in wintertime atmospheres and at higher altitudes in the troposphere where cold temperatures prevail year-round, as well as the chemistry of deposited aerosol and brine patches in snow and sea ice. Furthermore, liquid aerosol will solidify as temperatures drop in these regions as part of daily or seasonal cycles. As such, interfacial chemistry at these solid aerosol particles and nucleation processes for complex mixtures is another topic of this conference.

Role of trace gases in particle and ice nucleation and growth

Cloud formation in cold regions of the atmosphere, such as the Southern and Arctic Oceans, wintertime cities, or the upper troposphere, is another key topic. Uncertainties in the concentrations and chemistry of precursor trace gases and vapors that contribute to particle growth, including biogenic components, pose key research questions. Further challenges lie in the interplay of gas-phase chemistry with particle nucleation and growth at cold temperatures. Of additional interest is the study of substances such as fluorinated persistent organics whose atmospheric abundance is driven by innovation in consumer products, changes in traffic routes, etc.

Exchange processes through/in snow and sea-ice

Sea ice and snow are key media at the ocean-atmosphere interface, where chemicals from the ocean accumulate, or are produced. On land, snow covers soil, a chemically and biologically active surface. We invite contributions on this topic, including but not limited to: trace gas fluxes, the description of the permeability of these matrixes for gases, the role of wind and wind-induced pressure fields, aerosol transport through snow, and changes of sea ice and snow with time and space. Further topics also include the impact of snow on the ground and sea ice, providing reactive surfaces for heterogeneous chemistry.

Emissions of trace gases and aerosol and atmospheric mixing/transport

Both biogenic and anthropogenic emissions differ significantly under varying atmospheric temperature ranges. For example, in the winter or in colder regions, homes need to be heated more extensively, which is typically done by the combustion of wood, oil, coal, or natural gas, and can be a large contributor to local emissions. We invite contributions on this topic, including those focusing on source apportionment, and the role of meteorology and transport on observed pollution levels. Furthermore, biogenic emissions by soil and plants show distinct changes with temperature that are still a challenge to account for. Additionally, considerable efforts so far have focused on wind-driven sea spray aerosol and trace gas emission in the Southern Ocean and as such, we invite contributions on the composition of trace gas emissions from sea ice and from the open ocean.

Grants for Carers

Grants for carers have been introduced following the Royal Society of Chemistry Breaking the barriers report where 78% of chemists working in UK academia felt that managing parenting and/or caring responsibilities has an impact on women’s retention and progression. This fund is not limited to women scientists and welcomes applications from anyone with caring responsibilities. These grants have been supported by The Royal Society of Chemistry’s Chemists’ Community Fund.

You can apply for up to a maximum of £1200/year to assist with additional financial costs that you incur for care usually provided by you whilst you attend a chemistry related meeting, conference or workshop or a professional development event.

Caring responsibilities are wide and varied, and so each application will be individually assessed, examples of applications that we will consider include:
  • paying for extra home help or nursing care for a dependent whilst you will not be present
  • additional medical/respite care for a dependent whilst you will not be present
  • travel expenses for a relative to travel with you to care for dependents whilst you attend a meeting or event
  • paying for extended hours with a care worker/childminder/play scheme to cover time when you will arrive home later than normal.
You are eligible to apply if: 
  • you are a chemist
  • you will incur additional caring expenses whilst attending a chemistry-related meeting, conference, event or workshop or a professional development event
  • you will use these funds to cover the cost of care that you usually provide 
  • you are based in the UK or Ireland or if not, you will normally have held three years RSC membership (past or current).
Sponsorship and Supporting organisations
A selection of sponsorship opportunities is available for companies who would like to promote their activities at the 2025 Faraday Discussion series.
