Dr Brown will lead the Climate Science Centre (CSC), which was established in August 2016 and united CSIRO's atmospheric, ocean and climate observation and modelling capabilities. The CSC collaborates with local and state governments for climate adaptation and mitigation across many sectors, including agriculture and energy.
Director CSIRO Oceans and Atmosphere Dr Tony Worby said he was looking forward to the next phase of the CSC under Dr Brown.
"I am delighted that Jaclyn has agreed to lead the Climate Science Centre. She brings incredible enthusiasm and vision to the role," Dr Worby said.
"Jaclyn is a natural networker and connector, and I'm confident that her experience engaging with external stakeholders across the community - and with industry - will serve the Climate Science Centre well in the coming years."
Dr Brown said that she was excited to commence in the role in January 2020, where she will be based in Hobart.
"Drought and climate change are two big issues Australia is facing. The Climate Science Centre has an important role to play in providing the best information and forecasts to the people that need to make decisions for our future."
"Determining how we can deepen our collaboration with government and industry to address these challenges is something that I'm excited to tackle."
Dr Brown completed her PhD at UNSW and undertook a Postdoc at Yale University in the USA, and an OCE Postdoc at CSIRO.
"We will continue to focus on our world-class climate system science capability, delivering quality science for national benefit, and working with our international collaborators," Dr Brown said.
Outgoing CSC Director Dr Helen Cleugh, who is taking a step down from the leadership role, will continue to work alongside Jaclyn at the CSC.
