Dear colleague!

 

We would like to draw your attention to three new PhD openings in atmospheric physics at the University of Vienna:

-          (2) Open position(s) with Prof. Bernadett Weinzierl

1. Airborne measurements of the complex refractive index of atmospheric aerosol layers

In April 2017, the A-LIFE aircraft field experiment (www.a-life.at) was conducted in the Eastern Mediterranean to investigate the properties of absorbing aerosol layers (mineral dust-black carbon mixtures) during their atmospheric lifetime. The overall aim of this PhD project is to determine the complex refractive index of single aerosol particles in complex aerosol mixtures. This includes the characterization and further development of a novel instrument for vertically‐resolved measurements of complex refractive index and size of single aerosol particles, the analysis of data from the A-LIFE field experiment, and the collection and analysis of new data.

 

2. Assessing the partitioning between mineral dust and black carbon absorption in aerosol mixtures over the Eastern Mediterranean

Recently it has been shown that the climate impact of black carbon (BC) is twice as large as originally thought. Due to the rather short lifetimes of BC in the atmosphere (on the order of days to weeks, compared to decades and longer for the main greenhouse gases) as well as its strong warming potential, BC reduction and mitigation strategies are expected to provide climate benefits. However, the attribution of absorption to different aerosol types is challenging. In particular in aerosol mixtures it is still an open research question whether mineral dust absorption is frequently misclassified as BC absorption. The overall aim of this ERC-funded PhD project is to study the partitioning between mineral dust and BC absorption in aerosol mixtures which we investigated during the A-LIFE field experiment (www.a-life.at) in the Eastern Mediterranean in April 2017. This project includes the analysis of in-situ size distribution data of total aerosol and BC, the derivation of optical properties, and the assessment of mineral dust and BC contribution to the total absorption for the investigated aerosol layers.

-          Open position with Prof. Paul Winkler
Nucleation and growth rate measurements from anthropogenic precursors in chamber and field experiments
An open PhD position is currently available in the framework of a Marie Sklodowska-Curie Innovative Training Network called CLOUD-MOTION. The successful candidate will conduct experimental studies of nanoparticle formation using cutting-edge instrumentation for nanoparticle detection and sizing. This work will partly be performed at the CLOUD experiment at CERN, Switzerland. In addition, field experiments in Vienna are planned to investigate urban nucleation.

 

The application process runs through the Vienna Doctoral School in Physics (VDS-P) and registration is possible until July 30.
Attached you will find the poster for the open call and further information on the admission process can be found here.

We would be very grateful if you could forward this information and the attachment to qualified students who might be interested in performing their doctoral work at the University of Vienna.

 

Feel free to approach us in case you have any questions or comments.

 

With many thanks in advance.

 

Warm regards on behalf of the VDS-P Team,
