a\rangle\approx 0.001\,\ldots\,0.1\mu$m (Fig. \[fig:DusttoGas\]) [ occurring in the terminator and dayside regions]{} remain in the atmospheric regions accessible to transmission spectroscopy of p$_{\rm gas}\approx 10^{-5}\ldots\,10^{-4}$ bar for about 2h, using $H\approx 8\cdot10^6$cm (Fig. \[fig:meanmolweight\]) and $v_{\rm dr}=10^3$cm/s (Fig \[fig:vdr\]). With a slightly smaller nightside scale height of $H\approx 3\cdot 10^6$cm and $v_{\rm dr}=5$cm/s, the respective cloud particles that formed in the low-pressure regions of p$_{\rm gas}\approx 10^{-5}\ldots\,10^{-4}$ bar and grew to a mean particle size of only $\langle a\rangle\approx 10^{-3}\mu$m remain $\approx 170$h (or $\approx 7$ d with a day of 24h). Once the nightside particles have sank into the deeper atmosphere, the time scale decrease considerably as their size increases by orders of magnitudes and, although time scale vary throughout the atmosphere, the settling time scale become comparable to the dayside example stated above.

General material composition of cloud particles
-----------------------------------------------

Figure \[fig:5line\_MT\] demonstrates that the material composition of the cloud particles on WASP-43b does not change dramatically between the day- and the nightside in the low pressure regions where p$_{\rm gas}\approx 10^{-6}\ldots\,10^{-4}$ bar for the 1D profiles inspected in this study: The dominating materials are silicates (\[s\], \[s\], \[s\], \[s\]) and metal oxides (MgO\[s\], SiO\[s\], \[s\], FeO\[s\], \[s\],
