Fig. 16. Effect of two strategies on O 3 concentration (ppb) fields for the 7th Feb 2006 at
1300LT ground level. Figure 16(a) represents the reduction of O 3 concentration in 2015 from
the ozone concentration in 2006. Figure 16(b) represents the reduction of O 3 concentration in
2020 from the ozone concentration in 2006. The measurement stations are shown in Fig. 13.
Analysis of O 3 at different measuring stations
Strategy in 2015: Figure 17(a, b, c)-upper panels shows the reduction of O 3 concentrations
( O3
in equation 4) in 2015 from the O 3 concentration in 2006 and its uncertainties (
in
O 3
equation 5) in different stations (we consider the standard deviation as the uncertainty).
The Delta O 3 ( O3
) and uncertainties of O 3 (
) presented on Fig .17 are calculated using
O 3
equations (4) and (5). These values are calculated from 100 MC simulations for the base case
and 100 MC simulations for each strategy.
