The British Antarctic Survey in Cambridge (BAS) is looking for a Fortran Code Developer to join the British Antarctic Survey. The role will involve implementing physical equations within the atmospheric component of the UK Earth System Modelling Project (UKESM Model).

The successful applicant will work closely with the Met Office and University of Bristol.


You will be part of the BAS climate modelling group of Louise Sime, and may also join the MetOffice UKESM team. Louise’s group has worked to develop a better understanding changes in the ice sheets, sea ice, and climate in polar regions. Much of the groups effort goes into understanding ice core observations of stable water isotopes by using climate models. Water isotopes measured in ice are the key long-term record of past changes in the polar environmental and global climate. Water isotope enabled simulations, generated from your new climate model coding work, will enable us to understand how changes in ice sheets, sea ice, and climate imprint themselves in polar ice cores.

You will work closely with the University of Bristol, and will have substantial support from the MetOffice via online working environments and video links. Travel and subsistence is supported if and when necessary. The Met Office wrote the UKESM model. The University of Bristol are developing water isotope code for the ocean and land surface components of the UKESM.

Once your UKESM code development work is complete, you will be uniquely placed to deliver state-of-the-art UKESM water cycle science to the UK and international community. Throughout the project you will participate in important national and international (EU-TiPES; UKESM; SCAR) initiatives. You will be supported to develop your own independent research directions in the latter years of the post. We anticipate a strong likelihood that your post can be renewed – and will last beyond the guaranteed 4 years.

You will be supported in your career development by the British Antarctic Survey, and will join a vibrant and active community of code developers.

You will have experience of developing software and a degree in numeric discipline.


• PhD in atmospheric sciences or other numerate field (or equivalent research experience).

• A background in climate, meteorology, or oceanography would be useful.


• Lead the development of water isotope code for the atmospheric component of the UK MetOffice UKESM model.
• Ensure that all components of the UKESM with water isotope code are correctly integrated.
• Provide weekly updates/meetings with BAS supervisor and keep in bi-weekly contact with the Met Office and Bristol collaborators.
• Manage computing resources for your work.
• Run UKESM simulations, as may be required, for the EU-TiPES project.
• Contribute to TiPES papers.
• Attend project meetings.
• Other coding/simulation run duties, as required.
• From year three onward, develop own independent research directions.
