Applications are invited for a Postdoctoral Research Assistant in Atmospheric Physics. This post is fixed term for 3 years. Weather and climate predictions are of central importance to users spanning industries, charities, governments, and the public. For users to make cost- effective decisions, we must provide an estimate of uncertainty in the forecast. Arguably the dominant source of uncertainty is due to approximations made when building the model used to make predictions. However, representing model uncertainty is largely an afterthought: current approaches are crude and lack physical foundations. This project will bring model uncertainty to the fore. By seamlessly addressing the problem across weather and climate timescales, we will develop the foundational understanding needed to transform the reliability of Earth-system predictions. The successful candidate will undertake independent research, and participate in the academic life of the Atmospheric Processes group and the AOPP sub- department. Applicants should possess, or be close to obtaining, a doctorate in physics, climate science, or a related field. Previous experience in the field of predictability, uncertainty quantification, stochastic parametrisation, or weather and climate modelling will be an advantage. The post-holder will have the opportunity to teach. Please direct enquiries about the role to Hannah Christensen (hannah.christensen@physics.ox.ac.uk) Only applications received before midday 12th October 2023 can be considered. You will be required to upload a brief statement of research interests, CV and details of two referees as part of your online application.

_________________________________________________________________________ Job Description and Selection Criteria Job title Postdoctoral Research Assistant in Atmospheric Physics Division Mathematical Physical and Life Sciences Department Physics Location Oxford Grade and salary Grade 7: £36,024 - £44,263 per annum Hours Full time Contract type Fixed-term (36 months / 3 years) Reporting to Hannah Christensen Vacancy reference 167855 Additional information Closing date – midday 12th October 2023 Research topic Seamless Uncertainty Quantification for Earth System Prediction Principal Investigator / supervisor Hannah Christensen Project team Project web site https://www2.physics.ox.ac.uk/research/atmospheric-processes Funding partner The funds supporting this research project are provided by the Leverhulme Trust The role We are looking for an enthusiastic Postdoctoral Research Assistant to join the Atmospheric Processes group within the sub-Department of Atmospheric, Oceanic and Planetary Physics (AOPP). The post will be available for a period of 36 months. Weather or climate prediction involves combining information about the current state of the Earth-system with a computer model encoding the equations describing the system. Errors in the starting conditions, unknowable future greenhouse gas emissions (“forcings”), and approximations made when building the computer model all introduce uncertainty into the prediction. These uncertainties must all be accounted for to produce reliable forecasts. The approaches used to represent uncertainty in the starting conditions have firm mathematical foundations, while those used to represent forcing uncertainty are pragmatic but transparent. we therefore focus on the uncertainty in predictions due to limitations in the predictive model. This model uncertainty is a substantial source of uncertainty across weather and climate timescales so it must be accounted for in forecasts. However, there is no consensus on how to achieve this. At best, model uncertainty is represented as an afterthought in a heuristic or ad hoc manner; at worst it is ignored completely. The successful applicant will work with PI Christensen towards the long-standing aim of reliable probabilistic weather and climate forecasts. We will do this by bringing model uncertainty to the fore. The specifics of the project will be agreed on between the successful applicant and PI Christensen, but could include - The use of data assimilation increments to understand fast errors in atmospheric models - The interconnected nature of systematic and random errors in models, including between Earth-system components - The foundations and development of stochastic parametrisation schemes - Calibration methods for probabilistic predictions on weather and climate timescales, such as emergent constraints - The development of machine learning tools for uncertainty quantification While there has historically been a disconnect between the weather and climate communities, we will adopt a seamless, joined-up approach, using insights from the weather community to benefit the climate community, and vice versa. The conclusions we draw will therefore have relevance across the two communities. We will only achieve our aim of reliable probabilistic weather and climate forecasts by both communities using a consistent, physically motivated approach to account for model uncertainty. The post holder will work closely with Dr Christensen, and with national and international collaborative partners to meet the goals of the project. Responsibilities The successful candidate will undertake independent research, and participate in the academic life of the Atmospheric Processes group and the AOPP sub-department. Their duties will be to:  Manage own academic research, including the development of original research and analysis strategies.  Play a major role in the preparation of high-impact peer-reviewed journal articles.  Present the results at national and international meetings.  The post-holder will have the opportunity to teach. This may include lecturing, small group teaching, and tutoring of undergraduates and graduate students. 167855 Christensen_jd-and-person-spec-SUQCES.doc 2 Selection criteria Essential  Good first degree in physics, mathematics, or related sciences.  Doctorate (or close to obtaining) in physics, climate science, or related fields.  Strong computing skills, including the knowledge of UNIX/Linux, and Fortran, Python, or other high-level languages  Demonstrated drive and ability to perform novel research of international standing.  Excellent communication skills, including the ability to write for publication, present research results, and represent the research group at meetings.  Ability to manage own project-related research and associated activities.  Ability to work collaboratively Desirable  Excellent understanding of atmospheric physics.  Experience in weather and climate modelling.  Experience with stochastic parametrisation, uncertainty quantification, or Earth-system predictability Pre-employment screening  All offers of employment are made subject to standard pre-employment screening, as applicable to the post.  If you are offered the post, you will be asked to provide proof of your right-to-work, your identity, and we will contact the referees you have nominated.
