Topics
Investigation of the global hydrogen cycle with isotope measurements
– Source apportionment of carbon aerosol by 14C measurements and modeling
– Inverse modeling of methane using isotopes
– Mass Independent Fractionation (INTRAMIF project):
* CO2+O3 isotope exchange via O(1D) and stratospheric CO2
* Mass Independent Fractionation in Atmospheric Carbon Monoxide and the reaction CO+OH
* Isotope effects in ozone formation and destruction reactions
– Historical budgets of methane and nitrous oxide using air trapped in ice cores
