Latitudinal variation. (a) K_zz, (b) H₂SO₄ vapor upward diffusion flux, and (c) H₂SO₄ vapor eddy diffusion velocity profiles in different latitude bins were derived by adopting particle distributions from the microphysical model results (McGouldrick & Barth 2023). The red, green, and blue lines represent the latitudinal bins of 0°–30°, 30°–60°, and 60°–90°, respectively. Panel d presents the altitude-latitude distribution of derived K_zz. We note that the missing middle-latitude results near 47 km are caused by a lack of data.
