"Estimating fossil fuel carbon dioxide (ffCO2) emissions\r\nin the Rhine Valley metropolitan region\r\nfrom local atmospheric observations in Heidelberg"^^ . "This cumulative dissertation investigates the potential of radiocarbon (14C)-based and carbon\r\nmonoxide (∆CO)-based fossil fuel CO2 (∆ffCO2) estimates from the urban observation site\r\nHeidelberg to deduce the seasonal cycle of the ffCO2 emissions in the Rhine Valley. For\r\nthis, the CarboScope inversion system is used to investigate the benefit of few but accurate\r\n14C-based ∆ffCO2 estimates from about 100 hourly flask samples collected in 2019 and 2020,\r\ncompared to a continuous ∆CO-based ∆ffCO2 record with about 4 times larger uncertainty.\r\nThe urban observation site with large ffCO2 point sources in the vicinity places special\r\ndemands on the transport model. Therefore, a method is developed for the high-resolution\r\nWeather Research and Forecasting - Stochastic Time-Inverted Lagrangian Transport model\r\n(WRF-STILT) to represent the effective emission heights of point sources. This work shows\r\nthat the 14C-based ∆ffCO2 observations contain the seasonal cycle of the ffCO2 emissions,\r\nbut do not lead to robust inversion results. In contrast, the continuous ∆CO-based ∆ffCO2\r\nestimates provide robust and data-driven seasonal cycles that show the distinct COVID-19\r\nsignal in 2020 and are suitable for validating the amplitude and phasing of the seasonal cycle\r\nof the emission inventories in the main footprint of Heidelberg."^^ .
