Modification of Tracegas Scenarios
Brapho Box/Slimcat CTM derived stratospheric climatology (Marco Bruns) SZA and albedo dependence of photochemistry tropospheric modification introduced
constant tropospheric O3 number density profile (all)biomass burning/ biogenic emission (5N, July)
H2CO 2ppb < 3 km (may affect BrO fit) NO2 taken from MPI-2D CTM O3 doubled < 5 km
free tropospheric BrO (55N, April) BrO 1ppt < 10 km (Fitzenberger et al., 2001)
PBL BrO explosion (75S, October) BrO 50ppt < 2 km O3 0ppm < 2 km
