Dimethyl sulfide (DMS) is a biogenic source of sulfate aerosol that influences the climate system by reducing solar radiation and altering cloud properties. Recent observations suggest that DMS may play a dominant role in the aerosol and cloud formation along the Antarctic coast where DMS is produced by marine microbes that reside on top, in, and under sea ice. However, the role of DMS remains unclear especially over the regional scale, partly due to the lack of compilation of DMS data.

Compound events (CEs) caused by a combination of multiple drivers often result in more severe socio-economic and ecological impacts than conventional events. One example for CEs with the potential to cause considerable negative impacts on crop yields and human health is the cooccurrence of hot and dry conditions. The student will work with climate model output from Earth System Models participating in the sixth round of the CMIP6 and assess what impact a gradual increase followed by a decrease in atmospheric carbon dioxide has on the occurrence frequency of hot and dry CEs.

Due to the lack of appropriate historical datasets, quantification of shifts in global extreme precipitation intensity has not been possible so far. This project will use a recently developed long-term global dataset of daily precipitation alongside a dataset of global temperature changes to calculate the CC scaling for broad climatic regions across the globe.

Recent research has shown that mean (raining) and extreme (pouring) changes can align in some regions. This project will use a recently developed long-term global dataset of daily precipitation to answer why, how and where changes in mean frequency and intensity align with changes in extreme frequency and intensity of precipitation.

This project aims to quantify the disproportionate exposure to urban heat intensity across major Australian cities. Urban heat stress poses a major risk to the health and wellbeing of urban dwellers. Case studies of individual cities suggest that environmental stressors such as urban heat may be unequally distributed across income groups.

The student will work with climate model output from Earth System Models participating in the sixth round of the Coupled Model Intercomparison Project (CMIP6) to assess how a gradual decrease in atmospheric carbon dioxide impacts carbon uptake and storage in the global ocean. Together with a partner project this project will test the reversibility of carbon emissions in terms of the marine system.
