Postdoctoral Fellow in Physics (Lund University)

Lund University was founded in 1666 and is repeatedly ranked among the world’s top universities. The University has around 47 000 students and more than 8 800 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition. Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset. Description of the workplace The post-doctoral position is placed at the division of Combustion Physics. The aerosol research group at combustion physics conducts research on atmospheric aerosol particles and their impact on climate and air quality. This research involves aerosol in-situ measurements, satellite measurements, process modelling and global modelling. The research group is part of the strategic research area MERGE (https://www.merge.lu.se) that work with climate modelling. Aerosol research has been conducted at Lund University since the 1970-ies and Aerosols is now a profile area at the Faculty of Engineering (https://www.lth.se/english/research/profile-areas/aerosols/). Combustion physics has approximately 70 employees and is located in the Enoch Thulin-laboratory at the Physics Department. The division actively works to create a friendly working environment and has a well-being group that arranges board game nights, excursions, and other activities. The postdoctoral position is focused the climatic impact of volcanic eruptions with an aim of reducing the uncertainties in projections of the future climate. The project will utilise SO2 and aerosol data retrieved by satellite instruments and a global climate model. Subject description The subject of the position is volcanic effluents and how they impact the stratosphere and climate. Work duties Explosive volcanic eruptions can inject millions of tons of particle forming sulphur dioxide (SO2) into the stratosphere elevating the stratospheric aerosol load. Stratospheric particles have lifetimes on the order of months or years inducing long lasting climate cooling. The resulting climate impact highly depends on the injection altitude. Most SO2 instruments have very limited, if any, vertical resolution adding uncertainty in the current model simulations. This project focuses on combining satellite data and global climate modelling to estimate the climate cooling from volcanic eruptions. We have developed a method to produce high vertical resolution SO2 data (see Sandvik et al. 2021: doi.org/10.5194/amt-14-7153-2021). You will apply our SO2 method to volcanic eruptions that reached the stratosphere during the past 20 years. This data will be implemented in the global climate model WACCM. You will study the aerosol particle’s formation, distribution, and their climate cooling effect predicted by the model, and compare it with previous simulation results. The model results will also be compared with aerosol observations from satellites to validate the simulations (see Axebink et al. 2024: doi.org/10.5194/egusphere-2024-1448). The overarching goal is to gain a better understanding on volcanism’s impact on the climate. The main duties involved in a post-doctoral position is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The position includes the opportunity for three weeks of training in higher education teaching and learning. The purpose of the position is to develop the independence as a researcher and to create the opportunity of further development. Qualification requirements Appointment to a post-doctoral position requires that the applicant has a PhD, or an international degree deemed equivalent to a PhD, within the subject of the position. The certificate proving the qualification requirement is met, must be received before the employment decision is made. Priority will be given to candidates who have graduated no more than three years ago before the last day for application. Under special circumstances, the doctoral degree can have been completed earlier. Additional requirements: Very good oral and written proficiency in English. Good knowledge in programming. Comprehensive knowledge about atmospheric physics and/or chemistry. Assessment criteria and other qualifications This is a career development position primarily focused on research. The position is intended as an initial step in a career, and the assessment of the applicants will primarily be based on their research qualifications and potential as researchers. Particular emphasis will be placed on research skills within the subject. For appointments to a post-doctoral position, the following shall form the assessment criteria: A good ability to develop and conduct high quality research. Teaching skills. Other qualifications: Prior experience in working with satellite data of gases or aerosols. Prior experience in working with climate modelling or data therefrom. Knowledge in Matlab or Python programming (or similar). Prior work with emissions from volcanic eruptions. You are independent, have good collaboration skills, likes to take initiatives and are well structured. Consideration will also be given to how the applicant’s experience and skills complement and strengthen ongoing research within the department, and how they stand to contribute to its future development.
