Biography

Levin was born in Erlangen, Germany in 1953 and studied physics at Heidelberg University. She completed her diploma thesis in 1978, on regional modeling of the atmospheric CO₂ based on C-13 and C-14 measurements, followed by her PhD thesis in 1984 on atmospheric CO₂ sources and sinks across the European Continent. Levin showed an early interest in finding ways to measure greenhouse gases, especially carbon dioxide, on the regional scale and had several significant accomplishments, according to European Geosciences Union:

The measurements obtained through Levin’s efforts are widely used across the geoscience community to characterise associated carbon fluxes and have proven to be extremely important for our understanding of the global carbon cycle. They have provided key insights in atmospheric and ocean sciences as well as in biogeochemistry and climate science.

"for fundamental contributions to our present knowledge and understanding of greenhouse gases in the atmosphere, including the global carbon cycle." She has been the group leader of the Carbon Cycle group in the Institute for Environmental Physics for more than 20 years, and a lecturer at the Faculty of Physics and Astronomy of Heidelberg University. Since the 1990s, Levin's group has also measured the concentrations of methane and nitrogen oxides, with the aim of also using them to measure human impact. Levin died on 10 February 2024.
