Researcher in Modeling of Aerosols, Cold Clouds and Climate
Lund University, Natural Science Faculty
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.
There is scientific uncertainty about how much climate change will occur in future for any given scenario of emissions of greenhouse gases. The reason for most of this uncertainty is that clouds are especially challenging to represent in numerical models of the atmosphere. Clouds affect the Earth’s radiation budget. Changes in their properties, either due to global warming or aerosol pollution, can strongly modify any ongoing climate change.
Most of the volume of the troposphere is subzero, where clouds contain ice. There has been controversy about initiation of ice in clouds, especially regarding the identity of aerosol species (‘ice nuclei’) initiating the first ice and the time-dependence of their activity.
The position is part of a larger collaboration between Lund in Sweden, NASA in USA and University of Oslo in Norway since 2019. This international collaborative project has performed lab observations of ice initiation from solid aerosol material, informing the design of microphysical schemes of models of clouds and climate at Lund. A new climate model is being developed to represent cloud processes with more realism in the project.
The post will involve global modeling with this new climate model at Lund to investigate mechanisms for the effect from ice nucleating aerosols on clouds and climate. Focus will be given to impacts on cloud properties and extent, which affect the Earth’s radiation budget. Thus, the post will aim to assess how long-term changes of solid aerosol loading may influence climate change.
Work duties
The researcher will conduct advanced numerical modeling to investigate cloud and climate processes. Key responsibilities include:
- Improving microphysics schemes in a global climate model to represent various mechanisms of ice initiation.
- Collecting and analyzing satellite and other observational data to evaluate and verify the model’s accuracy.
- Assessing the impacts of changes in ice-nucleating aerosols, including those from anthropogenic emissions, on clouds and climate.
The work will involve coding with FORTRAN 90 in a linux environment. The work will be performed in a team of atmospheric modellers at the department.
Qualification requirements
Requirements:
- The applicant must have a PhD degree in atmospheric science or simular.
- Applicant must have work life experience of programming in a linux environment, preferably with FORTRAN.
- Oral and written proficiency in English.
- The PhD must have involved numerical modelling.
It is desirable to have documented knowledge from their university education in:
- Mathematics, especially differential equations.
- Numerical methods and/or computer programming.
- Cloud physics
It will be advantageous if the applicant is experienced with modeling of either clouds or climate.
In the application, applicants should provide evidence of how they meet these requirements.
Consideration will also be given to good collaborative skills and drive, and 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.
Terms of employment
This will be a full-time fixed-term employment (SÄVA 5§ p1 LAS) of 100% for 12 month with starting date 2026-02-01 or due agreement.
