Figure 9: Ozone over Africa and in situ potochemical ozone production in the TWP.
From: A pervasive role for biomass burning in tropical high ozone/low water structures
(a) Vertical distribution of CAM-Chem O3 in the African biomass burning region (that is, black box Fig. 4); 5th, 25th, median, 75th and 95th percentiles are shown. (b) Mean ±1σ of SHADOZ ozonesonde observations over Nairobi, Kenya for January and February 2014 (red). Mean ±1σ CAM-Chem O3 modelled over Nairobi sampled on the same days as the ozonesondes (blue). (c) O3 profile from Fig. 2b (red) and net O3 production in the profile (purple, top axis), calculated using the DSMACC photochemical box model (see Methods section).
