Atmosphere, Ice and Climate team
Our ambition
The polar atmosphere-ocean-sea-ice system is highly-coupled and interconnected. Our overriding vision is to understand processes that drive this system and assess responses to our changing world. More robust predictions of the polar system, and how it links globally, are critical for guiding future climate policy decisions. While we focus primarily on the polar regions, we also address associated global questions that are best probed at lower latitudes.
Our research groups investigate (i) climate variability, change and predictability, with primary emphasis on high latitudes and altitudes; (ii) physical processes that control the polar atmosphere and sea ice, including cloud processes, and (iii) chemical processes that control composition of the polar atmosphere, their climate interactions, and how they link to the interpretation of ice core records. Additionally, the team is responsible for maintaining long-term observations of weather, climate and atmospheric composition at our research stations and from a number of remote sites.
Team priorities
Science
- Determine patterns of change and variability in the high-latitude atmosphere. Optimise the use and analysis of sustained, long-term observations of meteorology and composition.
- Atmosphere-ocean-sea ice interactions. Explore the ways in which the polar atmosphere interacts with the polar oceans, cryosphere, upper atmosphere and the global climate system.
- Climate and atmospheric composition. Carry out targeted studies (using both observations and models) of key processes that control polar climate and atmospheric composition, including atmosphere-ocean-sea ice interaction, sea-ice dynamics, clouds, aerosols, atmospheric waves and turbulence.
- Determine the causes of climate change in the polar regions. To what degree can observed change be attributed to human forcings (greenhouse gases, stratospheric ozone depletion), natural forcings (e.g. volcanic aerosols, solar variability) and internal variability (“chaos”)?
- Reduce uncertainty in predictions of polar and global climate and atmospheric composition through improved representation of polar processes in atmospheric, climate and earth system models.
- Apply our polar expertise and assets to address crucial global questions that are best probed at lower latitudes.
Technology, innovation and training
- Use state-of-the-art scientific instrumentation, as well as BAS’s unique polar platforms (airborne and ground-based), to achieve science priorities
- Exploit novel autonomous platforms and instrumentation to open up new possibilities for observations.
- Develop and apply cutting-edge numerical models and data analysis techniques to solve defined science questions.
- Train the next generation of polar atmospheric scientists to tackle key questions in the future.
- Maintain a suite of meteorological and atmospheric chemistry equipment to deliver long-term observations for climate/composition research. Train personnel on the operation and maintenance of this equipment to ensure the best data quality.
Influencing and leading international programmes
- Collaborate with leading UK and international research teams to tackle high impact science questions and drive the research agenda
- Take a leading role in the planning and implementation of polar science programmes through organisations such as the Scientific Committee for Antarctic Research, the World Climate Research Programme and the International Association of Meteorology and Atmospheric Sciences
- Contribute sustained observations to World Meteorological Organisation (WMO) programmes, such as the Global Atmosphere Watch (GAW) and the Global Cryosphere Watch (GCW). Develop sustained observations at BAS stations to meet the requirements of these programmes
Stakeholder engagement
- Produce briefings on policy-relevant science for UK government departments.
- Work with the UK Met Office to determine priorities for meteorological observations in British Antarctic Territory
- Collaborate with instrument manufacturers to develop the systems that we need to deliver our science
Public engagement
- Disseminate our findings, published in the highest-impact journals, through presentations in leading national and international forums
- Participate in BAS media and public engagement programmes and support our early career scientists in their public engagement activities

A recent pause in Antarctic Peninsula warming
20 July, 2016
The rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. Stabilisation of the ozone hole along with natural climate variability were significant in bringing about the change. Together these influences have now caused the northern part of the peninsula to enter a temporary cooling phase. Temperatures remain higher than measured during the middle of the 20th Century and glacial retreat is still taking place. However, scientists predict that if greenhouse gas concentrations continue to rise at the current rate, temperatures will increase across the Antarctic Peninsula by several degrees Centigrade by the end of this century.

Three decades of remote sensing subarctic vegetation in northern Russia: A case study in science diplomacy
19 October, 2022 by Gareth Marshall
The vegetation at and beyond the northern edge of the world's boreal forest plays an important though imperfectly understood role in the climate system. This is particularly true within Russia,…Surface snow bromide and nitrate at Eureka, Canada in early spring and implications for polar boundary layer chemistry [preprint]
18 October, 2022 by Xin Yang
This study explores the role of snowpack in polar boundary layer chemistry, especially as a di-rect source of reactive bromine (BrOX=BrO+Br) and nitrogen (NOX=NO+NO2) in the Arctic springtime. Surface snow…Characteristics of surface “melt potential” over Antarctic ice shelves based on regional atmospheric model simulations of summer air temperature extremes from 1979/80 to 2018/19
14 October, 2022 by Andrew Orr, Ella Gilbert, Steve Colwell, Tony Phillips
We calculate a regional surface “melt potential” index (MPI) over Antarctic ice shelves that describes the frequency (MPI-freq, %) and intensity (MPI-int, K) of daily maximum summer temperatures exceeding a…Variability in Antarctic surface climatology across regional climate models and reanalysis datasets
23 September, 2022 by Andrew Orr
