From: Experimental reaction rates constrain estimates of ozone response to calcium carbonate geoengineering

Fig. 2

a, b Typical uptake signal from the flow tube experiments for HCl + calcite and ClONO2 + CaCl2 reactions respectively. The baseline was subtracted and signal normalized to the background level. c, d Results from long-term uptake experiments and parametric fit results for HCl + Calcite and ClONO2 + CaCl2 respectively. Thickness-dependent uptake coefficients listed in Table 1 are extracted from these fits. Error bars in the data points in c represent systematic error from the experiment. Results from the mass spectrometer measurements are overlaid on the plots. The shadowed regions show 95% confidence intervals of the parametric fit extracted using bootstrapping as outline in the experimental section. The standard errors for fitting parameters A and n (defined in the text) are 0.18 and 0.05, and the covariance is −0.08.
