PhD Student in Physics with Focus on Satellite Observations of Stratospheric Aerosol

Popis:

Lund University was founded in 1666 and is consistently ranked as one of the world's leading universities. We have approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our mission to understand, explain, and improve our world and the conditions of people. Description of the Unit This position is located at the Division of Combustion Physics, Department of Physics, Lund University, within the stratospheric aerosol research group led by Associate Professor Johan Friberg. The division hosts research groups working across a broad spectrum of applied physics and optical diagnostics, including laser-based measurement techniques, combustion science, and atmospheric science. This environment offers a stimulating and technically diverse workplace where expertise in optics and light–matter interaction is central — a natural home for satellite lidar research, which is fundamentally an application of laser remote sensing. The doctoral student will become part of an active research environment with postdoctoral researchers and senior scientists with expertise in satellite-based remote sensing, atmospheric physics, atmospheric chemistry, and climate modeling. The group is part of the strategic research environment MERGE (Modelling the Regional and Global Earth system) and LTH's thematic area on Aerosols, providing access to a broad network of researchers at Lund University. The project involves collaboration with leading international research groups and institutions, giving the doctoral student the opportunity to engage in the global research community in stratospheric aerosol research early in their studies. Being a Doctoral Student As a doctoral student, you are both enrolled as a student and employed by Lund University. As a research student, you are trained in a scientific approach. In short, you gain practice in critical and analytical thinking, learn to solve problems independently using appropriate methodologies, and develop research ethics awareness. Additionally, as a doctoral student, you have the opportunity to work on projects, develop your leadership skills, and enhance your pedagogical abilities. Throughout your studies, you are guided by supervisors. Research studies culminate in a dissertation and a doctoral degree. More information on being a doctoral student at LTH can be found at lth.se. Field and Project Description Doctoral Project: How Much Cooling Are We Missing? Space Lasers for Better Climate Projections Every major volcanic eruption and large-scale forest fire is a natural experiment in climate impact — they inject millions of tons of particles into the stratosphere that shade the planet and temporarily cool the climate. This doctoral project focuses on the stratosphere and, specifically, on understanding how volcanic eruptions and forest fires affect stratospheric aerosol and what this means for climate. Accurately quantifying these effects is crucial for reliable climate projections — and there remains significant potential to better utilize the unique perspective that satellite lidar offers within the multi-instrument climatologies for stratospheric aerosol used in international climate model intercomparisons. A satellite lidar such as CALIOP — fundamentally a laser fired from orbit — offers a fundamentally different and complementary view of stratospheric aerosols compared to other satellite techniques. This project will utilize a unique 17-year dataset from CALIOP to critically evaluate and improve how lidar observations of stratospheric aerosol are currently included in multi-instrument climatologies, and to produce refined lidar-based estimates of stratospheric aerosol burden and its climate impact for use in the next generation of international climate model intercomparisons (CMIP). The goal is to create a richer and more complete picture of how volcanic eruptions and forest fires burden the stratosphere with aerosols and the resulting cooling of Earth's climate. Beyond this primary objective, the project opens toward broader scientific exploration of the stratosphere. The group's research spans multiple aspects of stratospheric composition and its climate relevance, including trace gas measurements that complement aerosol measurements, as well as development of new data products from ATLID — the lidar instrument on ESA's recently launched EarthCARE satellite, which applies a new generation of spaceborne laser remote sensing to stratospheric aerosol research. There will be opportunities to contribute to and benefit from these and other parallel research threads within our group. The project sits at the intersection of satellite remote sensing and climate science, and you will work in a team spanning both worlds — satellite data analysts and climate modelers — as part of broader research work at Lund University. If you want your doctoral degree to leave a measurable impact on how the research community quantifies one of the most important natural climate drivers on Earth, this is the project for you. Duties You will primarily devote yourself to your research training, which includes participation in research projects, research training courses, seminars, and conferences. Your responsibilities will include: You will have specific responsibility for analyzing high-resolution satellite lidar data to quantify how well current climate simulations capture the cooling effect of volcanic eruptions and large forest fires. You will present your results at international scientific conferences and participate in the graduate school ClimBEco (www.cec.lu.se/climbeco-graduate-research-school). The position includes travel to international conferences. Your duties also include participation in teaching and other departmental work up to a maximum of 20% of your time. Your responsibilities also include contributing to teaching and other departmental work (however, no more than 20% of your time).
