None at present | ai985 vs ah813 | Run for 20 years - plots based on last 10 years; Biogenic ems prescribed; No trop het chem; Lightning ems 10.7 TgN/yr; CH4 lifetime too short; Strat o3 max reduced and in better agreement with obs; Diagnosed STE flux of O3 clearly wrong. Updated pdf now includes updated methane lifetime calculation and nh_oh/sh_oh ratio. |
