Periodic Reporting for period 1 - Clumped Isotopes (Reconstructing atmospheric oxidation processes in the past with clumped isotope measurements in O2 trapped in polar firn and ice air)

In this project we proposed to understand the present and past atmospheric photochemistry using clumped isotopes in O2 in the atmosphere and that trapped in firn and ice core air. Clumped isotopes are the abundances of the isotopologues in which two or more rare isotopes...
