Dr. Samuel Hammer
Samuel Hammer studied physics at the Heidelberg University and completed his diploma and doctoral thesis at the Institute for Environmental Physics. In his diploma thesis he dealt with the spatial and temporal variability of terrigenous and cosmogenic radionuclides, including 14C in atmospheric aerosol. In the course of his PhD he gained extensive experience in high-precision measurement of atmospheric greenhouse gases by gas chromatography and investigated the regional balance of atmospheric H2 in Heidelberg. He then applied the experimental experience gained to the improvement of in-situ FTIR spectrometers during his postdoctoral work. Another focus of his work was the development and testing of a comprehensive quality management system for in-situ greenhouse gas monitoring stations.
Samuel Hammer’s main scientific interest is the analysis and interpretation of high-resolution greenhouse gas data for the determination of regional greenhouse gas fluxes, using special multitracer approaches and 14C for splitting the fluxes into fossil and biogenic source fractions.
Together with Prof. Butz and Dr. Schmidt, Dr. Hammer will focus on the theme 1b – the Top-down atmospheric observation. More specific he will do In-situ measurements (with focus on radiocarbon for future CO2 system) in order to identify super-resolving target regions.
