Notes. The abundances of all line-absorbing species are converted to log volume mixing ratios. For the more complex cloud model, log (Pcloud) is the cloud base pressure log (Pbase) (see Eq. (2)). For a description of the cloud models, see Table 3.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
