The carbon cycle group at IUP investigates the biogeochemical cycles of long-lived greenhouse gases such as CO2, CH4 N2O and SF6 on the regional but also on the global scale. 

We measure their long-term atmospheric trends and for CO₂ also the radiocarbon (¹⁴C) content. Further, atmospheric ²²²Radon activity concentration measurements are conducted as we use this natural radioactive noble gas as tracer to evaluate atmospheric transport processes. In collaboration with the  Max Planck Institute for Biogeochemistry in Jena these data are evaluated based on regional and global atmospheric transport models.

In the last decade, the IUP carbon cycle group contributed to the design and implementation of the European Research Infrastructure ICOS (Integrated Carbon Observation System) and has set up in Heidelberg the Central Radiocarbon Laboratory (CRL) as part of the Central Analytical Laboratory of ICOS.
