Fig. 4: 2019 annual mean changes in surface concentrations conditional on BB.
From: Changes in atmospheric oxidants teleconnect biomass burning and ammonium nitrate formation
The impact of BB emissions on a HOx, b NOx, c HNO3, and d NH3. All concentration changes were computed by subtracting the NBB model run from the BASE model run. The four black rectangles are positioned over the same high population areas in eastern USA, northwestern Europe, the Indo-Gangetic Plain and eastern China shown in Fig. 2.
