Current AAPP Activities:
Dr Alexander is working closely with other members of Project 1 to analyse the recent Southern Ocean field campaign datasets of clouds, aerosols, precipitation and radiation. These results will inform future model simulations with the goal of reducing the surface radiation bias presently found in many climate models. His focus is on quantifying occurrence of super-cooled liquid water clouds and precipitation phase within high-latitude cyclone systems; and is currently constructing a seasonal climatology of clouds from Macquarie Island.

More about Simon
Biography
Dr Simon Alexander is a Senior Research Scientist at the Australian Antarctic Division. His research interests include Southern Ocean and Antarctic clouds, precipitation and aerosols. Clouds remain one of the key sources of uncertainty for estimating global climate sensitivity. Many climate models have a large surface radiative bias over the Southern Ocean, which is traced back to uncertainties in our understanding of clouds. The clouds and aerosols present over the Southern Ocean are different from those in other regions of the world, due to the pristine nature of the air and minimal anthropogenic aerosol influences. He also has research interests in polar ozone and polar stratospheric clouds, and has contributed as co-author or contributing author to the quadrennial WMO ozone assessment reports since 2014.
Dr Alexander was a leading investigator on recent major international Southern Ocean field campaigns designed to measure properties of clouds and aerosols from air, sea and land. He is currently working with collaborators to analyse these data and use them to improve atmospheric model simulations. More recently, he has contributed to the Year of Polar Predictability (YOPP) Southern Hemisphere winter campaign, with co-ordination of a range of ground-based measurements made from Davis.

Dr Herraiz-Borreguero received her PhD in physical oceanography in 2010 from the University of Tasmania. Before joining CSIRO in June 2018, Dr Herraiz-Borreguero was a Marie Curie Research Fellow at the University of Southampton, UK. During this time, her research evolved from open ocean/large scale physical processes in the ocean to polar oceanography and Ice shelf-ocean interactions.

She led several papers on the coupling of the ocean with the Amery Ice Shelf, East Antarctica. This work used a unique set of observations from boreholes drilled through the ice shelf by the Australian Antarctic Division’s AMISOR project.
Laura provides feedback on field campaigns and contributes to AAPP Themes 1 and 2. She works on Southern Ocean change using observations, and on the interaction of the ocean with ice shelves around Antarctica.

CSIRO Profile（https://people.csiro.au/H/R/Ruhi-Humphries）
About Ruhi & AAPP Involvement:
Ruhi's work within AAPP revolves around increasing our understanding of atmospheric aerosols in the Southern Ocean and Antarctica. This is done using ongoing measurements from the RV Investigator and Cape Grim as well as a range of intensive field campaigns at Antarctic research stations and aboard various ship-based platforms. The goal is to close the gap in our understanding of the sources, sinks, chemistry and physics of aerosols in the region, which has been driven primarily by the dearth of measurements in the past. Because aerosols are key to the radiative balance, as well as cloud formation and properties, Ruhi collaborates closely with cloud researchers at AAD and the BoM.
