Dai, Zhen; et al. (2020): Experimental reaction rates constrain estimates of ozone response to calcium carbonate geoengineering

Dai, Zhen; Weisenstein, Debra K.; Keutsch, Frank N.; Keith, David W. (2020): Experimental reaction rates constrain estimates of ozone response to calcium carbonate geoengineering. In Commun Earth Environ 1 (1), pp. 1–9. DOI: 10.1038/s43247-020-00058-7.

"We reduce uncertainties in ozone response to CaCO3 via experimental determination of uptake coefficients and model evaluation. Specifically, we measure uptake coefficients of HCl and HNO3 on CaCO3 as well as HNO3 and ClONO2 on CaCl2 at stratospheric temperatures using a flow tube setup and a flask experiment that determines cumulative long-term uptake of HCl on CaCO3."
