Fig. 4: Temporal evolution of the estimated anthropogenic CO2 fluxes (Fa) and gross primary productivity (GPP) in the street and vegetation sectors using different methods.
From: Carbon uptake of an urban green space inferred from carbonyl sulfide fluxes
Panel (a) shows Fa at the street sector and panel (b) shows GPP from both the vegetation and the street sectors. Night-time data (PAR < 10 μmol m−2 s−1) are omitted. Bins show the median value from 10-day periods, and the whiskers indicate the interquartile range. Orange data with error bars on panel (a) show the median and interquartile range of the bottom-up estimate of fossil fuel emissions on the street sector. It is generalized into the vegetation sector by normalizing values according to the paved land surface area. The number of accepted data points for each group of bins is shown on top of the panels, and only those times with more than 10 points were plotted.
