Longitude-height section (0–140°E) of CO (ppbv), averaged over the southern portion of the AMA (22–30°N) and associated vertical motion (Pa s−1) field with solid (dashed) contours indicating ascent (descent) superimposed, for (a) PRM and (b) PKM. Panels (c) and (d) are the same as in (a) and (b) respectively, except for CA (ppbm). Panels (e) and (f) are the same as in (a) and (b) except for dust aerosols (ppbm).
