Barbara Dix

Barbara Dix is a Research Scientist with the Cooperative Institute for Research in Environmental Sciences (CIRES). She received a PhD in Environmental Physics from the University of Heidelberg in Germany in 2007. In 2019, she joined the de Gouw group to work on the analysis of satellite remote sensing data over oil and natural gas production regions. Since 2022, she is also working on the analysis of TROPOMI observations in wildfire plumes.
