This paper presents a comprehensive compilation of tropospheric ${}^{14}\text{CO}_2$ (or ${}^{14}\text{C}$) data for the period 1950–2010, covering the pre-bomb, bomb-peak, and post-bomb eras. The compilation, a new version of the 1955–2001 data by Hua and Barbetti (2004), includes yearly summer data sets for zonal, hemispheric, and global levels of atmospheric ${}^{14}\text{C}$. Additionally, monthly data sets for five atmospheric zones (three in the Northern Hemisphere and two in the Southern Hemisphere) are reported. The annual data sets are intended for regional and global carbon model calculations, while the extended monthly data sets serve as calibration curves for ${}^{14}\text{C}$ dating of recent, short-lived terrestrial organic materials. The compilation covers a period before the onset of bomb ${}^{14}\text{C}$ in the mid-1950s, the bomb-peak period in the 1960s, and the post-bomb era up to very recent times. The data sets are based on published radiocarbon data from atmospheric CO$_2$ sampling and tree-ring series, with a focus on minimizing the influence of local fossil fuel combustion. The new compilation extends the data by 5 years before the pre-bomb period and 10 years into the post-bomb era, providing a more comprehensive record for carbon cycle studies and age calibration.This paper presents a comprehensive compilation of tropospheric ${}^{14}\text{CO}_2$ (or ${}^{14}\text{C}$) data for the period 1950–2010, covering the pre-bomb, bomb-peak, and post-bomb eras.
