Project Summary of the Season 2017/18
Project Summary of the Season 2018/19
We have commenced data analysis using the precipitation data collected aboard ships in the Southern Ocean during the preceding summer 2017/18. Initially, we are focussed on quantified oceanic precipitation to understand why satellite retrievals fail at southern high latitudes.
Project Summary of the Season 2019/20
Final Summary of Project Achievements
While data analyses and journal article preparations are ongoing, some of the highlights to data from PLATO include:
1) Latitudinal quantification of microphysical properties of oceanic precipitation, and in particular the unique Southern Ocean environment
2) Detailed observational and modelling of an atmospheric river event at Davis, including the low surface precipitation
3) Increased understanding of cloud-aerosol-precipitation interactions in the waters near Antarctica, and over coastal Antarctica itself
The PLATO datasets are still being used across multiple institutions, including the AAPP for research, thus we expect continued outputs over the next few years.
